I picked up this non running rust bucket for next to nothing. It’s a universal motor. Pulled the stator and checked the leads off the stator as I would with an AC fan.  Not sure that’s the right way as every universal fan I’ve had has ran. Showed zero but when I tested between a lead and one of the spades that attaches to the brush post I scored a 38. What is the proper way to check continuity on a universal ac/dc?

So I went ahead and checked the other pair, the lead on the front and corresponding spade that goes to the brush assembly on that side. It was also at 38 ohms. So I think that might be the way to check on these. At least I hope so as I’m moving on to cleaning/stripping/resurrecting the old rust bucket. Hopefully, it’ll be more than a decoration when I’m done!

Good luck with the new resto, Dave!
I always get mine in working order, then go for restoration disassembly. No surprises when put back together. My recent 17666 purchase is a case where if I had not spent several hours getting it in running order, I would have had a non-running restored 17666. Fortunately I found the stator was bad(I mean I couldn't even dig out the problem bad) and found a suitable stator to continue the resto with. :)

Thanks Alex. That’s certainly my intent. I’ve got $10 in it so if it runs, I’ll be a happy camper. From there, it’s cosmetically although that’s going to be an uphill battle so I’d just as soon not do too much till I know the stators good. Do you know if how I got my numbers is the way to check it on a universal?

Your test results indicate that the stator is okay.

Thanks Mark. That’s great news. I was trying not to get my hopes up given that it wasn’t running and looked so bad!  Had my share of burnt stators.

Well, once I found out the stator was good I set out to clean it up as best I could.  Plugged it in, nothing.  With some advice from Austin Ko I realized the brushes were not making contact with the commutator as they were about gone.  I knew they were on their last leg.  So inserted a short piece of wooden chopstick between the cap and spring just enough to push what brush was left up against the commutator and, lo and behold, it fired right up.  New brushes and spring/shunt assemblies are now on the way.  Still need to come up with a shoulder screw for the oscillator but have seen a couple ideas online here as to making something short of original work.  Other than that, happy with how my little $10 rust bucket turned out.

Looks great David! Gotta love when rust is turned into gold(or brass and steel in this case)!  :clap:
