I just bought an ACCEL super hei coil PN#140003 and had it on my car for about 4 days and now everytime i put the car in gear at night my lights dim and the battery charge gets really low........while the car is idiling its perfectly fine but once i put it on D or reverse it almost drains the battery, is the coil drawing too much current for my stock alternator and battery 2 keep up?...im just going to put a stock AC Delco coil and see what happens, anyone know what else it could be?....the battery and alternator are pretty new .

the car is a stock 85 pontiac trans am,305 tpi,Automatic, only thing it has is the accel super coil and accel 8.5 wires, any help is greatly appreciated thanks.
