Here's my problem. I installed a set of Auto Meter NV series gauges in my 69. I replaced a temp gauge and a oil pressure gauge with these new gauges and added a volt gauge. Everything is working lights and all until i start the car. Then the lights go out on the three gauges. The tach stays lite up though. I'm running all 4 (tach,water,oil,volt) of these through the same wire so i don't know if it's pulling to much once the engine is started or not. The weird part is if i go out and just turn the lights on without turning the key everything will light up. It's only when i turn the key on or start the car the lights to these three gauges go out..
Any info would be helpfull.
