starter--and headlights

[adh383]

OK guys, Its all bolted together--now i need a bucket of info. someone told me a while back about which wires to run to the starter. Lost my notes on that, so someone refresh my memory on that. i also do not have headlights or taillights. i got signals and brake lights. since the power comes in at the starter-i fiogure once it goes to the switch, then i\'ll have all the lights workin. Can ya help me? Thanks, Dennis

O.K. fat purple wire to the male prong on your mini starter.(think you said you had a prong?) batt to center stud on starter. and wire from center stud on starter to bulk head connection on firewall by trans dipstick. thats it. then of course wire from batt to alt for charging.

[adh383]

I have the purple wire to the male clip on the starter battery cable to the main post on starter---have 3 red wires coming from the bulkhead-----one of them is hooked to alt. I have a one wire alt. the other 2 red that come from the bulkhead run together into a round black fuse. i guess it is a fusible link. out of that fuse comes a black wire that i have hooked to the main battery post. also- what about 2 wires that plugged into the 2.8 alt.in the same plug?

[ZR1BLAZER]

ok with the 1 wire alt you dont want the wire with the plug to alt wired to the bulk head. that would mean that your (forgot the name of it?? brain fart) but your alt will be powered up constantly. you dont want that. that wire needs to go to the....... hold on i will take some pics real quick label them and you can see what i am saying.

ok look i am going to post the pics in a sec. but, 1st you need to get the alt straight. the bolt on the back side of the alt is the charging curcit. you run your wire from there to the batt. for charging. and the other 2 into 1 wires with the fusable link my need to go back to bulk head. you need to check all that with test light.

[ZR1BLAZER]

hope this does you some good.

[adh383]

So I am gonna have 2 wires on the main starter post plus the pos. battery cable

[ZR1BLAZER]

i thik you are talking about the 2 pics? i just showed you both ends of the wire that goes from the bulk head to the starter.

[adh383]

tHANKS-ZR1--i\'LL GIVE IT A SHOT TOMORROW. EALLY APPRECIATE THE TROUBLE YOU WENT TO ON THE PICS.

[ZR1BLAZER]

no problem. thats what we are all here for. good luck.

[adh383]

THANKS. DENNIS

[adh383]

No luck yet zr1==since my battery is in the bed--where should i run wire off alternator? Or which existing wire would work?

[ZR1BLAZER]

are you using the bulk head still? and when you say no luck do you mean with the headlights?

[adh383]

I took the wire i had off the alt. It was hot all the time. I think my brain is not WIRED for electrical . ????? no head lights yet -nothing? The two wires that are factory coming from the bulkhead are red. They are tied into a fusible link--then only 1 black wire comes out of the other side of that link. --i have that hooked to the battery post on the starter. got the purple wire on the male clip on the starter.

[ZR1BLAZER]

ok so for the plug that plugs to the alt. you need to run that to the inside and tap into the fuse box on a curcit that is hot only when keyed on. but why was that wire cut? or did your alt have a 2-3 wire hook up originally? as far as the headlights. man that could be anything. if you have a test light.

with all your wires wired to the bulk head you need to check the fuse box with the keys on. if all curcits are hot the it might just be a bad headlight switch? if you have alot of problems PM me with you # and i can call you and we can walk through this. since my whole front clip is off gettin to all the wires right now will be a breeze.

[ZR1BLAZER]

the 2 to 1 wire should be running into the truck to the fuse box?? man if you can snap some pics and email them to me that would help. then i can label them and send them back to you.

[ZR1BLAZER]

one more thing. if you dont have any wires coming from the bulk head to the inside of the truck any where. how are you getting power to the rest of the truck??? nothing should be powered up the whole system should be dead?? we need to talk for sure.

[adh383]

this is an 84 model--2.8 original engine. had the plug and another wire for the old alt. i have a one wire alt now. which wire do i use? My battery is in the bed. where and what wire do i use to get my alt. to work? this shit is really pissing me off.know what i mean/ all the factory wiring is still in place.

