18 VOLT, RYOBI BATTERY CHARGER DOES NOT WORK --DISPLAYS NO LIGHTS WHEN PLUGGED IN.

My Ryobi P118 Charger stopped working with no charge lights.

It comes apart easily -- after you buy a T15 security Torx screwdriver. A 1/4" bit is too big to fit the hole in the plastic.

There was a gob of carbonized crude on the primary side near C29. I just cleaned that up with some 90% isopropyl and a toothbrush and dried it thoroughly with a hair dryer.

After powering up, it worked fine. There is also a fuse soldered in which you can check. Mine was good.

CAUTION: The Primary voltage was 145 volts on my charger so make sure it has been unplugged for 30 minutes to let everything discharge before opening it up.

Answering my own question, I opened charger & found a slow-blow fuse that had failed. Hardware store had only a 5 volt, larger body fuse than the 4 volt, smaller fuse I had removed. I figured that a 25% higher cut-out voltage should be acceptable, and bent the fuse holder assembly to hold and make contact with the larger replacement fuse. Voila. Immediately got my green & yellow bulbs to simultaneously light, indicating ??
