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. |

Ran into a few problems testing the front electrical system:
1) Headlights pop up and down and came on. I tried high beam and they busted. Lights still pop up and down normally but no longer turn on with or without high beam. Did I just coincidentally bust both bulbs or is there something else going on? No fuse blew. 2) Only the front lights are hooked up. Should both the side and top front lights come on with parking lights on? Are the side front lights suppose to blink with turn signal?, with emergency lights on? 3) Is the brown wire coming off the top of the climate controller necessary or just an additional ground?  |
