Generators / st 10 kw gen head
« on: July 22, 2011, 03:40:09 AM »
I have a st 10 kw gen head running at 1800 rpm 4 pole 120/240. I have it jumped in the dog house for 240 per the instructions.
so I have 120 x2 with a newtrel .
problem - when putting a load on more than 10 amps the voltage drops down 120 down to 109 the frequency stays at 61Hz thou .
I have checked all connections and checked the contact of the brushes with the slip rings - with a meter less than 1 ohm no open windings either and the windings read the same on the meter
rectifier tests OK
Any ideas i can try to find out whats up?
