Help Needed:Wiring diagram for ingersoll rand 7.5 compressor motor start& run capacitors

We have ordered replacement start capacitors for our Ingersoll Rand 7.5 compressor motor. The problem is that when we got the motor, the capacitors were already disconnected from each other and the motor. I have looked everywhere I could think of online and rephrased my search as many ways I know how but no luck so far with how to install them back.
Please help!!!

Image of wiring?
by: Anonymous

I cannot see the image of the wiring solution on the comment here. Is there still a copy available? I'm trying to help wire the the capacitors on an Ingersoll Rand starter (PN 22095277). There are 5 wires and they blew off when the caps blew so we don't know how they should be wired.

Cap wire...
by: Doug in

Luke, that wire may go to that cap, but it's likely disconnected for cause. Maybe check the cap first and if OK, try connecting it.

CAPS vs capacitors
by: Doug in


An individual unit may have different caps due to using a comparable, but different motor.

You need to ID your motor.
