Gurus,

The Headhunter Mach 5 water pump is installed in quite a number of Newell coaches.  When it works, it is great.  My luck with the HH has been mixed.  I am on my third pump since I have owned the coach.   The most common failure points are the controller or the pressure switch.

I have another failure mode to add to the list.

My fairly new Mach 5 developed a leak IN THE PUMP CASE!  See attached pictures.  The leak was very small but it was enough to cause the pump to cycle.  Thanks to @"Richard" the leak was located see pictures.  It turns out that there was a fault when the case was molded and was just waiting to fail.  The leak is right under the inlet point in a crease in the case.

Note that the leak was not really visible from a cursory inspection.  So....if you have unexplained water in the floor of your water bay, you may have the problem.  To find it turn on a faucet enough to cause the pump to cycle and then use a flashlight to look for drips.  Of course the blue paper towel helps in finding leaks as well.

I talked to HH and they said this "is not a common failure".  I offered to send them pics, but they said they really didn't need those.  . If you have had a case leak in an HH pump, please post to this thread.  HH did say that the case is available for purchase.  (I used the case piece from my spare pump).

So I took our coach for fuel the other day (first time) and was cut off at $100.  Is this a credit card limit or gas station limit?  How do I get around this?

i bought a new water hose to go from the external water softener to the park hose bib.  

i like the flexzilla hoses and have alot of them for water and air.  

first glance says      "Lead in Hose"    i thought that was the old days.......nowadays you cant get within 25 feet of any lead without a hazmat suit.......

of course below it says drinking water safe......ha

my entertainment for the day

just a reminder and offer to anyone who wants to do the seals that require a cart to remove the slide with.  i have a really nice slide seal cart that i had made and is at least as good or better than the newell factory cart.  

you just have to come to my place and we can do it inside my shop.  no cost to you other than you have to help and buy seal and anything needed.  

with help from a few gurus and a neighbor we did my front salon seal and it is very doable.  

i live in arizona and would just need some advance notice.

Hello,
I am working two electrical issues that may or may not be tied together into one circuit.  What fuse supplies current to the black water dump air solenoids (both driver side and passenger side)?  Also, what fuse supplies current to the lower bay lights?  

Thanks
Steve Denton

Laureen and I have been hearing an air leak forward of the rear tires (single axle) on our 1984 Newell Classic and we are losing air rapidly from the supply (house) system. We can hear it from both sides of the coach, maybe a little louder on the passenger side. When we turn the coach off and the (only) compressor quits the supply air gauge on the dash quickly falls from 120 psi to zero. It takes only 15-20 seconds to lose 10 PSI for the first 60 pounds or so on the house side according to the dash gauge. The brake system psi holds fine and the air bags stay up. The coach's air system is simple, using air for brakes, air tanks, air bags, ride height adjustments, leveling and horn. We have front and rear six packs with MAC air valves. Nothing is automated. 

Today we spent some time looking around under the coach by taping a phone camera and a couple of Harbor Freight free lights to a long, narrow strip of wood flooring and taking videos of the underside of the coach. Doing so led to us finally finding our supply (house) air tank or at least one of them (don't know if we have more than one). It is right in front of the rear axle and about the middle of the coach. (The two brake air tanks are in front of the front axle.)

Please take a look at the attached  photo of the bottom of the supply air tank. It looks to me that a petcock or some kind of valve is missing off the square device in the center/bottom of the tank. I think this may be a major source of our air loss from the supply system. I did not actually crawl under the coach to check if air is coming out of that hole/area when the pressure is high but will do that probably Monday (tomorrow). Actually, I will figure out a way to check that without me crawling under there.

Does anyone know if a valve is supposed to be in that area? I would think so for draining water out of the tank from time to time. If so, what kind of valve should I put there? I would like to be able to drain it from the side of the coach by running a line over there.  Thanks for listening and for any advice.
