Carrier Ultra Xl Manual Ndm
Hello all, new here and im having some issues that i thought someone on here might be able to help me out. 1st Amp gauge inside door is reading +40 all the time, i have changed alt. And battery and still no change. 2nd im having an issue with it freezing up solid when i get a hot load on that needs to cool down(example), put a load of corn on that was fresh picked and iced down but was still pulping 55-60., set unit to 40. unit froze up, set to 80. since manual def would not kick in, defrosted, set back at 40.

1 hour later froze up again, has been flashing 'CD Sensor' on screen, just need to know what this means and where it is located, or even a part number. Thanks Site is great DD. Yeah i know a little about reefers on what to mess with and what not to for sure, and as far as the unit being a temperatue maintainer i know that to, but it should have defrosted on its own especially set at 1.5 for defrost, i was just thinking the cd sensor was doing it. If the amp gauge is bad then why is it drawing everything out of the battery when it is off, once its off for 1 hour it doesnt have enough juice to start it, i have to jump off truck or leave cables on to keep it running.
Im at a loss on this one. What does the micro show for voltage when it is running. If it is lower than normal (about 13.4) you may have a loose connection at the ammeter as stated before or another good place is the maxi fuse (80A) fuse holder. Haynes repair manual hyundai accent. Also, did you put an OEM alternator on it or a local rebuild. It seems local rebuilders have a hard time rebuilding Carrier alternators. I take a lot of fresh rebuilds off that are bad. Try taking the pos.
Wire off of the alternator (with the unit off of course) If it sparks when you connect it, that is probably your problem. Just to be clear here, is the battery dischraging when unit is off or on?
Do you have a DC ameter? I'm interested to see were this goes.
Don't give up on us yet! To drain battery or request 40 amps, its a short to ground somewere. Keep posting:) Yes it is discharging when off, ill try pulling relays in am when i get unloaded and get home, Alt. Was replaced with a factory carrier unit, display says it is working fine shows between 13.4-13.8 at any given time. I got my wiring diagram to tell me where everything goes and what it is so ill guess ill try that.
