Recently, I posted a message on the forum offering to share some info regarding HWH leveling systems.  Several members have requested a copy so I was going to send the info to them by email.  I am not sure how to do that since the complete email address is not shown.  Does the entire email address automatically get completed when you click send?  As you can tell, I am not very computer savvy, but I wanted to share this stuff since it wasn't easy to gather and folks may find a need for it later. 
 
The first item is an HWH wiring diagram, attached to this email, for the 600 series leveling system Master Relay (HWH replacement part number RAP7505) and the Pump Relay (HWH replacement part number RAP0533).
 
The second item is a link, http://www.hwhcorp.com/ml2201.pdf, to the Operator's Manual for the HWH Series 600 Hydraulic Leveling System which is on my 97 BBWL 43'.  This info may be useful to include in the Files section of the Forum but someone else should make that call.  The manual for BB of that year, or those years, doesn't exist but in tracking down additional info, one of the HWH technical guys said our system, at least mine, is really the same system used in the Holiday Ramblers and that manual was available via the above link.
