I have replaced my engine, dash harness and bought a new printed circuit for my 72 sprint cluster. After installing everything I can't get the bulbs to light correctly and the gauges temp, fuel register hot on the correct side, but they also show dim on two of the other post. The circuit has power through it. Some of the bulbs light and the others don't. The turnsignal bulbs light when the headlight switch is activated...any help...please
