I had a problem with oil mist from the road draft tube sticking dust to the radiator. I had pretty good results using an engine cleaner concentrate called Gunk SC mixed with Diesel and sprayed on from the fan side, followed by washing with a water hose and sweeper nozzle. The Gunk/Diesel loosens the oily dust and carries detergent with it so the water will flush it all away. If you use this be sure to follow directions on the container and thoroughly rinse all the cleaner off as it will attack the paint on the radiator if left on too long.

My 2000 Endeavor intermittently did similar acrobatics. In my case, there was a break in the ground wire between the sending unit and the frame. The break was actually in the wire itself, about one half way along the length and it took multiple trips to the shop to find.

On my 2000 HR coach the dryer is located behind the drivers side rear wheel next to the hydraulic reservoir/pump for the jacks.

While you are checking things, take a look at the temperature at the outlet of the condenser coil. If it isn't getting rid of as much heat as it should the temperature and pressure will rise, overloading the compressor. If it is much higher than the other units then look for obstructed condenser air flow or possibly deterioration of the coil and fins. For verification, run water over the condenser and see if the amps come back where they should be.

From battle born "BMS Basic Features" "High voltage: > 14.7V If an individual cell voltage exceeds a prescribed threshold during charging, the BMS will prevent a charge current from continuing. ..... " I have been living with these things literally 8 inches under my butt for years now and I can't run if they go Chernobyl. Believe me, I have researched them extensively and carefully! I challenge you to break a Battle Born battery. They are, IMHO, seriously over priced, but as bullet proof as it gets.

I think you all are making this too complicated. LiFePO4 batteries have BMS (battery management system) built in. When the battery reaches full charge it will disconnect itself internally. Likewise, when the voltage drops below safe minimum it will disconnect to protect itself. I stopped using AGM's on my mobility scooter 4 years ago and installed USED LiFePO4's. (I have a spinal cord injury and can't walk at all, so scooter is in use 16+ hours daily) They are finally showing slight decrease in capacity (but are still better than NEW AGM's). With AGM'S I was replacing batteries two to three times a year and still putting up with sluggish operation. Only downside to lithiums is that they don't give any warning when going down. When you reach minimum safe voltage the battery disconnects and you STOP! I just got a new scooter and spent $840 for a new set of LiFePO4 batteries. I will never go back to lead!
