    So I'm in the middle of a restore and ran across a bad coil. I found a replacement and it's kinda weak. I usually throw my coils in a ultrasonic cleaner, blow them out with air and let them sit for days to dry. Seeing this is the last issue before I put the playfield bacK in the cabinet. I was thinking, ultrasonic cleaner, blow it out then sit it in front of a hair dryer on high heat for 1/2 hr

    Wipe it off and install it.

    Get a new coil on order, and install it when it arrives. Or, clean another used coil, clean it, and install it once it's had time to dry.

    That's what I do, ultrasonic cleaner, then use the air compressor with the air attachment and that seems to work great. Also replacing the coil sleeve is better than reusing the old one. Then I put the label back on with a dab of crazy glue and it's good as new.

    I ultrasonic, blow it out, soak in 99.9% alcohol, blow out, run under heat gun until windings get warm to the touch. Maybe over kilbut I have never had an issue. ::knocks on wood::

    I think people get overly nervous when talking about electricity and water. I suppose that is a good thing. The only exposed conductors on a coil should be the lugs, diodes and a small part of the wire. I would think it would have to be seriously wet to bridge those contacts. I'm more worried about rust than electrical issues.

    I commonly submerge the coil in the ultrasonic, dry off with a towel and blow out thoroughly with the compressor. By the time I rebuild the assembly with my newly printed coil wrapper it's completely dry.
