Link 10 showing 0.05V on a voltage reading.

Amps and amp-hours show correct numbers. But Voltage display shows 0.05V.
I have numerous other voltage indicators, like on solar controller, engine instrument panel, battery switch LED bar and they all indicate correct voltage readings anywhere from 12.2-15V depending on the state of charging.

I checked two fuses located in yellow fuse holders I guess one of them would be voltage sense wire. they are ok.
I also checked that all leads terminating in the back of link 10 are connected. They seem to be ok.
Is there a way to reset the unit?
I guess link 10 and link 20 would be similar the only difference being one vs. 2 house banks.

There is a place on the back of the unit where one could solder a serial connector like RS232, i suppose this thing must have provision for interfacing to laptop. If anyone has done that, details would be greatly appreciated.

Did this condition come on suddenly or has the voltage reading slowly been deteriorating?

Re: Link 10 showing 0.05V on a voltage reading.

When you checked the fuses did you really check them or just look at them? I have a Victron monitor and the in line fuse went bad. Visually it was perfect but I measured the voltage across the fuse itself and it became obvious that it was actually defective.

It went bad at once.
Good point about the fuse, I only visually checked it. I had another fuse this spring appear ok visually, but it was actually open circuited. I'll check that out with an ohm meter. Thanks!
I rewired the entire boat in 2004, I guess 8 years and fuses should be tossed, replaced with fresh ones.

Re: Link 10 showing 0.05V on a voltage reading.

Fuse holders, especially the expensive type, will also develop corrosion through their very thinly plated contact areas and cause gremlin problems.

In your case, check for voltage at the appropriate connection at the Link readout unit to quickly determine if you have a problem in the circuit.

Re: Link 10 showing 0.05V on a voltage reading.

Fuseholders are notorious for failing in addition to the fuses where they connect at the ends. A few weeks ago our engine wouldn't start so I simply went to the fuseholder to the starter solenoid, wiped the ends of the fuse and we were back in business. Guess a breaker would be better but they don't come in smaller amperages. You could just jumper the fuseholer and assure yourself that that is the issue.

It was a fuse. For some reason it didn't look blown but it was open circuited. Voltage reading is working again. Thanks.
