are you going to send the seller a few bucks now that it's got some functionality? Who am I kidding....that never happens.

I think you have nailed it my friend. Stay tuned.

ok, just watched a video where the commutator was causing too much resistance. I'm going to clean that up.

I did everything suggested. It's not as bad but still slow and an immediate weird smell and white sparks flying inside. I'm beginning to wonder about the switch.

I'd say it's nearing 25 years old.

Checked the bearings on both ends of the motor and they turn freely. Brushes are good. Commutator segments are clean and isolated from each other.

I have an old Craftsman 1/2" electric drill I bought when I was a teenager. I was just using it and had noticed the last few times that the motor was having a harder and harder time turning. Well now it's at a near standstill. Yes, I've smelled some warming up but stopped. I wouldn't think...

Fan it is

i think i found the answer. I'll test that fan now.

I bought a used battery charger. the power cord is showing a short. So I disconnected the power wire from the charger and the short went away. So now move on to the internals. I've eleminiated the timer switch and the isolator. Now to test the transformer. My question is on the primary...

Here's the next question. The dual stage pump, it's the low pressure rod which has failed. Can I remove the rod (might as well leave the piston in the bore i guess and hope it doesn't work it's way down) and just run the thing with the high pressure piston?

Campbell Hausfeld 80 Gal Compressor Pump model: FP070000AV Motor Number: BM74 I verified that the rod was knocking against the crank. Do these things not have rod bearings?

50 Amp breaker fixed the issue. Thank you very much. New problem. Sounds like a rod is knocking....loud.

Yes, the loud hiss does happen when the compressor shuts down. I will have to look at the wire size and get back, however I did myself install that breaker box and I 'usually' go overkill on the wire gauge. The breaker is Eaton BR240 40Amp. Model Number: BM74 Brand: Emerson Description: OEM...

This is a possibility I did not consider but should have. Given the proliferation of Chinese goods in our country coupled with their very questionable quality and my refusal to buy 'Made in China', it should have been a suspect early on. QUOTE=redmondjp;4615463]I'd say that you have a...

I think you nailed it. Today when it happened again I listened very closely. The circuit breaker did trip, it just did not flip all the way to the 'OFF' position.

Campbell Hausfeld 80 Gal Compressor Pump model: FP070000AV Motor Number: BM74 Not every time does it fail to start. Just sometimes. It does not trip the circuit breaker. To start it I go to the circuit breaker, turn it of then back on. Motor capacitor is within spec. Other than the...

I've got all of the equipment except for a single bottle sized dolly. However, you're correct....lugging that beast around (if I'm even allowed) the yard would be a giant PITA. I got plenty of funny looks the last time I went out there with an umbrella (it was 100 degrees that day)...I'm sure...

I've been looking at battery powered 1/2" impacts. Very costly. Could I take a high pressure air cylinder (like used for welding and holds thousands of PSI), put a regulator on it and then power a traditional 12" wrench. Would come in handy at a salvage yard to remove control arms.
