The chassis battery read 9volts, so I put it on the charger. Replaced the battery, and the coach started, and window shade retracted. Using a voltmeter on the SDC-107A BCC, I do not see any voltage on the lug for the chassis battery. I do of course when the coach is running as this is coming from the engine generator. When running on shore power, there is no voltage on that lug. The chassis batteries show 13.25 volts, so the interconnect relay should energize putting the coach and chassis batteries in parallel. This does not appear to work.
Yes the steps extend and retract. I'm pretty confident the chassis batteries are good. They appear to be charged ok by the converter.
