Hello,
I would like to hear from anybody who might have a favorite brand of mini starter. I have a big block and am using the common mini starter. It has failed after only a couple hours of use. It's a brand new motor, just getting tuned up and debugged. The starter was brand new and working fine. But then I was doing some tuning, ran the engine up to temperature, and shut it down. Tried to restart and heard only a click. No audible effort on the part of the starter to turn over.
I am running TTI headers, so the closest header tube is perhaps 2 or 3 inches from the starter. I am also using a heat wrap around the starter. The engine is a 493 inch big block, so it does put out some heat.
I pulled the starter and find the solenoid action is quite weak. Not enough to bring the Bendix drive forward and engage the starter. Note I applied 12v to the solenoid terminal and grounded the starter itself for this test.
I am surprised the unit failed, as disassembly reveals no apparent damage or broken connections. Wonder if the heat wrap was a mistake? Could that have held the heat inside the starter and cooked it?
In any event, I will need a new mini starter. I would appreciate any recommendations on a quality vendor, versus the generic Rock Auto model. Thanks.
