MG MGA - Coil
|Firstly,happy new year to all.|
Just finishing off a few jobs before fitting the body and trying to startup.However I have not fitted the wire between the coil and dizzy.What gauge does this have to be,and what amperage?
|hi Steve just had a look at ours and it is only light weight/ cant help on the amperage , check out Barney the Guru he is sure to be right , we are near to Sidmouth , how about you ? good luck .|
|If the coil were 3 ohms then ohms law would suggest that V = I x R|
Or 12V divided by 3ohms equals 4amps :)
From memory I think the coil resistance of a non ballasted coil is around 3 to 3.5 ohms so 4 amps will be OK. No need for heavy gauge wire just select the same gauge as that in the distributor.

|Only 4 amps nominal, but it sees more current at higher voltage for a few milliseconds at a time when the points open. 18 gauge is fine, and is the smallest wire you should use for any automotive application.|
|sorry should have said, in the UK we would use .75sqmm for that kind of current. 1sqmm would be more than ample if that is what you have.|
