I have a 6.0l bored and stroked on a run stand fitech ultimate FIF-71007 and holley mid mount accessory drive. I put a high torque starter on it and starter engages but won't disengage.Anybody else have a problem like this

How is it wired up?

Full Power

The 8 mm solenoid stud goes direct to battery Positive.
The 5 mm terminal gets (momentary ) positive 12 volts from start relay- Takes a pretty stiff amp pulse to engage, if battery voltage is low, or IF main positive feed to the 8 mm stud is undersized, or corroded, the solenoid can attempt to draw even MORE amps than normal, and CAN weld the starter relay contacts together. I suspect your test stand battery and/or wiring is insufficient.

exactly as you stated,I tried a different starter got the same results.I will try a new battery later to see if it changes.

My starter issue seems to be alinement problem it engages the flex plate and rotates the motor but only disengages half way.tried shims but still gets stuck
