LPG master problem - Steve & Kathy Enfinger - 11-22-2005 14:45
None of y'all came looked at our "bird-for-sale" so we're planning a
trip to Arkansas for Thanksgiving to visit Kathy's family. May as
well travel in "comfort".
Two times I've found you have to work on these "beast" ... when you
use'm ... & when they don't get used. My coach batteries were
discharged in a very short time last time out ... I found the "coach
load - leg two" gauge reading 20 amps (generator panel) while
plugged up to shore power with nothing running. Isolated it to the
LPG master switch. Amperage draw stops when turning off the LPG
Master switch on the monitor panel (above sink) or when pushing the
red switch on the LPG "detector" panel located at floor level beside
fridge.
Does this indicate a problem with solenoid valve in LP line? Is
something really pulling 20 amp load (must be hot) or is the reading
eronious? How can a 12 volt dc circuit effect readings in the 120
volt ac "leg two" amp meter? Guess you can tell I ain't savey on
this part of the coach.
I appreciate your assistance as we leave Wednesday afternoon ...
don't wanna travel with anything "unsafe".

LPG master problem - Ralph L. Fullenwider - 11-24-2005 02:11
Hi Steve:
A couple of questions on this one:
1. Do you see this 20 amp draw when running the gen set?
2. Leg 2 on the gen set panel? not clear on that one. As the amp draw on
that panel is DC draw.
3. Is the dc draw ( with the LP master switch on) still there when not on
shore power?
The leg 2 AC meter is activated from the house type circuit breaker in the
main AC power distribution panel.
If you have or have access to, an clamp on amp meter, set it to dc amps and
clamp around one wire coming from the lp master switch, then on the other
wire, this will tell you; 1. which side the problem is on and 2. the actual
DC amp draw when the switch is on. I can't think of how the DC circuit is
enacting on the AC amp meter on the AC power input and amp draw, unless it
is EMF (wires wrapped around or close to, the AC wiring,) going to the
meter on the panel.
You can get a high amperage draw from a high resistance short. A very
common place for this high resistance draw are the DC cables going to the
aux bat tie switch which also goes to the hydraulics HWH pump.
Safe travels,
