I got most of the wire harness tie-wrapped; this is a temporary fix till I get the harness tape.
I am debating in using tech-tubing which would dress it up a bit. I know the purest fans will not like that approach, but I will still tape it to dress the wires till I make my mind up.
The results was interesting, the earlier post where I replaced the lamps was way out there but that was not the cure-all for this problem. When I finished the harness and got the Speedo cluster installed (less the speed odometer cable) and the ignition switch put back in the dash everything worked as it should.
I then put the Speedo cluster into the dash and everything went TANGO-UNIFORM.
The (edited) flicking-cluck-fluster chicken (edited) ……..Gen Light came on!!!
Back to square one, checked connectors, checked even the fuses and made all the ground checks. What was weird was the brake light was dim and the gen light was same intensity. Both lights were not the full on maybe ¾ intensity. So fiddle & faddle around and around wiggle & waggle looking for the fail. The Gen Light was on….check and rechecked and triple checked…TU Gen Light!
I know that I need +12+/- volts from the regulator to pin-2 on the instrument housing.
I know that I need +12 +/- volts to the instrument housing on pin-6
With these two conditions met the light goes out as they cancel each outer out till a ground appears from the regulator.
With the engine off and on the floor leaning back against the car looking at my drawing and tracing the wiring again! Upon finishing my soda I started the car and everything was normal???? Started and stopped the engine 12 times all normal.
The next time this fails, I am in the process of making a pigtail for the instrument housing cable to check voltages. The cable harness is too short to get a meter on the back plane of the housing. With the pigtail I can take voltage reading with a couple of VOM’s and see real time voltages.
The one item that I might have a issue with is the fuel tank sender. This takes the common +12 volts thru a resistor & gauge to the tank float to ground. My luck the +12 will bypass the whole bit and spark in the tank and Boom……………….at least I will be doing what I like.
