I put the new alternator in today, the Gen light still dimly glows.
I pulled out all the fuses and broke the on to the instrument panel, replaced it with a 5amp. With all the fuses out the gen light was full bright on. This is because the regulator is giving out 12volts when running and finding a ground.
Put all the fuses in and still the same problem Gen light glowing
Next to the last item I changed the lamps out to the proper bulb a #194 for the parking lamp and the Gen light.
Gen Light is out?????????
I am lost to why.
I know that when the regulator is working, it is sending 12 volts to the lamp. The instrument housing gives 12 volts to the common buss. The two voltages cancel out each other and no lamp is lit. When the regulator fails, it gives a ground and lights the lamp.
These lights and gauges do not pick up a ground off the instrument housing.
This is at idle.
1. The Voltage Regulator or Gen Light (brown wire) is putting out 14.26 volts to pin-2 and has a wire to the ignition switch. 2. The supply voltage (pink wire) pin-6 is at 14.06 volts. 3. Parking brake/brake light (tan wire) pin-3 gives a ground. 4. The oil pressure (blue/white wire) pin-5 gives a ground. 5. The temperature light (green wire) pin-8 gives a ground; it has a wire to the ignition switch. 6. The fuel gauge (tan wire) pin-7 gets its voltage from pin-6
I do not have the Temperature sensor or the oil pressure sensor lamps hooked up. They are tied back at the motor. I can give grounds at the leads and light the lamps except the temperature lamp. I can light the lamps at the connector at the back of the instrument housing.
Well I got to think on this a bit. I will put back everything and see what happens.
