After I put my engine in recently, I discovered that my alternator wasn't charging my battery. I used Wes Vann's excellent techref article to figure out how my internally regulated alternator was wired wrong. The alternator now keeps that battery charged. However, my generator idiot light acts opposite of how it is supposed to - i.e. when the ignition is turned to on, the light is off and when the engine is started the light comes on. This weekend I replaced my heater core(haven't had one all winter...). After reassembling it, I turned the ignition to on and tested the blower motor on all levels. After running it on high for less than a minute, I started to smell the wonderful scent of melting wiring. I turned the ignition off and disconnected the battery. Soon a lot of smoke was coming out of the top of the dash. I ended up pulling the dash out. I found that the brown-white wire from the ignition to the firewall block had completely melted. This wire meets at the firewall block with the brown wire from the gen idiot light. On the engine compartment side of the wiring, this is the brown wire that formerly went to the voltage regulator. Wes's article said to jumper this to the dark blue wire at the voltage regulator harness. The dark blue wire goes to the alternator to energize it. I have this dark blue wire connected to the terminal on the back of my alternator with the 'R' beside it. I have the terminal with the 'F' beside it jumpered to the battery post on the alternator per Wes's article. I replaced the brown-white under the dash with a temporary wire to test things out. Since I don't know very much about electronics, I switched the wires on the alternator terminals to see if that was what fried my brown-white wire. The alternator apparently wasn't energized because it wasn't charging. So I switched the wires on the terminals back. After I replaced the brown-white wire, the headlight bright idiot light now acts opposite of how it should and both turn signal indicators stay on. Does anyone have any ideas why the gen and bright lights are backwards and the turn signal lights stay on? Thanks.
