Generator light? Yes it will turn on for just a second if I have to crank the IGN a few seconds.
Not shiny bolts, I can clean them up, the VR grounds through it's legs correct? Yes it's on freshly sanded surface metal.
All of my gauges work, my clock does not, nor does my overhead lamp. I'll have to check on temp light.
I've done the F-3 alt test and it works. I'll try the light test sometime today. Thanks.
Is your car equipped with gauges or idiot lights? Is this an SS pod style dash? or a sweep dash? Sorry if I missed it in earlier posts. The SS light dash is in the attachment.
If your VR is mounted on clean metal it should be grounded sufficiently. There's a terminal on the bottom of the VR. It should not be grounded. If anything is connected it would be a one wire condenser. It's only job is to prevent radio interference.
Your alternator mounts and bolts should be clean at the mating surfaces. Your negative batt term should be bolted to a clean surface with clean bolts to the top of the alt bracket. The bolt should be tight. Sometimes they strip out, if this is the case, get a longer bolt and put a nut on the bottom side and tighten. The neg term can also be mounted on a bolt to the engine. The connector bolt and block should be clean and free of paint. If you really had a problem here, it would show up when you put a high load on the system like starting the engine.
More than likely your clock is toast. They wear out.
Dome light is powered by orange wire. It turns on when the other wire is grounded. It's on another circuit, we can mess with that later.
Did you check your fuses? Turn on the ignition and check for power at all fuses. The tiny "inst lts" fuse requires you to turn on the headlights and turn the rheostat brightness adjuster to the right just before the click. (I think if my memory is correct. I can check tomorrow)
****Check your GEN light operation. This will confirm or deny a closed circuit from the ignition switch through the gen light and out to the brown wire at the reg connector. Without this circuit, your alt will not produce power. Leave the connector connected to the reg. Turn the ignition switch 1 position forward to the IGN position. The light must be on and stay on if the engine is not running. If no light, turn the key off and slowly move the key forward and see if there is a position that the light will stay on at. Take it all the way to start. If there is a slight position where the light stays on be sides the detent IGN position, it tells us the IGN switch has a bad contact or is out of adjustment slightly.
Still no constant light? Remove the reg connector and temporarily jump the brown wire to ground. The light should light. If not, also suspect a bad connection in the bulkhead connector on the engine side of the firewall to the fuse box or burned out light.
