Aright guys, I must be dumber than I thought when it comes to electrical systems... somebody help me out here. I wired up a manual switch for my fan but something isn't right. I keep blowing fuses (I've gone up to a 30 amp), so I tried briefly wiring the switch without a fuse. The fan barely came on that way and the wires going into the switch got hot after only a second. I unwired the switch immediately, but something is obviously wrong in my circuit.
The manual switch has 2 connectors on it. I connect one to the 12V power source and one to the fan motor wire. The fan motor is grounded from the factory, so I didn't think I'd have to ground the switch. Is that wrong? If so, how do I ground the switch with only 2 connectors on it?
I've tested the voltage coming from my ignition power source wire, and it's a good 12V+. I tested the resistance in the fan motor wire, and it's less than 1 ohm. So I don't think there's a problem with either of those wires. Do I just have the wrong kind of switch?
