MicroPulse System not Working

[robinndi]

Con'td from post #17 above describing Catcon issues.

My 27FB is now back with the dealer, and hopefully warranty should cover it. My warranty issues:

1. Two dead Catcon sensors
2. Dead waterpump
3. Leaking toilet flush switch
4. Grossly misaligned axle (worn-out tire in ~4000 miles)

I already paid for a new rear window glass that spontaneous disintegrated enroute.

Add also a door catch that needs different adjustment( washers) for summer and winter.

Airstream seems to charge top dollar, but the corresponding quality does not seem to be there. Six issues in 18 months, none of which seem to be fair wear and tear.

Got a reply back with some drawings of the holding tanks. On my Classic the black is the first tank looking at the dump value, then the gray. Two handles, left handle is the black then the drain and the right handle is the gray. The sensor locations are outboard of the exit drains on the tanks.

If I have to replace a sensor what tool would I use the cut a clean hole. The holding tank is separated from the pan with 1/2" insulation. This is the reply from AS

Hello, I put the prints for the tanks in the attachment for you. In our service center we cut inspection holes in the pans to work on the sensors. There is an 1/2" of insulation between the tank and the pan so do not cut to deep. Then we make a cover to close off the hole.


I've attached the prints of the gray, black and the drain plumbing.

I haven't had to make the cut yet, but expect to in the future, if not for the sensors at least to get to the dump valves. Hopefully someone who has done this will chime in. I believe one of these multifunction tools as they are sometimes called might be the ticket. I have one and have used the half circle blade to cut sheet metal. It doesn't rotate, but vibrates and works a lot like the saw the orthopedic doc use to cut casts off. Go slow to control the depth. I snagged this pic from the Harbor Freight site, but have seen them at Sears, Walmart, etc. there are a variety of blades for various tasks.

Are the sensors mounted on the drain pipe between the tank and the dump valve?

The dremel works great! Easy to control so you won't go too deep.

The sensors unscrew from the tank or pipe adapter. Check the link.

CAUTION! Do NOT over tighten the replacement sensor or you will BREAK the adapter!

You can choose whatever diameter hole you want with this tool bit for your drill. I wipe the area with transmission fluid as the lubricant during cutting:

The bottom of the waste holding tanks are closer to the ground than the water tank. In order to use that tool I'm imagine you'd have to run that side of the trailer up on some ramps to get the required clearance to use that tool with your drill.

Would this item be enough to lift the AS up to do this work? It supposed to lift it 8".

Kelvin - you are correct. I used a similar lift on my trailer. While you have it up, check the lubrication on the stabilizer screws. Easy to inspect and clean debris if any.

Yeah but need a set for each axle so you don't overload Liftimg axles and tires

My new to me 30 Classic Micro Pulse System was not working. So, I opened the fresh water pan & found the sensor. The wiring was removed by the po. Then opened the rear pan & found the wiring was removed by the po. Okay, so now all are rewired. Still not working. Called Canton & left 2 messages last 2 days. No return call. E-mailed Canton twice
...no response. Customer service is worse than their crap system.

Search the Geo Method on this forum. After switching to this method my black tank sensor now works perfectly.

Hi Harry,

I have a 2004 Classic 28. The older Micropulse sensors are usually fouled and don't give an accurate readings even when working. I would highly recommend that you replace the system with a SeeLevel 709 tank monitoring system (that's what I did). The sensors for the system are mounted on the outside of the tank, so they do not foul. You can use the wires from Micropulse to hook up the 709 in the same location as the Micropulse panel. If you are interested, let me know and I can give you more info on how I did the install. You can also Google SeeLevel 709 and get lots of information.

I put the system in this summer and I am really happy with it for dry camping.

Good luck!

Dave - how did you gain access to the tanks to mount the sensors?

[GMFL]

I swapped mine to a SeeLevel system this year when I changed out my freshwater tank. I was able. To use the existing wiring from the micro pulse system. Here are a few pics

[harryk]

Nice looking install ! I will have all new sensors and Catcon says my motherboard is ok...we will see. Any more problems and its all gonna go in the trash.

Hi DMT,

The previous owner had cut an access port under the area for the black and gray tank valves. I was able to get through that area (for the black and gray tank sensors).

The fresh water tank on the curb-side had a small access port cut under the drain plug. I enlarged that hole and my DW also reached down through the closet floor to position and install the sensor strip.

The holes are now covered with sheet-metal held in place by screws. I could take some pictures if that would help.
