My retired neighbour asked me if I could take a look at the GFCI outlet in his garage, which he said would no longer reset. I probably didn't need to, but I replaced the 35 year old outlet with a new one, and when I turned the breaker back on, the GFCI tripped. In these older homes, the breaker panel feeds the garage GFCI outlet, and there are two downstream loads - another outlet in the garage, and the outlets in each of three bathrooms. I disconnected the load going to the bathrooms and the GFCI stays set, and both the GFCI and other garage outlet are working.
As for the three bathroom outlets (two upstairs, one downstairs), there is nothing plugged in. So here's my question: what kinds of faults are common in this situation, and what is the best way to figure out the problem? I'll obviously have to pull the bathroom outlets out of the boxes and look for obvious things like moisture or arcing, and I suppose I could just replace all of the outlets. Would resistance measurements between the hot, neutral and ground help zero in on the defect?
Thanks!
