Guest SLH Posted August 16, 2013 Share Posted August 16, 2013 I am working on a 1955 T-Bird with a 6 volt system, the headlights will start flashing after a few minutes, I am assuming the circuit breaker is cycling, any suggestions on amperage draw, wiring, additional checks that I have overlooked, corrections that may fix this problem would be greatly appreciated.

61polara Posted August 17, 2013 Share Posted August 17, 2013 Circuit breakers will wear out sometimes. I would replace the headlight switch. The breaker is internal in the switch. Link to comment Share on other sites More sharing options...
miker98038 Posted August 19, 2013 Share Posted August 19, 2013 Dave is probably right, but if you have an ammeter handy, I'd check the draw from the switch to the headlights by disconnecting the headlight wire at the sw. There's always a chance there's a high resistance ground fault on the hot side, and the new sw will do the same thing. Ammeters (dc) don't care about voltage, and you don't need to worry about + or -, your just looking for the number. Wattage of headlights divided by 6 for volts, should give the amps draw.mike Link to comment Share on other sites More sharing options...
