or 115v in the son's 69 Globetrotter. He reported the power cord plug was smoking hot. So I started troubleshooting.
All four of the breakers were on, not tripped. Main, converter, AC circuit 1 and AC circuit 2.
I found the 115v AC wires going into the transformer of the converter are dead shorted. Seems like the coil has melted down, although it doesn't smell like a shorted electrical device (e.g. motor). This converter is not a Univolt.
So if I have continuity (1 olm resistance) between black (hot) and white (neutral) going into the old converter. Should I can start shopping for another one? I'm not going to power up until I understand this.
I also found the male plug on the end of the power cord to have loose spade connectors. It is a plug that has molded rubber around the spade connectors and round ground prong. I cut it open and found the "swaged" wire ends to the spade connectors were loose. That may have generated a lot of resistance and cause the plug to get hot. A classic loose connection. A lot of fires have started that way.
Is my converter shot? I'm assuming there is a rectifier in there somewhere that might be confusing me.
