Have an old Onan Generator (m/n 15HQ-3R/1374F) made in the lat fifties.
The Adj. power resister in the voltage reg. quit working, sending the out put voltage to around 350 vac.
It don't sound real good at that voltage.
Have all the manuals (with blue print wiring diagrams) for it, but all it shows is a dotted line around the "voltage regulator".
This did happen some time ago and after "Sandy" I'm keen on getting it going again.
I did get to talk to an Onan rep. and according to what little he could find out, that resister is 1200 ohm, 50 watt.
Can not seem to find one on the web that reasonable or close to that rating.
Today I got the idea of soldering across the bad spots of the resister. Had to use the biggest iron we have. The little 40 watt would not do. And still the solder ain't stuck to good, but I can't pick it off. Just not flowed out.
Measured the resistance, and it's at 1600 ohms or so. Put the adj. back to about to it was before, and it is running at 220v.
I'm iffy on 1) whether or not the solder will stay on.
2) questioning the 1200 ohm, 50 watt rating. Don't know what to look for now.
Is there a chance that a electronic voltage reg. will work and where would I find one?
Thanks in advance, bart
