More replacing on bus

[Bob Lawrence]

Hi Curt,
The load should be 63hz with no load, dropping to 60hz with a load on it.
I use a Good Governor that I got at CW. I use it whenever the genset is running
to check voltage and Hertz.
Also keep one in the outside compartment and check any park's pedestal before I
plug in my SurgeProtector unit. It can't tell me hz's. Can't afford to lose any
electronics.
Forgot to add last post, when I put in the new air compressor, also added a new
alternator. The old one was only 130 amp. The new one is 160.
Time for a beer.
Wind here in Mathis is gusting to 40 mph. Can't put the dish up and watch "The
Unit", my favorite show...bummer.
