Eileens 79 Corvette resurrection. It survived 1450miles on Power Tour
- Thread starter ktmoutfront
- Start date
Rockers are rocking.
That's what is wierd. It turns over with a 6" long wrench without the plugs in it. Does not feel like it is tight. And I forgot to mention that the converter is not hooked up now. Had the same thought about the transmission.
Checked that also. Has the correct crealance. Does not sound funny either. When they are too tight, they whine.
So turns over with a wrench but not the starter. 2 starters, tried different batteries, and different cables?
But if the engine rotates with a wrench, it should at least move the engine. Plugs out it should spin it super fast.
So not being there, armchair mechanical says starter issue. With both starters. Either some weird interference issue, sounds like you can eliminate the wiring issue.
It still sounds like something is at issue with the starter. What that is I don't know.

That's what I am leaning towards also. I done tried multiple of everything. That is what is so strange.
Ground?
Put a voltmeter on the battery while cranking. If a healthy starter is loading down mechanically it will bring the voltage well below the normal 12.5V resting voltage. If it doesn't drop significantly, you have a wiring problem (could be inside or outside the starter).
If the battery voltage doesn't drop below 9V, then try measuring the voltage right at the starter lug (downstream of the solenoid) to see if it is dropping there. This will tell you if your problem is caused by crummy connections (ground included).
If it's not dropping at the input lug, the starter is not trying very hard and you should look at replacing or rebuilding the windings. Or just buy another one.

All grounds are clean and tight. And I bypassed all car wiring and hooked directly to the new starter.
The batteries were charged over night and I going to check loads later today.

I was going to suggest a remote starter to eliminate the car wiring but you already covered that. With it being so odd, I would be tempted to run pos & neg cables straight to the starter and see if that makes any difference. Then the starter would be completely isolated.
Been there, done that. 1/0 cables 4 feet long. Both positive and negative. Negative to a starter bolt.
so in summary.....you can turn it over by hand with the plugs in it AND it's not spinning fast via the starter with the plugs out.
tells me it's the starter, wiring or lack of juice.
double up some battery's or use a charger on boost.

To Clarify. Turns over normal by hand with the plugs out. Never thought to try it with the plugs in. That might be telling.
oh I thought you did? Well if you haven't I have some other interference theories......
Voltmeter.
Say it with me...
