Re: Headlights and electric cooling fans problem
You can make a jumper wire to go from control side power to switched side. This will allow you to jumper the relay without cutting the harness. Dont know if that is what you were planning to do, but just wanted to make sure you knew you didnt have to cut anything. This should be able to tell you if the relay is the problem, or if you have a voltage feed problem. If the headlight does not flicker, I would verify good ground on the control side of the relay block. (ohm it out. 0-3 ohms is what it should read depending on the run length of wire to ground.) If this is good, you probably have a bad relay. Also, as to the fans, if you want them to shut off when you turn the car off, just make sure they are on an ignition voltage source instead of a battery. I dont know how you have them wired in, as mine are switched by my Holley system. Details on how the fans detect temp, and how the circuit is currently wired in would help alot.
