If I connect the 12V battery (+) to the 2 red wires from the main wiring harness and the battery (-) to the chassis ground, will the electrical system power up when the ignition key is in the ON position?
The main harness is plugged into the relay board. Neither the alternator, ignition or injection harness are plugged into the relay board, but all the round relays are in place. By electrical system I'm referring primarily to windshield wipers, headlights, and lights. I want to make sure they work before installing the fuel tank and engine. |

My ignition switch smoked when I tried it without mounting the switch in the steering column. With everything mounted all seems to work. I'm guessing the steering column provides a ground for the ignition switch and turn signal stalk.
After the smoke I bench tested the ignition switch. There are no melted wires. I sprayed dry lube into the switch just prior to testing. I'm speculating the smoke was some of the carrier liquid flashing off. I ohmed out all the fuse contacts. Could I have a defective high/low beam relay? The fresh air blower works with the ground wire disconnected. I'm wondering if the wire is just an additional ground and the fingers are actually grounded through the mount. |
