fan diodes

I have the same fans and diodes from Precision Proformance, I put them on last fall. Mine came with a wiring diagram that I looked for but did not find. My original harness has 2 wires to each fan. One is black and the other is black with blue. The red wire on the motor is connected to the black wire on the harness and the motor black wire is connected to the black/blue wire on the harness. The diode is inserted in the connection to the black wire on the motor. The diode is not attached to the chassis. One end of the diode has a tab which I used to connect to the harness. The other end of the diode is a threaded post to which I attached the fan wire.

What amp rating diodes are you using?

Vendors have the diodes.

SOBill's list shows fan diodes as:

http://www.nteinc.com/ Diode NTE5940 rated at 50V and 15A diodes for isolating fans

Diodes on 2511 have the red merriah wire attached to the chassis (ground) with the black merriah wires running through the diodes to the harness wiring. My diodes are mounted in holes drilled in the fan support structure with fiber insulators to isolate them from the chassis grounded system.

Thanks Larry. Since installing the Meriahs on my car, I get the occasional run on. Pumping the brake pedal will kill the engine.

When I installed the Meriah fans (no diodes) on my car, I also got run on. After I installed the Mosely (sp?) Kit the run on stopped! Good Luck...Curt
