12V Interior Lights

[htbradley]

I have the Intellitec Multiplex Switching System in my coach that
controls all the lights via 8 pannels.

The other night all the lights came on and those that are dimmable
started cycling through their dimming cycles also all the "Amber and
Green" lighting in the panels were on and I had no control over any
of the lights or water pump. Interesting expirence at 2AM.

I got all the lights lighs off by using the "House Battery-disconnect
switch. The next day I found that if I disconnected "J2 Power
connector" of the EMS Control Module for 30 seconds the problem was
sort of fixed for a short time then came back. By repeating the
above and removeing all power from the coach for 5 hours it seems to
have fixed everything. No occurances in the past 7 days.

I have calls and emails to CC and Intellitec, but no response from
either. Didn't expect any response from CC.

I have an Allure 470 Coach #31461, 42ft Siskiyou Summit, quad slide.

Thanks,
Terry

Could have been moisture on a circuit board or a bug...

Be sure to check for loose grounds. I would probably just add another ground to the circuit; to be sure.

Got an Email from Intellitec yesterday saying the following: "Sounds like a problem with poor grounding or dirty supply voltage. You can check all the grounds to the output modules but you'll need an oscilloscope to check for a dirty 12 volt supply."

Yesterday checked all the grounds all good today will checkout the 12V supply. Since all is working ok now don't expect to find anything.

Dirty DC probably won't come and go. Intermitant problems are the hardest to troubleshoot because until the problem is happening at the moment you are ready to check the circuit, every thing will check good.

go into the bay by the converter, you will see 3 or 4 black in line fuse holders screwed to the wall. They say 7.5 check those because if one blows, you will lose power to the whole coach. Also, if the light problems consited in one area of the coach, or througout the coach, then you can track it down. Inside you closet is a box with the intellitec boards in it. I believe an allure has three boards, each controlling a part of a coach. Theres the bedroom board, bath room/galley area/ and the front galley area to the dash area. Intellitec is tricky because when I worked at CC we had bad control pads that would do that, and need to to be replaced, and also had bad main boards that would do that. So I would just start with the grounds, and then see if it happens again, where does it do it. The Back of the coach only, or the whole front. But it sounds to be like a bad pad. I worked at CC for over 5 years and expierenced that alot. Work at a great shop in Albany, Oregon now, if interested I can send you info on what we do.

Checked the 12v with my 40+year old O-Scope, fixed jets in Viet Nam, 12v looks good. Also, checked all the grounds inside you closet where the intellitec boards are at. The problem is thought all the coach ( bedroom/bathroom/galley area/ and the front galley area to the dash area.

sounds to me like the Pad. If one of the Pads go out, the whole system acts up. Intellitec systems are very touchy. Its like over doing the plumbing, next time instead of house power switch, try to overide swithes on the side of the box in the closet. I will investigate more for you.

clb250ford,

Is there anyway to isolate/troubleshoot the pads?? I live in So. MD so a trip to Albany, OR is out although we love it out there and are moving to the Columbia Gorge area in April.

CC and Intellitec have been NO help.

[clb250ford]

Troubleshooting the pads unless you have some sort of troubleshooting software I don't think so. I remember when they went out, we would just get another one off the shelf. Its no suprise CC is no help. They owe money all over town and refuse to answer there phone. I Was management there, I know how they work. The best bet is maybe just buy a back up pad. In your coach you have serveal, so that might be hard. When you move to the Gorge, and need anything, let me know.
