Are you running an AGM battery and power hungry accessories like a fridge?
I don't have any issues per se other than I suspect my Optima is not getting a proper charge, reinforced by my fridge behavior.

I am running AGM but no fridge.

RockAuto. The harness side connector appears to be Standard Motor Products #S2084. The sensor side connector doesn't appear to be available separately, but a cheap sensor is about $15 at RockAuto, and you could cut it off one of those and use the pigtail.anyone happen to know where I can source male and female connectors for the battery temp sensor?
Battery at rest is 12.58.
Resistor is 14.14 k at 77 degrees.
Voltage running is 14.03v.
My original white 97 tub...I didn't move over the sensor...is 12.5 k. (No battery sitting on top of it )

Care to share what brand you went with?
I'm strongly considering dumping my Odyssey.
You do a group 34 or stuff a 65 in there?

Just considering dumping it.
Pretty convinced the TJ PCM voltage regulator isn't set up to charge a modern deep cycle AGM battery.
After a day of driving the battery voltage was 12.3 - 12.4 volts according to our cheap Amazon F40C4TMP fridge. As soon as the compressor would cycle up the battery voltage (according to the fridge) would drop to 11.7 v and the battery protection mode would kick in and shut off the fridge.
Fridge allegedly draws 4 amps in full tilt bingo mode and 1 kilowatt per day.
So ...I either have a battery problem, a charging problem or a fridge problem or all of the above.
I could get a dual battery tray and double down on Odyssey...maybe a red top for the primary battery with a DC to DC converter/charger to the existing Yellow. Move my USB and power ports to the Yellow. Also considering a small lead acid race battery for the primary.
Thinking the PCM voltage regulator might be programmable... but really lothe to mess with the PCM.
I could ditch the Amazon fridge but spending a grand on an ARB would really hurt the wallet. That and the Amazon fridge size is pretty perfect and even the small ARB is bigger.
Also thinking of something like a Jackery battery box to run the fridge. Would be nice because we could augment power with solar for non driving days.
