Mine is a '98 Lance Lite (similar to yours) and I did have a battery problem since all three of my batteries are always hooked up.-and all the same group 27 battery. It would take three months if I left everything hooked up and parked for the batts to go south. This is without a battery minder. I think the CO2 sensor and main power module in the TC do have a parasitic drain happening.
The fix was to simply disconnect both batt. cables from in the TC compartment and a battery isolator from the two truck batteries. No more woes, except I must remember to hook the TC batt. back up. I use a batt. minder on the cable-free TC batt. The battery with the minder MUST be at full charge before using the minder.
While on the road, I have no battery problems, unless i leave the fridge on 12V in camp, then the batts are flat after 6 or 7 hours. How would I know that?
Let us know what you come up with. Keep the faith, baby, the solution is right around the corner.
regards, as always, jefe
