Thanks Mate
I have emailed Marcus from Rex"s Speedshop and he was quite helpful. I have ordered a second hand Ignition Module but I'm concerned that it will blow that one up too. Has anyone got any idea how the protection circuit works and how to test it? Below is a quote from an email from Marcus.
Its unlikely that part is available so it would mean I'd have to spend time looking for equivalents. I would need to know all the numbers, from the un failed item, to see if there is something available.
The other problem you might have is the protection circuit may have been damaged. When the transistor opens the circuit, the HT coil sends a 400 volt spike through the circuit. The transistor can't deal with this power surge, so there will be a circuit to protect it.
Any help would be greatly appreciated.
