1999 Coachmen Santara 23rb (Class C) I few days ago I posted a question about my battery seeming not to charge when camped with shore power. I've been nosing around this, and I think I found the...

1. Measurements -- I reported "With external power and the battery disconnect switch in "use" position, there's 7.8V coming out of the converter into the battery.

This, I thought, would show me the output from the converter. Yes?
Are those measurements at the battery or the converter? Because no matter how messed up the converter might be, you should not be seeing 15.7v at the battery in the Store position. Now if it is at the converter, then maybe only the converter is bad.
2. When the Battery Disconnect switch ( Intellitec BD) js in the "store" position, the electric step still functions. All other 12V systems that I can find are off. Normal?
The step is probably wired to the chassis side, which is the best practice IMO. But no, if the converter is running, it should be providing the 12v for those other systems while the battery is disconnected via the switch.
4. I'm satisfied that the automatic cutover from shore power to generator is working. Is there any reason why I can't test this using generator power. I can do that in the storage yard, as opposed to driving the thing to a friend's house.
Yes, the generator power will be fine as a replacement for shore power.
