So I've read just about every forum I can find about wiring a drum switch to an electric motor, and I did one successfully years ago, no problem. Now its a problem. I'm trying to wire up a ventilation fan in my small fab shop out back. The thing is, I'd like to make the fan reversible and I know it can be done. I got my hands on an old attic fan, went down to grainer and got a new motor and drum switch, wired exactly as the schematic shows and I'm having trouble.
The motor works, even changes direction like it should when you flop the lever over, only the motor starts to smoke in about 10 seconds or so. I can wire the motor up direct without the switch and it works fine. With the drum switch, not so much.
I've read on some other forums about it and can't seem to solve my problem. Also seems like some guys get beat up pretty good about asking this question since, apparently, its been covered a time or three across the inter web.
Anyone interested in giving it a shot and seeing if we can work this out? I'll post all the details you need if there are some takers here.
Thanks!
Ryan
