I removed Battery 2 (House Batteries & Starboard) from the isolator and bolted the two wires together and that helped when I don't have the AC Converter on. So I think I also have a second issue with the AC converter.
I think it's a bad isolator because here are the following test results. I turned of the ac converter and ran the fridge on house battery and the bilge blowers for 10 minutes the Port 12.9 volts and the Starboard (house battery) battery was 12.7 volts.
I started Starboard engine only, and the...
Thanks, I'll try that, but when I test voltage with my meter it's about 13.8 vdc without the engine running When I start both engines the on the starboard engine voltage drops and continues to drop until it starved my house on low voltage.
I have a 95 370 Sundancer and the voltage on the Starboard is always low. I have had the alternators tested and are working properly, but had to come home the other night holding the Emergency Start button to charge the Starboard engine. Once I plugged into shore power and the AC converter...
