I've gotten myself into a predicament. I have a 110V single-phase Logan lathe which needed the reversing drum switch replaced. I got the old out no problem. I purchased a Dayton 2x440 drum switch with 6 contacts. The switch contacts are laid out as shown in this diagram I found on this site (I know this is a Dayton and not a Furnas, but the terminals and bus bars are set up the same):
The motor is very likely the original, it has 4 wires coming out of it.
In trying to rewire it, I have it so that off and forward work fine, but if shifted to reverse the breaker pops. I figure I have two wires that need to be switched, but which ones? What troubleshooting steps can I take to track down the problem?
