(1) Out of curiosity, I put a pair of alligator clips across the seal beam's low beam bulb element, I measured around 10.2 volts. At the same time, the voltage measured at the battery terminal is 11.9v. I have some significant voltage drop. So, I pulled out the schematic and started measuring the voltage of the headlight circuit from the battery terminal.
At the battery terminal -11.9v
At 40A fuse under the hood - 11.8v
At the big white wire under the steering column and above the fuse box - 11.4v (this is before the headlight switch)
At the red/ble wire (after the headlight switch at the steering column) 10.9v.
At the light - 10.2v
Which items should I look at first? Should I just forget it and run a relay and pull power for the lights directly from the battery?
(2) I'd like to replace the stock battery terminal clamps. I found a direct fit one from Autozone for the -ve bat terminal to the transmission. But how do you do the +ve (red) side? There are two large wires connecting to the clamp on the +ve side. But new clamp only have one large wire coming out of it. How do you connect two large wires there?
(3) There is a piece of cable connected between one of the nuts on the valve cover to the body of the car. Where do you find a good replacement? I found some 19" lawn mower bat cable but the pre-drilled holes seems to be too big.
(4) Am I wasting my time trying to fix all these?
Thanks for insights !
