I checked the instruction manual for the hays controller and it does have a pendulum for sensing motion. That is probably why you reading are not that high and only changing a small amount.

Maybe Darrly with post the operation manual for your controller.As I am not good with computers.

Just trying to give basic ideas as how to test things. I have a prodigy that controls out triple axle Teton. If the brakes are applied by hand there is more brakeing effect than with the pedal.

Without knowing what magnets you have and no experience with your controller I am just giving a general thoughts on how your brakes should work.

Safe Travels , Vern

Just my thoughts on electric drum brakes.

There should not be 12vdc at the magnet when hooked to a controller. Full voltage is for when the towed vehicle is disconnected from tow vehicle and that is when the brakes get maximum stopping power. As in locking drums tight.

If you jack up a wheel off the ground and it will not rotate, it probably getting the voltage it is suppose to be getting. Not full 12vdc voltage.

You did state then the brakes did give resistance when moving and applying with controller

Also if there is anyway for the controller to sense motion it probably will not pass needed voltage to test the brakes for proper amperage while sitting still.

Use full Dc power from the charge line on the cable through a fuse and connect it to the brake wire. That should give correct amps for the brake system for testing.

Or just pull the emergency electric brake actuator and test for amperage. As soon as you pull it put it back in just to make sure it will go in. Then test with amp meter for proper operating amps.

If you pull the emergency brake actuator and it starts smoking you have a direct short in the system. Yep had that happen at work a time or two. That is why you want to practice putting it back in as soon as you pull it out the first time.

Make sure you put emergency connector back in when you are done or you may slide the tires when you leave.

Hopefully this will save you some more labor. Just look at it like doing yoga.

Also check your voltage and amperage with a good meter when the compressor is under load. Early in the am to see what the unit is doing before everyone else has there units running also. Also watch the incoming voltage is at the post

Are you on 30 or 50 amp service.

Make sure your water heater is not on electric at the same time. The fan motor may need a little lube at the bearings .

Then when everyone else is using there a/c unit what is the voltage. If it gets towards 110 volts or lower then the amps will be going up.

It probably is your incoming voltage is the problem. Also you could have a wiring connection problem in your RV.

I think if it is the compressor it would trip the breaker sooner.

It could be two thing together that is your problem.

I just looked at your post again. If it was tripping your breaker in twenty minutes or less it may be the compressor.

Safe travels, Vern

We are at the North Ranch till about April 1st. With a side trip to Quartzsite tomorrow in just the truck.

We moved our winter location from Brooksville Fl to the Red Barn RV park, acrossefrom Blueberry hill

in Bushnell Fl. Will be hear until april first then off to the southwest to look around.

If you are in the area stop by for a visit.

Safe Travels, Vern

We left Bushnell Fl. on april 27th. Stoped at Gulf Shores Al, New Braunfels Tx, Santa Fe NM, Vernal Ut, and Ennis Mt. We are now at our summer spot in Kalispell Montana. We stay at Rocky Mountain [HI] campground on lot 51, two miles north of the square in Kalispell.

If anyone is in the area stop by or call[ comerial menber # 469] if you are in the area.

I work from Polson north into Glacier national park doing Rv repair. Last year I did see several HDT'rs and stoped to talk to them. There was some that we seen on the road but had no idea who they were.

Safe Travels for the summer, Vern

We pulled into Talladega Nights RV park for a week. Accross the street from the Talladega speedway in Allabama.

Then we are going to vacation our way through Texas to Utah and then to Kalispell Mt for the summer.

We may stop to see Pam and Smokey in Missoula Mt on our way north in may.

Vern and Chris

We are at Rocky Mountain HI campground in Kalispell MT until sbout 8th of sept. There is alot to see and do in Montana. They did open the Going to the Sun road a few days ago.

Safe Travels to all, Vern and Chris

We finally left Fl. for the summer. I finished installing a new awning on tuesday morning at eleven am. Then rearanged some s--- in the jeep and loaded it on the truck. Then put the service trailer on the rear bumper forks, then hooked up the fifthwheel. After leaving thursday evening we arrived at Talladega on friday morning. It is to late for working here so we are going to enjoy the race weekend.

Then tuesday we will arrive at Richmond speedway for the next race. Safe Travels Vern and Chris

We left Pa. last sunday afternoon, stoped for a short visit in Hilton Head Sc. Then spent two days at Sumter Oaks in Bushnell Fl. Now we are about fifteen miles south west of sumter Oaks at Cloverleaf Forest RV resort for the winter. If anyone is at Sumter Oaks pm us and maybe we could come over for a visit. Vern and Chris

We are north of Palmetto Fl. till the end of march. This is our first time to spend the winter in the south. It feels odd not thinking of leaving in a week or two. We are about twenty or so mile's south of where the Tampa RV show location is. Vern
