When I was troubleshooting my lock problem, I got the wires on the door contact reversed and that fuse by the battery blew!!!!!!! If I had taken the jamb side off, I would of seen the colors, red and black both sides. So then I had to troubleshoot the 12v supply. I believe it was one of the reverse polarity fuses. I read about that one being on the frame behind the battery several times. At least I was at homeworking on it.
There is a difference between a 12 volt SUPPLY on those 2 pins and a 12 volt actuator supply at those 2 pins. 99% of Door pins are for the ACTUATOR wires to the door motor and will NOT blow any fuse as I stated are just reverse polarity if connected backwards. SOME door locks, usually Towables use a 12 volt supply as the complete system is inside the door itself. Trimark systems do not do that on motorhomes. Doug
