Bruno Mueller:
I smoked the ignition electronics on the Retrol Musa HM 01. No, it didn't smoke, but I had no ignition spark.
As a precaution, I bought replacement electronics a few weeks ago. After replacing the ignition box, the device is working again.
Everything in the ignition box is filled with potting compound, so nothing can be repaired.
Admiral_dk:
That is annoying :zap:
The potting can usually be removed using heat ....
The compound usually breaks down around 150-160 degrees centigrade ....
I use a temperature controlled hot-air gun and small screwdriver / tweezers, to gently lift the compound (epoxy) away.
Per :cheers:
