I swapped starters today because of a slow start heat soak issue. When complete no crank. Everything else works.

I swapped the old starter back in, same problem. So I reinstalled the new one.

Vats was bypassed via resistor long time ago. Security light is not on when attempting to crank.

I bypassed the start enable relay, to make sure the relay wasn't bad.

I bypassed the clutch switch.

I pulled the lower harness with all the starter leads up through the engine bay. I tossed all the loom and inspected. Found a spot in the purple "s terminal" wire that was pretty beat up, and another previous repair. Everything else looked good. Repaired purple line and reloomed/ installed.

I have 12.4 V at the hot lead to the starter.

Under "crank" conditions I have 12.0V to the hot lead and 11.8V to the "S" lead at the solenoid.

I've spent half the day running through similar threads with no solution. What the heck am I missing here?

 

Nevermind....It was a bad new starter.

 

For future reference, what brand was the defective starter, and from whom did you buy it? Was it new or rebuilt?

 

Reman, ultima. Orielly.

Funny thing is I ordered a new AC Delco from rockauto for the same price....now I just have to wait a week.

 

thnx

It's tough to find a reliable remanufacturer these days.

 

I came in here to mention not ruling out the new starter as bad. Sucks that you cant count on new parts. I had a new alternator and a reman starter be bad out of the box.

 

(sigh)

The quality of just about everything has gone into the toilet over the last several years as companies do whatever they can in order to wring the last possible cent of profit out of consumers. Auto parts are no exception to this problem.

The only option is to rebuild the component one's self (starters and alternators aren't very complicated devices), but that brings up yet another issue---finding quality repair parts. Used to be, OEM-level bearings, bushings, contacts, diode bridges, brushes, voltage regulators, starter drives, etc. were readily available. You'd think in this day and age the availability factor would be even better due to the interwebz, but that only leaves the door open to profiteers selling cheap-a$$ Chinese junk. And trying to get something replaced under "warranty" from some of these gonifs is even worse.
