HI, my name is Doug,
I see you have done a lot of digging on this one !
Make sure you load test all battery fully charged and do them separately. One week battery will drain all down.
Not sure of the manufacturer of you truck to understand your wire schematic but I have seen the starter drain the battery's. Since the battery cables start at battery and go to starter then split off to cab and other things. I would remove cables off batterys, then take the cables off starter and then put cables back on batterys. Make sure you have starter cables taped off or covered so batterys don't blowup in your faced. Check for voltage draw and start installing small and large cables one at a time on starter to find were something is drawing voltage. From there you should be able to trace it down.
I hope this helps you out and please rate my service to you for tonight,
Some of the trucks have refrigerators in the sleeper. Some are 120 volts AC and some are 12 volts DC. The 12 volt style will run all the time unless they are turned off somewhere. The Volvo has a battery protection device that starts cutting out 12 volt products when the battery drops below 11.5 volts. May I ask what brand you have? Also how many batterys do you have stacked up at battery box so as I can have a better idea as to what amperage we are dealing with? Is the transmission stick or automatic?
I'm looking for a wiring schematic for that skid steer.
I'm sorry but I can't fine the correct wire schematic. I think there is a diode that has burned out and allowing current to flow backwards. Could be in wire harness or in a switch. I'm not familiar with this model. I will have to OPT OUT. I will contact my manager and have them contact a Tech with experience in a Caterpillar skid steer 257 B model.
OK, sorry I couldn't help you.
I sent a notice to the manager about this question being in the wrong category. I thought it was a class truck, semi truck, but it is not. The manager should contact you about this problem.
Once again sorry for the confusion.
