anyway to bypass low voltage sensor?

anyone know where the low voltage sensor is located?? or how to bypass it?? mine must have just went out on me. I can pull into parking space, shut truck off, and plug in 100 watt inverter for computer and the low voltage alarm will go off within 30 seconds. so i unplug the inverter, and i can turn on sleeper light and same thing. I can then sit for 3-4 hours reading or whatever and the truck will fire right off, no low voltage. anyone replace one of these? if so how much$$$?

 

oh yeah, just for the hell of it, I replaced all the batteries yesterday so thats not the problem

 

the only problem there is that if I do test the circuit, there's no telling where the drain is coming from. I would have to test EVERYTHING that draws on 12 volts. The sensor goes off when i turn on the lights, plug in the inverter, ect. I did fiddle with the panel in the sleeper, and it has stopped going off. I'm thinking loose connection in there or the panel itself is either shorting out or something. Anyone know if this is where the low voltage sensor is???

WHERE ARE YOU PABLO????????????????????
