Battery Question

I've found a phone cord attached to the positive terminal of a chassis battery.

Wait, the plot thickens: All three conductors are soldered to a tiny capacitor or resistor the side of a pin head. The assembly was imbedded inside a ring tongue connector filled with caulk, which in turn was stacked amidst the positive terminal's ring tongue connector.

What could this be?

Could it be a remote temperature sensor (not a resistor or capacitor) at the end of those wires? \ken

Some types of resistors can be used as a temperature sensor. Most battery temperature sensors are attached to the body of the battery though, not the terminal. Check and see if your Converter/charger has a temperature sensor function.

This is how my remote temperature sensor looks -- attaches right to the battery terminal. \ken

ok a quick question. Was the connectors soldered to the ring connector and the cap/resistor. Or were they attached to the cap/resistor on one end and it was attached to the ring terminal. Or was one or two of the wires attached to the cap/resistor and it attached to the ring terminal with any remaining wires attached to the ring terminal directly

What is on the other end just a phone connector or is it attached to something or is it just loose ?

Sounds like a battery temperature sensor for a battery charging device. Such a sensor allows the charger to optimally do its thing.

Yes, you have described a Thermal Sensor to a "T".. I have one on my Xantrex Prosine.. And,, it uses a 4 conductor phone type cord.

Same for my new Magnum MS-2812 . The old xantrex had the battery temp sensor attached to the side of the battery. You may also have a current sensor attached to the neg side of your coach batteries somewhere.

It is temperature sensor and it attaches to post as that is metal connection and best conductor of the heat.

Not famialer with your unit so search by model number to verify as some use this connection for load point voltage feedback.

It provides the battery voltage and temperature of the battery back to the charger so it can match battery.

Locate the manual for yours so you can verify how to correctly install the sensor then configure your charger.

The resistor is soldered to the three wires, then it was inserted into caulking crudely injected into the shank of the ring tongue connector.

When I pulled the assembly from the goo, the three solder points were of course touching. I can only assume they originally had some space between them.

Frankly, I haven't yet determined where the phone cable goes, or if it is even still attached to anything. Much on my plate: a relentless Code 32 generator fault, and a forward AC unit that I'm regasketing.

Thanks, Toni

I'll have to research that one. No manuals came with the coach.
