I have a quick question, does the HWH system run off of the starter batteries for the house batteries?

Jack,
Speaking of HWH slide system and engine batteries.  Early on in our Newell coach ownership I was having trouble with the HWH hydraulic pump pressure giving me all kinds of slide hydraulic issues.  The forum said, that low voltage (from the engine batteries) to the pump would be a likely culprit.  Hmm, at the same time I was having intermediate starting issues (like a bad connection starting issues).  Long story short I found a positive lead on my engine battery (the lead that goes forward from the engine compartment) severely corroded about an 1 1/2" up and under the heat shrink tubing.  Could not see it by looking at it but once I crimped a new lugs on all the engine batteries and have had no issues with the HWH hydraulics or starting issues since.
