I was recently left stranded on a busy down town street only to discover that my ignition coil primarys had developed a direct short across the + and - terminals which I believe subsequently took out the CD unit. I no longer have any positive voltage arriving at the coil but I have voltage on the red/white feed line to the CD module. The first thing I did to troubleshoot is disconnect the coil from the circuit and check for ignition voltage to the + side of the coil, then after confirming that there was no voltage present I removed the coil from the vehicle and applied voltage to the coil directly and it was then clear that there was a direct short across the terminals. If the CD module is in fact dead is it repairable or does anyone recommend a replacement that works well MDS possibly?
Is it normal that the coil could cause this damage to the CD or could it be something else?

Does anyone know who stocks a controller in Toronto or anyone want to sell one?