[adh383]

there arev only 2 wires coming from the bulkhead---both go into a single roung black link and then 1 black wire comes out of that link. i have that hooked to the starter. i have signals--door buzzer--hazard lights--alt and oil light comes on when i turn the switch on. no horn headlites--parklites. also have wipers.

[adh383]

could\'nt retrieve your pm -----zr1 thanks for your effort--

[ZR1BLAZER]

sorry i couldnt help more. its just to hard to go into wiring detail on the computer.

[adh383]

Yep you got that right---not only do i hate electrical stuff-- this computer is almost as bad of a hassle..lol thanks man---guess i am gonna get a local spark to come bring me a goody\'s for my headache lol I\'ll let ya know if any progress is made.. thanks again.

[adh383]

Hey ZR1---what an oversight i just discovered-my truck was a 5 speed--now it\'s an automatic--you got to push the clutch in for it to crank--lol not concerned about the headlights just yet---can I just disconnect that clutch switch or what--and since the old alt. had a 2 wire plug and a wire screwed to the back of alt. wonder if i can just use the red wire that is in the 2 wire plug?

[ZR1BLAZER]

its either the white or red for sure? but check it with a test light or volt meter. only one will power up when the key is turned on. and thats the one you use.(i think the red?) you should be able to just disconnect the clutch switch. but pay attention to what you do because if it doesnt work you will have to rewire it as is theclutch was pushed in all the time.

[adh383]

I checked the red and the black wires on that alt. plug-only the black comes alive when i turn on the switch--gonna hook it to alt. Doesnt make sense --the big red wire that was hooked to the old alt. is hot all the time. guess that\'s another puzzling thing about the JUICE. I\'ll deal with the lights later--ready to hear that huzzy run.

[ZR1BLAZER]

the big red wire that bolts to the alt right? thats the one that is powered up always? that is the wire that charges your battery when the motor is running. you need to bolt that to the stud on the back of the new alt and follow the wire to make sure it makes its way back to the battery. even if it goes to the bulk head. it stil make a complete curcit.

[adh383]

in an earlier response--you said if it was powered up all the time-to take it off alt. If i put it back on the alt--i\'ll have 2 wires on a one wire alt. you said if it went to the bulkhead to take it off?????????

[ZR1BLAZER]

no no no. 1 wire alt means that the plug ONLY has 1 wire. some had 2 or 3 wires that did other functions. the 1 wire alt does all those things internal. the 2nd wire which bolts to the back of the alt(all alt in all cars) is for the charging curcit. THAT wire must bolt to the back and go to the batt. it will be hot always. but the wire that goes to the PLUG must only be hot when keyed.

[adh383]

Damn now i am really confused--one more time---the old alt had one big red wire to the post --it had 2 wires in one plug that plugged into the alt. one is red one is black. which wires do i put where?

[ZR1BLAZER]

big red wire to post= back to post on new alt.

which ever wire (red or black) that is hot only when the key is on is the 1 wire that goes to the new plug to the alt. http://www.s10v8.com/images/smilies/icon_biggrin.gif

[adh383]

just talked to my local speed shop---they said to run i wire from the main post on the starter to the post on the alt. ??????? hell if i know!!!

[ZR1BLAZER]

yes. you can run the wire from the post on the back of the alt to the starter, battery, or the bulk head. as long as it all goes back to the battery. it has to make a complete curcit.

[adh383]

gonna try it-see what happens--just seems to me--why run another wire when i got those 3 that went to the old alt. ?

[ZR1BLAZER]

i think you are misunderstanding what i am saying? if you want call me 1-985-868-6468 ask for dayna. i cant explain this on the computer.

[ZR1BLAZER]

HAHAHAHA so whats up? did you get the lights to work now? i hope that call cleared it all up for you. let me know what happened.

[adh383]

I got lights when i hooked the 2 alt. wires to the alt. still got the 2 red that run into a black after that fuse link --it is hot. got to do something with it?

