Re: J-10 delco alternator question
Yes, the lighted switch is only on when the ignition in the run position and engine off. I've done some searching on the other boards and found that my lighted switch acts as a crude idiot light. (Later j-series have no idiot lights). I scrounged up a red dash light so I'm going to put that next to my aftermarket voltmeter and do away with the switch. The #2 wire is on the battery side of the starter solenoid, so I'll leave that where it is. There seems to be a wide range of opinion where this #2 wire should go. I keep hearing battery post, solenoid post, horn relay, or looped to the Bat terminal on the alt. At this point, I have the wiring figured out.
As for the sparking, I tried 2 spare delcos I had lying around and it still sparks. The factory manual has some in-depth info on the delco and it says there is a negligable discharge rate at the across the R2 and R3 resistors. Is this what I'm seeing?; maybe there's nothing wrong. This is the only rig with a delco. The others have motorolas and there is no arcing when the batteries are connected. Thanks
