No spark | 356 Speedster, 550 Spyder, Replica, Automotive Community

My IM has been running since before Christmas. It will crank without problems, but won't fire. I've confirmed there is current to the positive pole in the coil. I purchased a devise that plugs into the spark plug wire and connects to the spark plug. When current flows the device lights up. I tested the devise on my Tracker with success, but get no light when hooked up to my IM. What else can I check to determine why I've not getting spark?

Are you running points/condenser, Compufire, or Pertronix? If points/condenser the condenser may have failed. Or the 12V+ wire inside the distributor may be shorting to the distributor body. If it's a Stock VW distributor rotor, they have a resistor inline from the center contact to the rotor transfer; if the resistor pops, no sparkies. Or the coil high tension lead may have an open between coil and distributor cap (the silicon ones can burn out). Or the distributor cap may be cracked and shorting internally. If a solid state triggerr maybe that's gone bad.
