I have been trying to figure out how to make the alternator light work properly but so far no success
I have the New Vintage 7 LED indicator panel and have all the lights working except the charge warning lamp.
I have a 560 ohm resistor hooked up in parrallel with the light. I have one end hooked up to the brown IGN FEED wire in the Ron Francis harness and the other to +12 switched.
The light turns on when the key is turned and goes out while the engine is cranking. One the engine fires, the light dims a little but does not go out. The volt gauge indicates 14 volts so I believe the alternator is charging.
If I unhook the IGN FEED wire while the engine is running the volt gauge drops to around 12 volts, so I believe the exciter circuit is working.
I have heard that LED's don't function properly in this setup. Can anyone shed more light on how to get this to work properly with the LED?
