This started out to be simple (don't they all). I assumed I was going to find an open neutral.
The original complaint was that the garage lights were flickering (flourescent). I measured voltage at the panel and had 168 on one leg and 72 on the other.
I checked the neutral and also ran a "jumper" frorm the grounded water pipes to the nuetral/ground at the panel...same problem persisted.
The really exciting part is that for no apparent reason, the problem disappeared. I tried for over an hour to duplicate the problem but I couldn't. I turned breakers on/off, maximized the load etc. with no luck.
As I was getting ready to leave, presto...same problem. Then it went away after about 15 minutes and I could not duplicate it again.
I am operating under the assumption that since I ran a jumper from the ground rod to the neutral, that I have eliminated a poor neutral connection from the power company as a possibility...
Any suggestions?
Thanks.