[ZR1BLAZER]

if it is hot run it to the bulk head like we talked about. it wont hurt because the bulk head stays hot always any way. and it is better then tapeing them off and tucking them some where. i am glad i was able to clear up the alt and 2 wire 1 wire difference for you. take it easy and lut us know when you get it fired off.

[adh383]

i forgot to mention--my battery light in the dash is on all the time--thinkin it\'ll go off when i crank it up.

[ZR1BLAZER]

is it on when the key is on or all the time? even with key off? if it is on when the key is off then swap the 2 wires plugged into the alt. and see what happens

[adh383]

no matter which male i hook the black wire to --my battery lite and the buzzer which tells you your key is in or your door is open is on. when i unhook the black wire--lite goes out and buzzer stops

[ZR1BLAZER]

but is this happening with the key off and out of the ignition? you said the black wire was only hot with key on. how about the red one? is it hot all the time or dead? if hot always try just the black one and see if everything works like it should.

[adh383]

does not matter--key in or out-----anytime black is on alt. lite and buzzer is on---the red is the one that is hooked to the bulkhead--

[ZR1BLAZER]

you said there were 2 wires that used to have an original plug on it. red and black. that red wire not the big fat one we cleared that up. the red and black on the original plug outa run together.

[adh383]

???????? beats me!!!

[ZR1BLAZER]

HAHAHA this is hard as hell. ok IF the skinny red wire that is with the black wire is hooked to the bulk head then unplug it from the alt and leave just the black and see what it does.

[adh383]

ANYTIME black is hooked to alt. light and buzzer are on. think about it lol--- goin to the drag strip--later, dude.

[ZR1BLAZER]

have to go offshore tonight. i hope you get it. when i get back i will PM you to see if you got it. later

[406v8]

Hi guys,



I have a opposite problem but it seems that you guys are talking about the 2 same but different circuits.



My problem is that the headlights &amp; tailights and horn circuits work fine. But and this is the really scarry problem.



The other circuit through the keyed ignition circuit will cut off and yes sometimes on the highway while in traffic ala no engine.



I have pulled out the unused computer, a new battery, checked the ingnition switch seems ok, new ground wires to engine, frame and body, rechecked disonnected wires that they are properly blocked off.

(V8 vs 2.8)



Sometimes it will die and then 15 minutes later its all fine and will start, either hot or cold it will do this.



In looking at the wiring you are talking about you are refering to the hot side over the starter.



Could it be related to starter, alternator going weird,

HEI igniter?. what is in front of my face that I am missing. disconnected 2.8 fuel pump.



Last time it died I had just stepped on the brake.



Also whn this happens the disconnected stock tach jumps up and stays at 1000 rpm. When the thing is unused. Goes back to zero after the problem goes away. till the next time.

[adh383]

Hey 406---as you may have noticed--I ain\'t much on electric issues but if you jiggle the switch-does that make a change? Just guessing!!!!!!! you are bound to have a connection kinda loose-or something is getting hot--then it cools and runs again. Is your starter really close to headers or manifolds? I don\'t have a clue-just a few maybee\'s.

[sk8ordie]

sorry to jump in on this thread, but i\'m in the same wiring nightmare and i have a question too. there\'s a plug that clips into the alt, but obviously the stock alt and v8 alt have a different plug, can i cut the wires and splice the v8 plug in? or do i even need this?

[adh383]

Here again-i\'m not much on elect. I just put the same 2 wires on my 84 2.8--in the same place on my new alt. On mine--the smaller wire was at the top of the plug--the big red is the lower wire in the plug.

[DMONOTJR]

i also HAD wiring problems with my coversion, but i went to the local auto parts store and bought the haynes s10 book and read the wiring schematics in it. they helped me understand the oem wiring and gave me a godd knowledge in where to go with the wiring for my conversion! i also have a book for a early 80\'s truck, to help with the 350 wiring.

[adh383]

Hey Dmon- what knid of problems did you have? what year is your truck?

[ZR1BLAZER]

did you figure it out??

[adh383]

think so we\'ll see soon
