I know I haven't been active. I have some doozies to share around the camp fire though. We're all well, and I'm looking forward to catching up on everyone.
That doesn't look like it's working.Bluetooth stuff for the fridge and battery. Truck is currently off.
The DC/DC charger is supposed to sense run voltage to enable charging. If not it does have a port for “smart alternators”, whatever those are. The fridge carries low voltage shutdown as well. There is a circuit breaker in the battery box and a relay to control the fuse panel.
I turned the fridge on right before this series of posts so it’s been outside in the sun all day.

Single, it wasn't charging because the truck was off.That doesn't look like it's working.
Do you have a dual battery system
I'm losing my mind trying to get my Cruise to work, so I haven't had the truck running for very long at a time.
You're talking about a thermoelectric cooler (aka Peltier devices). They are very inefficient, as they constantly draw a lot of power and create a lot of heat to transfer the heat. This makes them much better warmers than coolers. I would never recommend for someone to leave one of those plugged in for a long time (especially overnight) if they also need that battery for starting. Also, a lot of those units don't even have thermostats - they just run constantly (sometimes with a noisy fan). You just get some fixed temp difference (over time) like 30F, so if it's 80F outside, the cooler is at 50F (on the cold side, warmer on the opposite) and if it's 50F outside, everything freezes.My dad had a 12v cooler in the truck (semi) in the 80s that would get pretty dang cold.
You could flip a switch and it'd get warm instead if you'd rather have that. Really cool setup.
We used similar technology in cooling computer panels in the field at my last job.
Essentially some unit that gets hot on one side and cold on the other with power. And reversing the polarity reverses the effect.
All they do it put aluminum fins on both sides.
To make cold, you generate heat. No getting around it.They do throw a lot of heat on the outside though.
Absolutely, but these small thermoelectric coolers are drawing like 4-8A @12V all of the time. It's not in the same category as a compressor-based system.To make cold, you generate heat. No getting around it.
I also had to use a relay to provide the ground or +12v signal to the violet wire. Previously my turn signals were cancelling cruise. Must be some crud down the wiring at the taillights.Cruise is fixed. It had my pulse per mile for the speed sensor set to my actual number instead of what the sensor is designed for. Not sure where I went wrong there. Following that, too much slack in the cruise cable. Good support from Dakota Digital.
I got posted on the DBBB reel from last year if it works:
