Unilite shutdown

Response to Unilite Question

It is possible that you blew the surge protector, but unlikely. I think you could check it with an Ohmmeter for resistance and it would tell you.

More than likely, the module is going bad. FYI, I would fire it up, run it for a while, then check voltage at the pos side of the coil. If it is over 12V, you are likely overpowering the module on the back side (through the distributor)

If it is the module, going with an Accel points eliminator or Mallory E-spark is cheaper

Here is a link to the power filter

I will tell you though, I have never seen a filter fail, and I haven't seen a need for a filter. It has almost always been a problem with too much voltage to the coil when a Unilite fails (although 8 years out of it isn't bad, some MSDs seem to be failing out of the box lately)
