I tested the battery tonight and its putting out a charge. The ABM from what I can tell, has a new engine harness, MSD, JWest fuse panel, a blasted interior, H4s with relays, and a newerish stock board.
With nothing "on", hooking up the battery seems to "arc" the front headlight motors, or something up front. Transmission ground is on, battery (-) is ground, front turn signal grounds are attached. Nothing at the ignition, although with light switch "on" no "arc" but no light. Ignition switch seems loose. Wiper handle is very loose. I bought a color diagram, but I'm color blind. Is there a method to trace electricity step by step from the battery out through the harness, into the dash, and out to the lights? I need to get this ABM on the road! |

Some more testing with the inline fuse to ground. The front marker lenses come on and the headlights pop up and stop. Putting them down manually makes them pop up again.
Turning the headlights on does nothing but the rear lamps turn on. Fogs don't turn on. No turn signal, but the marker light gets brighter. Ignition on: no change. I'm wondering if my ignition switch is busted or not plugged in right. Tried a quick crank, no crank.... Left it on for 2 mins or so, no burning no fires.... |

Some more testing with the inline fuse to ground. The front marker lenses come on and the headlights pop up and stop. Putting them down manually makes them pop up again. There is power going to the "turn on the headlights" circuit. If the lights go up again, that means there's power still to that circuit. The switch is mis-wired, it sounds like. Headlight motor circuit: - If power is applied to the "raise the lights" terminal, the lights go up until the "light is open" microswitch inside stops them. If you crank the light down, as soon as the microswitch gets opened up again from the movement, the motor will run again and keep running (through the "light closed" position) until it gets to the opened position again. - If power is applied to the "lower the lights" terminal, the lights will go down until the "light is closed" microswitch inside stops them. If you keep the power on to that terminal, and crank the light partway open, the microswitch will eventually open. Then the light will open up the rest of the way and continue until the microswitch again stops it--when the light is closed. --DD |
