Generator doesn't make Electricity

Jim Ranking is right on about 26K (26,000 ohms) being too high!

You need to check the slip ring to slip ring without going through the brushes.

Resistance should be in vicinity of less than 40 ohms and most like in vicinity of 26 ohms or less! Also check each slip ring to the shaft and it should be infinity or several meg ohms.

If all checks out check the resistance using the brushs with at least one wire removed from a brush to as you do not read backwards through a voltage regualtor or field winding!

Also if you look closely at the brush holders sometimes you will see a + on one of the holders, usually, but not always the right hand brush is pos! If you still cannot determine the polarity you can sometimes use a DC voltmeter and try to read a DC voltage at the brush holders while the gen is running. Even a small DC millivolt reading is a hint as to the proper polarity for exciting the rotor! (the rotor will usually have some residual magnetism and you can read this small amount of DC voltage at the brush holders when running!

SAFETY NOTICE!!!!!

Be sure you re-install the long rotor bolt if you remove it to remove a fan by the brush holders. The long rotor bolt is what holds the rotor to the engine, therefore re-install the bolt, before do any testing and be sure that you use make-up washers the thickness of the removed fan so as the rotor bolt is secure when re-tighted without the fan blade!
