Hi from the U.K.
I have a U.S.A. 120VAC 60Hz ignition coil (made by Carlin Combustion, model 45000 proX… the data sheet says the high voltage secondary coil is mid-point grounded).
I have been powering the coil from a U.K. 115VAC 50hz supply (my supply has one leg of the transformer grounded to earth so 0-115VAC).
it’s been working ok for a few weeks but has started tripping out the circuit breaker.
there’s a number of possible reasons why, but first I’d like to eliminate the possibility that my ‘end-grounded’ 115VAC supply isn’t burning it out!
I understand America has two voltage option fir your supplies, you have a 240VAC centre-tapped transformer with two hot wires (red and black = 240V) with a white neutral centre-tapped from the secondary transformer and grounded to earth (so red + white = 120VAC and black + white = 120VAC)
so my UK supply is effectively the same as using your red and white cable. What I’m not sure about is whether the ignitor’d primary side is also centre-tapped in which case I would be shorting out one side of its primary coil and burning it out. But If the ignitor data sheet only means it’s secondary coil is mid-point grounded I shouldn’t have a problem, no?
Any suggestions?
Cheers
