Booster switch has quit working

Hi All

The booster switch on My MH quit working this spring. When the switch is activated I can hear a clunk?? noise in a black box located in the left rear storage box by the inverter that is labelled " Battery Mode solenoid and relays". The fact I hear something happening when the switch is operated leads me to believe that the solenoid is working and the problem is somewhere else. I am guessing at this point a loose connection somewhere. But I don't know enough about the system and would appreciate it if anyone has any suggestion that would shorten my search for the problem
Thanks
Wayne Ridsdale

Those solenoids are usually the failure point. The contacts inside fail to make contact. Get access to the solenoid and put a voltmeter connected to the two large terminals. You'll see a voltage indicating the difference between your chassis battery and your house battery. Now have someone press the switch. If the solenoid is working, you'll see the meter read zero-- there is no difference because the two terminals are connected. If the meter reading doesn't change, the solenoid is bad.
Good luck.

just because they click does not mean they are working mine clicked but did not make contact. I replaced and now OK

Wayne,
We have the sister ship to yours only, it's the 36GD, '04 Horizon with C-7 330HP CAT. Yes, that battery boost solenoid is in that rear, shore power compartment, behind a removable panel. It sits right along side the house battery disconnect solenoid. Now, you don't say how long you've owned the coach and, how many miles are on it. But, while those solenoids are known to fail, it's not as often as some think. We got between 10 and 11 years out of ours.

We purchased ours 5 years ago and, it had 40K on the clock at that time. It now has 66K on it. I don't know if you know it or not but, that solenoid has a DUAL roll to play. Yes, #1 is the battery boost part which, links the house batteries to the chassis batteries so that you get all the power possible to crank your engine over.

The second roll it plays is, through different wiring, it closes and links your alternator to charge the house batteries. Now, here's the deal. That solenoid can be purchased in many places. And, based on how long it lasted before it failed, you can get one on Amazon for about $49.00 or so.

But, many on here have advocated purchasing either the same one or, one close to it, with SILVER CONTACTS. The factory ones use copper contacts. I personally don't think that copper's all that bad especially since mine lasted almost 11 years.

I removed mine, dissected it and, cleaned the copper contacts which, were not very bad at all. A little sandpaper and a dremel tool and, it was good as new. It lasted for almost 2 years and it started giving me trouble on a trip we were just on. Well, I figured what the heck, I'll just buy a new one. So, when we got home a week ago, I ordered up a new one, identical to that one, only with silver contacts.

That solenoid ran me $89.00 on ebay. I just installed it today. It's not a very hard job at all.

IN yours, yes, you can hear the solenoid closing. But, it's the contacts are not making good enough contact with each other to conduct the high current needed for either of it's operations. Not many would do what I did and disassemble it and clean them. I did it because I could. I like goofing with things like that.

Anyway, if you plan on doing the repair or, replacement, ask away, it's an easy job. I've done it several times without disconnecting any batteries. You just have to be careful and tape up the hot leads when removing them from each terminal. And, either take a picture or, write down where the wires go. There's not many of them. Good luck.
Scott
P.S. Here's some pics of both the new one and the old one. The old one, is on the left and, new on on the right.

And, if I can do this right, you'll see pics of it apart and what the contacts look like.

It looks like fun. I will tackle it this aft.
I bought the RV last fall. It now has 65,000 miles. So according to your experience the solenoid might be original.

You're quite welcome Sir. Here's a closeup of the new one. It really doesn't have any indication that it's got "Silver" contacts. It was sold as it did and, has a higher price than it's brother with Copper Contacts. So, I took a chance and purchased the more expensive one. The only thing I see in the picture that's different from the original one is "CS" on the name plate. Maybe that means "Contacts, Silver", who the heck knows?

114-1211-010 has copper contacts.
114-1211-020 has silver contacts.

In addition to switching to the solenoid with silver contacts, I added a couple of resistors to reduce the pull-in voltage slightly, as detailed (with pictures) in this (long) old thread: Yet another solenoid bites the dust!

The silver contact one was my second replacement between 2005 and 2008. It's been in place with the resistors since then and still working fine 8 years later.

I happened to stumble upon this tread Its just where I'm at at present .
Recently I purchases an 05 Winnebago Journey model 34H from an older fellow in his 80's
Its a very nicely equipped with a 350 Cat and full body paint with only 28K on the clock
Although it needed major cleaning
I can not avoid saying its been riddled with electrical issues
Here is where I'm at at present
The battery's where in need of charging , doing so I removed them which led to other problems ill get to later in another tread
I charged the battery and have reinstalled them keeping them on a couple Deltran battery tenders .
I can hear the Aux solenoid click Upon further investigation I found the switch in this condition as it did not release as it should I guess the PO never heard of Crazy Glue
With that said Im ready to attack the solenoid itself Does it come apart with just removing the screws ? Or will it take other tasks . In past years I have opened many of all kinds having boats in my past .

Journey Cat, I believe you need to drill out four rivets and unsolder the coil. You should see the same exact voltage on each side of the coil when activated. If both banks of batteries are fully charged you won't be able to really tell if it is bad. However, I have changed mine twice. Yes I rebuilt one and keep it for a spare. They can be very hot to the touch if left on a long time so be careful to not scorch your fingers.

As many of these as I have seen bad I believe they probably should be mounted with the large terminals up. With them down and the solenoid heating and cooling they can draw in tiny bits of moist air. There is no way for that moisture to escape when mounted this way. Mine was full of green stuff the first time I took it apart and it was only two years old.

Thank you for the response
I did see you post on another tread

" Tombones, if you are positive about which solenoid is supposed to control the circuit just put the voltmeter on the small leads and tell us what you see. Measure from ground to each of the small terminals. Do the same on the large ones. You could have easily blown a fuse while changing it and just have a new self inflicted wound. "

Could you explain further ? At present battery are out again . But while in I was seeing a similar voltage . Which has me confused as the switch that activates is momentary . That said hoe are contacts released when not in use .
As I did not check them while battery were in .
Lets not confuse the two switches & solonides . Because this one with the two fuses has a momentary switch also and Im curious as to how that circuit works also

Tim,
Thanks for the links to those switches. Those are outstanding and I saved them as pdf files and will share them in the future. I'm an ET and these switches can be quite complicated when trying to find a replacement. Those pictures are worth a thousand words.
