SR71X starter install issues,

[beast02er]

I have installed the BOSCH SR71X starter (straight bolt in as far as I have found) and when I went to start the car, the motor just spun freely. I have untightened, retightened, unbolted and reinstalled the motor, and it still does it. It seems like the gears aren't in contact....so is there some modifications I need to do?

Thanks,

You sure its not an issue with the wiring? The posts are a bit different from a stock 02 on the small starter, so you're probably not engaging the solenoid properly. I wish I could recall the proper wiring... or if you give me a minute, ill walk five feet over to my car and look.

oh wait a second, do you mean the large body SR71X or the small body one?

I have the small body.

The only wire I wasn't sure about was the smallest one, hooked up to either of two prongs, I hooked it up to the one closest to the intake ports (like it was on the stock 02 starter motor)

that small wire connects to the other set of connections, should be able to see he area where you connect it.

It needs to be hooked to the bottom prong instead.

So the wiring being wrong would cause it to spin freely, but not engage the actual gearing? Seems odd that if I had the wiring wrong it would still spin.

I will try tonight though

Yes, you were triggering the starter motor by itself. You need to instead trigger it thru the solenoid, which which will push the gear (pinion/bendix?) out to engage the flywheel.

Brilliant!!!

Makes sense
