Hi All,
Our 1997 190P has the original electrical setup. Coach battery is antiquated EverStart 24DC -- pretty much dead. This was not an issue due to very limited use of the 190P until recently when 8 YO chassis battery died. Then a replacement chassis Interstate Group 27 battery drained in a week or so while in storage (unsure if I had mistakenly left house system and lights on). So I monitored the second chassis replacement and voltage dropped to under 12 while parked for a few days, this time definitely with house power off. As a test, I disconnected house battery leads and monitored chassis battery which, this time, held normal voltage. Also, even with leads off of house battery, I can turn on house power and indeed house lights work! I am not electrical savvy, but am assuming this all means the isolator is not protecting the chassis battery. Would any of you enlightened chime in. Much appreciated.
The under hood (red) isolator 'appears' to be labeled Powerline 22-16 PL1-130-2. I say 'appears' as the isolator label is on firewall side and hard to get a clear photo. Before I replace house battery, should I replace the isolator or is there some other explanation of chassis battery drain. If isolator has to be replaced, search suggests the Powerline is no longer available, one post suggesting Victron Energy Argofet Isolator 200-2AC (but that raises the issue as to which Victron output lead is house vs chassis and what to do with Victron's 'ground' that has no counterpart on the Powerline.
The existing house battery 24DC probably serves our needs, but if anyone has suggestion of upgrade for battery and charging, now would be time to consider, so please chime in.
