I have a MEP-003a that stopped making power last week. Following the Tech manual and help from Triple Jim determined I had a faulty voltage regulator. Bench troubleshooting revealed faulty Q3, Q1 and Q2 had different signatures using a Huntron tracker, so replaced all three transistors. Re-installed the VR and had good voltage and worked with no issues for approx 2 hours. Lost power and troubleshooting revealed the VR again. Using a huntron again revealed Q3 faulty again. Re-installed the VR this afternoon and fired up the generator had 60hz 115v on the gauges for about 6-8 min then lost it. Shut it down for a few minutes and re-started it, gauges read good freq and voltage for approx 2 min then went back to zero. I hate intermittent issues!
Has anybody else seen a genset do this? What can cause Q3 to bad like that? Possibly something else on the VR?
Thanks in advance.
