My 86 Spider has a lightened flywheel and does not handle the AC compressor well, sometimes it even kills the motor. I have a great, smooth warm idle, so I would rather not increase my idle speed.
There are two Bosch relays under the hood that seem to be associated with the AC- wires have been cut from these by a PO, so I'm not sure of the proper wiring (or if they should even be there from the original dealer install). One relay is working properly for the electric fan at the front of the condenser, and I wonder if the other was supposed to tap into the coil and computer to alter idle speed when the compressor is engaged. Does anyone have a properly wired setup like this, or better yet, a wiring diagram?
If this was not the original intent of the second relay, does anyone have any suggestions for an idle speed switch for Spiders of this era?
Thanks!
Doug
