Dc volts readouts

[1ranger487vs]

I have a106 + 93 sv. 32 ffs. My question is my units show 11.5 and my input voltage is 12.8 right at the black box. Any idea

Too small of a wire, a bad connection or loose in the cradle. You can show 12v with no load, but when the load is there, it’s showing a weakness somewhere.

If you have the gls10 and graph on the same power cable, that could also do it. What size is the supply wire and is it directly to the battery?

I’m using 8 ga. From battery to gls 10. Have to check if I’m using same power. I checked the voltage going into the gls 10 and it was good

The voltage reading on the unit is the voltage under load of the unit only. Not the black box

I have both units hooked together. Would that make a difference. Both read same voltage

2 graphs and the module going through 8g should be plenty fine. If they were all to a 12g or smaller, I could see there maybe being some lower voltage readings.

Use a volt meter and check voltage at plug to the MFDs. If it’s low you need check your connections. As an example my power lead to my GLS 10 was bad. The crimps to the inline fuse had broken the wire inside the insulation. It took a minute to get that figured out.

I also agree with the above post. I have 8 gauge to a fuse panel. I run my LVS 34 and 2 106 SV’s on 10 ga coming off that panel to the bow. All my electronics run off of a 125 ah Ionic. I show 13.3 volts at the console and 13 volts at the bow.
