Its Len p5b XYW 188 ,the car is just about ready for booking in for an MOT, and sods law.The ballast resistor near to the coil is overheating,and the voltage is dropping to abouy 3 volts .I had a fault on the resistor itself ,with a bad connection on it ,which I thought I had cured .The car cut out on tickover and the ballast resistor started to smoke so quick turn off.I havn`t had any luck in getting a new resistor.Can I change the coil for the later type and is there any rewiring to do .Any one help

Len if the ballast resistor is getting hot it sounds more like after it you have a fault After the resistor it goes 2 ways one to the coil the other to the coil balast shunt if it's getting hot it can't be Open Circuit there fore it looks like the coil SC to deck or a short in the wiring to the ballast shunt not an easy one if you were closer!!!!

It should get hot which is why is on a ceramic open base to allow cooling
