Can't catch a break
I was supposed to go get some new rims and tires for the truck, but alas, something is wrong again. The truck barely turns over, it was working fine till I put a new steering column and some suspension pieces in. New battery, cables are less then a year old, and starter is about 6 months old. Got fed up, said some nasty things, you know the drill. So now I will have to do a voltage drop test tomorrow when I bring my power probe home from work. If it's not one thing it's another.

Re: Can't catch a break
I had a similar issue with the neighbors 68 Firebird it would try to crank then would not. put a booster on it. It would start then nothing after changing solenoids and checking wires 3 hours later I wiggled the battery terminal on the brand new cable and the molded end was bad. I wiggled it out about 1/4 inch and it turns over like crazy. Turns out new cable is defective.

Re: Can't catch a break
I have a feeling in might be cable too. There both new, but I did get them from autozone. I will probably go get some welding cable and make new ones just for the piece of mind if nothing else!

Re: Can't catch a break
Check voltage at the starter. Where is the Negative cable grounded?

Re: Can't catch a break
Negative is grounded to frame. Pretty sure is my broken engine to chassis ground strap. I'll put a new one on Saturday and try again

Re: Can't catch a break
Yes that may be it. Usually I ground to the engine and use aux ground straps on valve covers and a large one to the frame.

Re: Can't catch a break
Ground your battery to the engine. Not the frame.
Make sure your ground straps from the frame are connected to the engine. Gary

The only purpose of those big cables is to power the starter while cranking. |

Re: Can't catch a break
I agree I also added a woven large sized ground strap and attached it from the motor mount bolts to the frame it is clean looking and requires a 6-8 inch strap. Glad to hear yo found the problem.

Re: Can't catch a break
I have it to the frame and an equal size cable coming from the same ground point to the engine.
