I am having problems starting my truck. I went out to start it the other night, and it barely turned over and then died. Dang, dead battery right? Tried jumping it, same thing. Brought battery back where i bought it, its a 2 month old optima red top, they tested it good. Dang, what else could it be besides the starter? replaced that, its original with 100k on it, still nothing. I turned the motor over by hand with a breaker bar and it seems fine, checked ground from battery to block, fine, checked connections, seemed ok, swapped relays, still nothing. all i am getting is a click from the solenoid and the starter gear popping to the flywheel. Anybody have any suggestions?? It won't even turn the motor.

 

Check for a voltage drop across the battery cables, one at a time. They may look OK but could be corroded internally, and not allowing enough current to flow to the starter.

 

thats the only thing i think it could be, its a relatively simple circuit but im having a tough time with this one.

 

try a different battery if you are able to, I don't trust auto part store battery tests.......the possibility is still there that your battery is NFG

 

Optima's do that, I'll never buy another one.

 

tried a newer one out out of my other truck, same thing. ill mess with the battery cable tonight if i get a chance

 

sounds like it needs a new starter. have someone hold the key and tap the starter with a hammer. if it spins it is bad.

 

its a brand new starter, doing the same thing the old one was, no change.

 

It's still doing it even after turning the motor by hand? That rules out a messed up flywheel I guess.

Hmmm.

 

I dont know joe but the oil in my truck is getting old and its too cold outside to do it out there so get the damn thing out of the garage so I can change it lol J/K
