Voltage regulator issue
-
Ouch. Somebody has done some serious damage.
-
Dick, thank you for the offer but friday I leave for Sturgis. A week at Elk Ridge is needed at this point.
-
Great Jeff, a week at Elkridge will do you some good…..
Jon – I know, I was talking about the chassis regulator. We’re you in the whiskey?
-
Jeff, glad you all caught the problem, now the next test is if your coach has the ECC cabinet down in the first bay with all the computer cards in it I would make double sure all the functions of the SunMullon switches in the coach that operate all the lights, fans, heat exchangers, hot water heaters, aux air compressor and anything else they run work.
Operate every switch to make sure nothing has been damaged by over voltage.
All the current for the cards in the ECC cabinet get their power from the house batteries and all the lighted switches operate on 5 volts.
I do not know what the electrical limits on the high side would be for the switches but I would make sure and bring that to the attention of the dealer who installed the wrong regulator. Could possibly be some damage down the road.
You may try to contact Miles Circo in Florida about the limits of the ECC cabinets.
On your vintage coach I am not sure if CC was using that set up or not.
If you have all the little lighted square switches through out the coach ten you have it.

I do have the ecc system. The only two Gremlins I have are no power to wires 34 and 45. 34 looks to be a bad relay on the board in steering gear compartment. And 45 which looks to be the camera 12 volt feed I can’t find. Also if any one knows what #34 all powers that would be awesome. It looks like most of the 12volt dash accessories which I hope includes the power mirrors.
-
On a side note I wanted the ecc system. I’ve been fixing pinballs for 35 years and the parts for the ecc I already have on the shelf. A buddy of mine has a little bit older liberty. The indoor outdoor Thermometer was dead. $15 in parts and 30 min later it was all good.
-
The 34 wire is a 12 volt accessory feed for all kinds of things in the dash and other places.
Power for the dash radio, the cigar lighter socket and other stuff like the relay for the Zip Dee Autoawn if you have one.
There will be one in the ECC cabinet as well so check the fuse for it to make sure it is hot. I don’t think its a fuse on one of the cards but down along the bottom of the cabinet.
If I remember it operates with the ignition switch on, maybe.

Somewhere earlier in this post it was stated Vanners are not used on house systems. There are coaches with 24 volt inverters that use Vanners on the house side because of 12 volt lighting and other loads.
-
Mikee is correct, and to go even further some early model coaches had Vanner converters or inverters. (I cannot remember which because those coaches were in the 80’s I believe and I think I only ever saw one of them)
-
My 1991 XL has um for house systems.
-
Mikee, where was that I must have missed it. Vanners for the house were and may still be the standard choice. Sure Power was also used and the early versions had recalls for fire concerns. If you have Sure Power for house or chassis, check the serial number for the recall, they will replace it.
-
One possible problem understanding this thread may be related to the use of the word Vanner but not qualifying it to define the product.
Vanner EQUALIZERS are the most commonly used on our coaches and typically are used on the chassis to maintain the relationship between the 12 and 24 volt systems. They are unlikely to be used on 12 volt house systems, but are likely to be used on 24 volt house systems.
Older model coaches had other Vanner devices including inverters and or converters so just be sure what product the discussion should center around.
-
My unlikely coach has 2 Vanner Equalizers running house systems on 12 volt. 4 total in coach. No monitor. Of course it was built in late 1991 and who knows what, how, or why they did it. Cole Conversions out of Wyoming. Long gone.
Redo/edit ,,, as I found the monitor in cabinet above engine.
-
Way back when Prevost used a pair of 60 amp equalizers for the chassis because it was a 12 and 24 volt chassis. But I cannot imagine a 12 volt house system would need an equalizer.
Please explain or post a photo of the house Vanners

Jon,
I said if the inverters are 24 volt with 12 volt lighting etc then Vanners may be used to keep everything even.
