rlbarkleyii Report post Posted August 30, 2013 Last month had to replace pump motor and two relays, this month the rear extend relay is out. I need to find some sources for parts, documentation, and /or comments from anyone else who has gone thru the HWH madness.

cinhrvs Report post Posted November 28, 2013 If you call HWH Corp they will give you the name of the nearest authorized dealer/installer. They should be able to help with problems and parts. I had mine installed in Elkhart, Ind. and when I had a piston issue they where great. Share this post Link to post Share on other sites
rlbarkleyii Report post Posted October 13, 2014 Thanks All. After several additional incidents with the HWH hydraulic system, found that my negative terminal was not torqued properly. Cleaned and re-torqued to specifications all battery terminals and seemed to have cured the problem. BTW applied dielectric grease to all terminals prior to tightening. Thanks everyone for your help.
