Thomas Minotour battery drain

Hello all,

Iím having problems with battery drain. I did a little poking around and found LED 5 on fuse block 2 lit up with the bus completely off and closed up. When I open the passenger door, the LED gets brighter. I always thought that LEDs are binary, either on or off, but thatís what Iím seeing. The legend on the fuse cabinet says that LED means the door is open. I found the switch in the manual door opener lever case and unplugged it, but the light is still glowing half-bright.

I know that itís a pretty rare event that someone else experiences the same short to ground, but who knows? If youíve had this problem before, please let me know and if you figured out the problem, that would be even better!

Can you pull the fuse that controls the LED?
If so, then check around to find out what isn't working?

Had a Jaguar with a similar parasitic draw that killed my battery in short order and long story short, I was able to pull fuses until the problem was discovered. Turned out to be faulty seat heater.

Good luck on finding your "issue"...
