The unit quit putting power out motor runs I am getting 4-5 volts out of the receptacles I took the cover off the end unplugged the connector from the windings to the control panel and got 1.5 - 2.5 volts out of each lead (4 total) I checked for continuity between the leads and have it between black and brown and blue and white I tried to excite the magnets with a 12 volt dc battery plugged into one of the sockets without the generator running of course and this did not help.. I don't know how strong the battery was though. I inspected the voltage regulator board (I assume) and did not see any corrosion or burn marks on either side. This unit apparently is a synchronous brushless type so obviously no brushes to inspect. Now what. It is a $2,500 generator with 420 hours on it only. It has been maintained and just quit putting power out while it was running suddenly. It gets used approximately once a month for 15 - 20 hours.

Hi,
I need more detailed info. Look for a tagwith lots of numbers/letters. I think Ingersoll may have sold the division.
Peace,
