HWH Jack problems

[Richard Gideon]

Hi Don: I'd try speaking with a tech at HWH...nice folks. Last
summer on our trip home from Glacier NP & Ernie's Park County
Fairgrounds, HWH installed a new fitting in my RR leveling jack and
covered it under warrenty! I even explained that the leak was due to
operator error (me). The job took about 45 minutes and when I went
to pay for the fitting and labor, the office manager said, no, your
banace is 'zero' you are good to go! Good people and they know how
to deal with customers.

It also osciallates somewhat in speed. It is drawing 60-70 amps at
that point.

uncommonly, but not always, it will do that after it has stopped and
restarted, either manually, or because the low jack has completed and
it is running the remainder down. Sometimes the speed never
increases, and in those cases the run-time will usually expire before
the jacks are all extended, and another run will be required.

Repeated clicking of a manual lever would eventually result in the
motor starting. It did this for three consecutive uses, then for the
last two including when we arrived home it did operate on first
switching. When the relays kicked and the motor failed to start,
power draw was under 20 amps, around what would be expected for
solenoids and valves - the motor was not apparently drawing any
current.
