Spoke with Jeff - VR is bad. When the generator energizes the ATS swings the power over then the voltage drops and the ATS disengages. ATS sees good voltage again and transfers load to genset, voltage drops, ATS transfers to Inverters.... Vicious cycle I saw yesterday. Power Tech is unable to ship a VR today as they are doing inventory, call back Monday and they are almost $500/ea... Apparently the VR has been replaced previously as I have something that looks like an AVC63-6 but it's not (BE350). Also the white wire was on the 50Hz vs 60Hz... (that wouldn't effect the output/operation of the genset but could mess with the loads). So as I couldn't get the Basler AVC63-4 from Power Tech I found Advanced Service and Parts (ASAP) at partsfortechs.com. They had the correct Basler AVC63-4 in stock (55 of them) for $229/ea., a Taiwanese equivalent for $183 and the Chinese for $129. They say they sell so many of the cheaper Chinese models that they have a ton of the Basler in stock. Regardless I ordered 2, as this seems to be a common item with these generators. I bought the Basler's and figured they were 2 for 1 vs Power Tech - hopefully they arrive by noon tomorrow as scheduled.

I did ask Jeff about cleaning the air intake to the generator/alternator where the squirrel cage blows all the road dirt. He said do not put any water in there and certainly not any degreaser as it will remove all the grease from the bearings. So that answers the "are the bearings sealed" question - they are not. He said vacuum it out. I asked if I pulled the plate where the squirrel cage mounts was that the end plate that holds the bearing, he said he thought it was. I looked at the exploded diagrams in the manual and it looks like it's not. I'm probably going to give it a try taking off the end plate - there is so much road grime in there that it looked 95% blocked when I pulled the squirrel cage the 1st time. I like stuff clean. My biggest pet peeve and deterrent for wanting to work on something is dirty areas and systems.

We'll know by 12:30p tomorrow if I'm back in business.
