PW Excel battery tray

I fixed the battery box problem, the slide rails were corroded. I don't think it was ever checked as the water was down to the plates. I cleaned and oiled the rails and all is well and hopefully it will be fully charged by tomorrow. This unit was a left over 2012 model that was purchased new less than 6 months ago and the owner sold it due to a death in the family. It has not been maintained the way it should have been, the hot water tank was never used, it's still in the winter valve position, nothing that runs on propane was used, the air bags had no pressure in them, and it needed a good cleaning which I took care of and it now looks like a new unit, I'll polish and wax it in a couple weeks. Chuck, if you read this, can you tell me where the compressor is located, I ran out of time over at my building today and didn't look through all of the compartments. As I mentioned, the manual is from an earlier year and doesn't show a location for the compressor.

Thanks,
Nick
