i have a 1986 nissan pulsar, no ECU, just basic E16 engine. I've gone through 4 ignition modules inside the distributor. once the first one blew, the next one lasted 5 minutes. I had forgotten to put the di- electric grease on the back. The next one i put in lasted 3 weeks, up until yesterday when it blew again. The third one i put in, i gracoulsy lathered the dielectric grease on the back of it, and it lasted 15 seconds.
Note: these are used modules i'm putting in, because new ones are 250$ a pop. Any ideas?
