Engine SN: 2B019801
Mercmonitor Level II(?): 8M6001232
Setup:
I have an AGM for cranking/pumps/lights/etc., I'm adding a second 12V LFP for electronics, including my HDS' and NMEA 2k network.
Problem:
I've ran into strange voltage issues. I've figured out that when I hook up the LFP to all of the electronics if I go from the LFP hot to the house ground (which runs to the AGM and not the LFP) I get 12 volts ... WHEN THE AGM IS COMPLETELY DISCONNECTED. It should be 0 VDC.
I can remedy the problem by disconnecting the Mercmonitor which is powered through my NMEA 2k network. The network is powered by the LFP. The mercmonitor is the bridge causing the voltage issues.
Question:
Is there a way to keep my 2k network on the LFP and not give up the networking on my mercmonitor?
