67 Camaro Charging problems,,

[k9ulan]

I have installed a new Classic auto wire harness in my car..every thing works..accept i have a gen light on..im not sure if its charging or not..dont run it much.still in the works...the car runs with the batrtery unhooked.so i know the alt is puttting out..just dont know if its charging or not..the alternater is an internallly regulated..as per the new wiring system..any thoughts..?The ALT HAS A PLUG ON TOP WITH A BROWN AND RED WIRE, AND THE BIG TERMINAL IN THE BACKwith the hot and the little red wire going to the plug..something else..the gen light stays on with the plug is unplugged from the alternater, and burns dim with everything pluged up and ignition on only..., but bright when car is running..

It sounds as if your wire harness is set-up for an externally reg. alt. and you're trying to use an internally reg. one. You are most likely running off of battery power only. -Jabin
