Just winterized the motorhome.
Ok.....it could be because my house batteries are in their 5th year. After all they are just two RV24-140 Marine Deep Cycle. We hardly ever dry camp, so they’re pretty much being charged when driving or we’re hooked up at camp. Never any 12 volt troubles with anything needing 12 volts.
Now, after unplugging from 50amps, in just 72 hours my house batteries measure 8.9 volts. The OEM battery switch is switched off. The Propane detector (hard wired to batteries) is off.
The awning and steps (hard wired to batteries) are retracted.
Anyone found anything else that draws on these batteries?
Guess I’ll buy new ones in the spring.
