No power!

[BadBowtie]

hey everyone. im trying to get my truck back into running shape again. right now i got the truck pushed back into the garage so it can warm up. but right now i but the battery charger on it and even after 15-20 minutes i cant get anything. no lights, nothing. i know there is a big problem somewhere but im not really sure where i should start looking. i really dont like dealing with electrical. it seems like the longer the truck sat for the more problems it has. a week ago i had it running but it would stall out for some reason but no i have no elcetrical power at all. can anyone help with this?

#1 guess = connections on the battery:

Remove cables , clean terminals, clean connections, reconnect tightly.

#2 guess = Bad ground on the other end of the battery ground cable:

Disconnect, ensure clean contact, reconnect tightly.

#3 guess = loose connection on starter.

Disconnect battery ground cable, tighten all starter connection, reconnect battery ground.

#4 guess = Dead battery:

Remove, have it tested, replace if necessary.

#5 guess = gremlims!!!!! Goodluck.

you can try and put a volatage tester on the battery and see what kind of voltage you get out of it if its below 10.5 your truck wont start if your not getting any lights or anything at all it could be a bad battery it happen also as ferg said check all your connections use a wire brush to clean them all. even if your battery is dead and you have to replace it clean all the contacts... does your charger have an output showing how many amps is going into the battery?
