Generator control board, LXi

[David Brady]

Folks,

I notice that my generator comes on way too
soon and stays on way too long. I poked around
a bit a found that the radio shack power supply
powering the generator control board was bad,
so I replaced it. In the process I found that the
basement receptacle that the power supply was
plugged into is not powered by any of my inverters.
It's only powered by shore power. This seems odd.
Why would the generator control board only want
power when I'm connected to the shore. It seems
to me that regardless of shore power, the generator
control board should be powered all the time. The
control board is in the basement compartment on
the drivers side of the coach and directly behind
the front wheel. Is my receptacle wired screwy?

TIA,
David Brady

Hi David,

The autostart generator in my LXi works on either "Low AC / Low
Battery" or on "No AC". I was under the impression that the outlet
served as a AC voltage sense point too. Therefore, if it was on the
inverter, it would not sense that the shore power was out. I'll
have to get into the circuit to actually see whats up. It is one of
those things that has always worked and I've never had to check.
Yours, being newer, may be different but if mine starts on "no AC",
it will run until AC is restored. If starting because of low
batteries, it will run 2 hours and check again. 2 more will be added
if batteries are still low. I've never had a situation where it
started because of "Low AC Voltage" and only believe it does because
of conversations with the factory. One other note; the Radio Shack
power supply on mine is an adjustable output voltage model. Was
yours? Did it somehow get set to the wrong voltage for the board?

Thanks Rich,

Your email makes complete sense. I also found
more info at http://www.westhaverassociates.com/gencon/FAQ.asp
It seems that the only use for the radio shack AC adapter
is to monitor shore power, hence, when shore power
disappears, the voltage from the adapter goes to zero.
I also spoke to Larry Westhaver and learned that BB
installed an incorrect AC adapter. He said that the
universal, multi-voltage adapter, is not suited for his
gen ctrl board. The universal adapter provides regulated
power which does not allow the ctrl bd to detect
brown-out conditions. On his web site he specifies
radio shack part numbers for fixed voltage adapters
which do not provide so much voltage regulation.

Thanks for your help,
David Brady
