bmv 712 starter low voltage starter battery

I just installed a BMV 712 on my boat.

I'm reading the service batteries correctly, but the starter battery gives me a very low reading of 10.51 v.

If I do the measurement with a multimeter, I get a correct reading of +/- 13.6 v.

The starter battery always gives me a reading of about 2.5 v less than what the multimeter indicates and is at 100% charge.

I have read some similar issues with a fuse problems

Could that be the problem with the discrepancy?


Thank you

Change out the red wiring with the fuse. I have found them to be faulty from the factory.
