Shola Posted December 23, 2019 Share Posted December 23, 2019 The GE voltage regulator burns each time we run the engine. We have replaced 3 voltage regulators and they all got burnt. We also replaced generator. When we installed Bendix, we had high voltage. Anyone with idea of what could be causing this? Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted December 23, 2019 Share Posted December 23, 2019 First (which it sounds like you already have) make sure Gen and VR are from the same manufacture and compatible, been a long time but different manufactures have different excitation voltage requirements.

Yes, that was done. GE gen with GE VR while Bendix gen was with Bendix VR. Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted December 25, 2019 Share Posted December 25, 2019 Which engine generator are we discussing? Other generators on line before starting this one? Does it "burn" at low speed ground idle or at high speed ground idle? Quote Link to comment Share on other sites More sharing options...
Shola Posted December 26, 2019 Author Share Posted December 26, 2019 (edited) Thank you all, particularly NATOPS1, for your assistance. The problem has been rectified. We started by ensuring that there was no known short in the electrical lines. Thereafter, we replaced the voltage regulator, generator control panel and, most importantly, the #2 contractor. We carried out engine ground run and there was no more burning of the voltage regulator. Edited December 26, 2019 by Shola Quote Link to comment Share on other sites More sharing options...
