AC dead short?
Hi John -
Say, just open up the breaker panel and splice a 50 amp service directly to the bad circuit. Now just follow your nose to the smoke and you've found the short ![]() But seriously, its hard to find a problem like this even when I'm in your bus. Are you anywhere near the left coast these days? Hows things?
