My quicky starter test is to put the starter on the floor, hold it down with my foot, and apply 12v with a jumper cable. Little gear should jump out and starter should spin.
That's exactly what I just finished doing . When I woke up today (I'm working nights) I used my jumper cables and my truck (67s battery is dead) when I connected the power the solenoid activated and kicked the gear over but the starter motor wouldn't spin.im picking up a starter on my way to work today autozone had a rebuilt one in stock. I'll try to find time to put it in tomorrow and go back to trouble shooting things.
If you're not sure of the exhaust system, there are 2 nuts or bolts that hold the head pipe to the exhaust manifold that can be removed to separate the pipe. For short test sessions only!
I have a used mini starter on mine. Less weight, faster speed, compact, easy to repair. What's not to like?
