I am out on a short 5 day trip, and stayed at a KOA for 2 days plugged in to 50 amp. No issues noted. While leaving this morning when I turned the key to retract the slides, I noted a yellow "MIL" light on the dash. Rig started and ran fine, no issues besides the MIL light.
Got to the next campground in AZ about 3 hours later and plugged in to 50 amp. After setting up I opened the VMSpc and checked the diagnostic history. The trouble code that was saved looked very familiar. 1081 31 Unknown Issue. I used to get that code all the time before I put the Amp-L-Start in the battery bay. It was due to the low voltage in the chassis batteries from the charging algorithm Spyder uses to charge the chassis batteries.
I looked at the Magnum remote above the seat and the State of Charge (SOC) of the house bank was 100%. Checking the status of the house and chassis batteries, the house bank showed charging at 14.8 volts, and the chassis was sitting at 13.8 volts.
Going to the house bank and checking the status of the Amp-L-Start mounted on the wall, two of the red LED's were blinking indicating "high voltage" from the house bank. Getting close to them I could hear the house batteries charging by the electrolyte bubbling rapidly.
Checking my Coach Proxy on my phone, the house bank still showed at 14.8 volts. I came in and checked and the Magnum remote was still showing 100% SOC. I pushed the "Charger" button on the Remote Panel, putting the charger in standby mode. Almost immediately the voltage on the house bank began to decrease. That was about 30-45 minutes ago, and the house bank is showing 12.6 volts and the chassis is at 12.9. When I went back to check the Amp-L-Start, the blinking red LED's were off, and the green "maintainer" LED was lit.
While outside I checked the network cables to the BMK and shunt, and all are tight and secure. Unplugging the network cable caused the LED on the BMK to start to blink. Reinserting the network cable caused it to glow solid.
I am at a loss to figure out why the Magnum was pushing so much voltage to the house bank. I recently watered and cleaned the battery connections before I went on a 4 day trip to Quartzsite dry camping. All batteries and systems worked normally. I checked the settings on the Magnum, and all seem to be set up normally.
Any guesses on where to look or what to try? I scanned the BMK manual, but saw nothing indicating what might cause that issue.
