I noticed that I am not always able to read the engine battery voltage on the panel's DC screen. The display defaults to the house batteries voltage. When I press the button on the panel's screen that's specific to showing the battery voltage (as opposed to water tanks levels or fuel tank level) it doesn't switch from house batteries to engine battery except when the engine battery voltage is below a certain value. Not sure what that value is but it seems the panel displays the engine battery voltage only when it's below 13V but does not display it if the engine battery voltage is close to 14V or more. Any clarification about this issue would be appreciated. Thank you.
I found the Scheiber panel just short of junk. It rarely read the fuel or water levels accurately unless you’re stationary and voltage always reads low… if at all. I got tired of the false low voltage alarms going off in the middle of the night so they are shut off. I bypassed the voltage shunt with a new one connected to a VERY accurate Blue Sea Systems M2 OLED Monitor. I know my usage rates for water & fuel fairly closely, so my guesses when refilling are pretty accurate now.
Hello Tafika II. Thanks for responding. I agree with what you say about the quality of the Scheiber panel readings. Where did you get the Blue Sea Systems OLED monitor from and does it provide the same type display for fuel and water levels? Would it work on the 2017 SO 389? Many thanks
