Low Amps When Trying to Start
So, I have replaced the Starter, Battery, and Cables a few times each since people keep telling me that's the problem, but it never fixes it.
Basically, whenever I turn the key to the start position, it gets such low amps that the starter can't crank over the flywheel. It trys, but fails to get even one rotation out of it. I had the starting system tested, and it said I was working with something like 30 amps on start from an 800cca battery. I have cleaned every contact known to man on the engine and body, including the big 3.
Whenever I cross the starter posts with a wrench, I can get it to turn just fine, like nothing was wrong with it. It also starts perfectly when attached to another car via jumper cables. Originally, it only had this problem after driving for a while, and even then, it didn't happen often. Then it gradually progressed to the point where it happened only when the truck was hot or had been run. Let it sit for ten, and it would start fine. Now, it won't start at all. I have to put my key in the run postition and start it by arcing the starter.
Anybody have any ideas? It's been like this for months now, and I can't get anywhere with it. Any help would be appreciated.
