1970 Elky-Revisiting A Charging Problem
When I bought this car, the gen light stayed on dim all the time and went out if you exceeded 2k rpm. I repalced teh alternator for cosmetic reasons in the resto, and the voltage regulator with a Wells VR715, because, well, I always use them. The gen light now glows dim all the time now that the car is back together, regardless of RPM. I checked some voltages today, and here is what I found
At idle in park, 14.1v at battery, horn relay and orange regulator wire, and 13.1 at the Autometer gauge under the dash that is wired to a switched 12v fuse block spade
In gear at idle with lights on, 13.8v at battery, horn relay and orange regulator wire, and 12.5 at the under dash gauge
In gear at idle, with a/c and high blower and lights on, 12.8v at the battery , horn relay and orange regulator wire, and 111.0v at the under dash gauge
Last week, coming home from a cruise was the first time I'd had the ac/ going full blast and the lights on and I noticed the low gauge reading and the instrument lights were dim. If I shut the a/c off, the gauge showed an increased charging level and the dash lights got brighter.
The only thing out of the ordinary that I noticed is that the wiring diagram shows a ground wire attached to the core and terminating at the top regulator mounting bolt, which seems redundant.
Also, I have a pink wire with a black tracer coming out of the harness, attaching to a spade that exits the side of the voltage regulator, this is nowhere to be seen on the schematic. This spade is joined to the brown wire spade on the regulator by the same bar.
Any ideas? The differences in the schematics has me confused. BTW, these are in my assy manual.
It is a rare man who can count his own blessings and not mistake them for personal achievements.
