OK folks, I have been out there measuring and pulling wires....

The Onan (our is old remember an the Onan has its own battery) start battery has a 15~25ma drain when sitting. It should not and it didn't used to.....
I can measure this at terminal 11. If I have been out there pull the Molex and independently supply power at 11(+) and 1(-) the drain is not there. But if I plug the Molex and measure the drain at the fuse, it is there no matter what terminal I disconnect. This is below the sensitivity of my Bell/Fluke DC probe.

Fortunately, I have KenH's clearer diagram for help. (Thanks Ken)

Any Ideas??
