birdshill123 Posted June 23, 2021 Share Posted June 23, 2021 (edited) Being stuck in Canada I had our 08 Dynasty in enclosed storage. I removed all the batteries and they have been stored connected to a battery maintainer I was cleaning up the battery trays and noticed a broken wire in one of the house battery trays. It is a flat grey telephone style cable with 4 very thin wires. Red,black,yellow and I think green. The wiring was disconnected from the terminal. 3 of the 4 wires were poorly soldered together. The red was not. Strange terminal. Thick copper ring and a bell shaped end where the wires enter. The bell is quite large and was filled with some sort of white sealant. Nothing was crimped. End of terminal had a boot that tapered to the telephone style cable. I am now wondering whether it was hooked to hot or ground. What is that cable? I am wondering if it is something to do with the inverter. Any suggestions? Thanks Edited June 23, 2021 by birdshill123 Link to comment Share on other sites More sharing options...
Ivan K Posted June 23, 2021 Share Posted June 23, 2021 I would guess a temp sensor for the charger eventhoug mine does not look like what you describe but some types mount to a battery stud. 1 Link to comment Share on other sites More sharing options...
vito.a Posted June 23, 2021 Share Posted June 23, 2021 Yes. It's the temp sensor for the inverter. Not super critical. If you unplug it from the inverter it will run fine. Link to comment Share on other sites More sharing options...
birdshill123 Posted June 23, 2021 Author Share Posted June 23, 2021 Thanks but my temp sensor is sandwiched between 2 of the batteries I have the wiring diagrams but nothing in there for the house batteries. I do not understand why all the wires were soldered together. Why not just run one wire. Could it be for the alladin or the dash medallion? Strange.

birdshill123 Posted June 23, 2021 Author Share Posted June 23, 2021 Vito. I am not doubting you but I already have a temp. sensor. Why would there be that many wires? Link to comment Share on other sites More sharing options...
Ivan K Posted June 23, 2021 Share Posted June 23, 2021 Do you have a solar charger? Those also use a sensor to adjust. Link to comment Share on other sites More sharing options...
birdshill123 Posted June 23, 2021 Author Share Posted June 23, 2021 Bingo! It appears there are 2 sensors. The Magnum attaches to a battery terminal. I still do noy know if it is the positive or negative The sensor attached to the battery case is for the Monaco installed solar panels. I will have to call Magnum for info on how to repair the attaching of the lug to those wires. I think the white compound is some sort of heat proof compound. Thak you for the help.

waterskier_1 Posted June 23, 2021 Share Posted June 23, 2021 The battery polarity is not important - it makes no electrical connection to the battery. It is just using the post as a mechanical way to attach to the battery. Some sandwich then between batteries, some glue them to batteries. The bell shape is the thermocouple, and the "white sealant" is likely thermal paste to help conduct heat. Link to comment Share on other sites More sharing options...
birdshill123 Posted June 23, 2021 Author Share Posted June 23, 2021 Thanks. Mine is the original sensor. The new ones are quite different. The same shape as a breakaway switch. Replacing it would be a big hassle. The inverter is in the second from the front bay. Attached to the ceiling. I would have to drop the ceiling in the next bay The wire probably exits before the wheel well. It is my understanding that you can just disconnect the sensor. The inverter then defaults to one temp. setting Link to comment Share on other sites More sharing options...
