I bought a Powermaster 9510 XS mini starter, for my 1970 Oldsmobile 442 with a 455 engine. The powermaster has 2 terminals. My stock starter has 3, positive post, run wire, and ignition wire. I was told that the powermaster should bolt right up, and work as the original does. So, the problem. I have 3 wires, and 3 terminals on the stock starter, and only 2 terminals on the new starter. Any suggestions? Thanks!!

 

Watch this :

 

It depends on what distributor you’re using. If it is not points and you have full battery voltage running to the coil, simply cap the yellow wire going to the coil+ terminal from the solenoid R terminal.

 

Thank you all for your replies, I now know that I need a diode on the run connection. Again, thank you so much!
