I am completing my restoration of my 70 challenger and have not yet "started" the car. In checking out the electrical, everything works great, but I notice that with "full" load under just the battery power, the "flashers" get progressively weaker as more circuits are brought on-line. With high beam brights, radio, and dome light on, the flashers will "blink" but are weak. They work perfectly with the headlights off. Would I expect a different result with the car running, or do I have a problem somewhere that should be checked out? Anyone know?
