The Generator gremlins took a break for awhile but reared their ugly heads again.  While at the Darlington Nascar race and dry camping we lost 120v power.  Generator was running fine and continued to run after power was lost..  Trouble shooting showed 120v on one line at the transfer switch and zero volt on the other line.  Checking the voltage at the generator main circuit breaker showed 120v on both circuits at both sides of the breaker.  Located and opened electrical junction box where 6-3 wires from coach are connected to 6-3 wires from generator..  No power measured on one line at junction box.  Trouble is definitely between the junction box and the generator circuit breaker.  Found the wire broken under the shrink wrap at the connector at the circuit breaker.  AND READING BACK,  I'M NOT THE FIRST ONE TO HAVE THIS PROBLEM.  Anyway, fixed it and that's another cheap fix.  Just don't value all that trouble shooting time.

I have a 98 270 with a PTS IDL 8000 Ft Power Tech gen powered by a 3LB1PV Isuzu 4-cycle in line 3 cylinder. On a 3500 mile trip to the UP I was running my two A/C  and would get a studder on the Isuzu that would drop the cycles and voltage just into low range ( 108 volts).
I've never had the arrestor plug out of the muffler (and having difficulty getting the brass plug out. Could it be as simple as carbon build up in the muffler? I recently lube oil / filtered the Isuzu.
I am concerned the voltage drop will damage the a/c etc.

Paul,  We have the same gen, but unaware of what or where is a Spark Arrestor and what does it do? We do have a Progressive Industries EMS wired after the transfer switch that can protect our roof a/c when gen lowers voltage.
On a separate issue we did have our gen put out 160 AC volts for a moment, then back to normal, than later repeat the high voltage, which caused EMS to open, but still display the high voltage.  Power Tech told us it is a symptom of a failing voltage regulator, which we replaced and the high voltage issue is gone.
