Hello,

The overvoltage is usually caused by a defective voltage regulator. It sounds like you have an intermittent bad connection within the sensing circuit. I can get your board tested or rebuilt, or you can replace it with a less expensive after-market regulator. You can e-mail me: parts@partsfortechs.com or call my tech help line at 717-274-9396.

Regards, Dennis

hi texan
there is several places you can find parts but the reason i am writing you is i have the very same problem you have with your gen but some wires are cut and i am ask you as a favor some pictures of your gen on the starter side of the unit i need to know where the wires go on this side as some someone decided to cut them off. a pic is worth a thousand words. you can get rebuilt voltage reg from www.
flightsystems.com you can email me at popscat@aol.com if you like
