Help! ProNautic 1230P won’t charge

Installed new pronautic charger beginning of last season and it worked great all year. As I recall after wiring it in, setup was quite simple. I also added a new isolator at the time.
Got up to boat for the 1st time this season today to begin buffing. While there, I ran power to the boat, hooked up the house batteries, and port engine battery and turned on the charger breaker to charge them up after sitting in cold storage all winter. When I went down into the engine room to confirm everything was working, the blue light on the charger was on indicating AC power, and the Volts and Amps display both read 0. There were no fault lights on. Turned the breaker off and on a few times but no change. I left it and checked on it an hour later and blue light was still on, but Volt and Amp readings were both dark. I suspect they just time out. The reading at the breaker box for the house bank was 12.2, which from experience tells me about 12.3 at the batteries.

What am I doing wrong?

@Grahamu correct, I did not connect starboard battery. Was in hurry to get back to buffing. Pronautic directions indicate all charger outlets don’t need to sense a battery, those that do will still work. Not sure which battery terminal #1 goes to. When switching over from factory charger last year I moved the leads from old to new in same order. And it then worked fine all season.
She then turned the breaker OFF. I hooked up the 3rd battery bank (Generator and Starboard engine), then we turned on the breaker. Same result. ending in 0 volts and amps.
Then with breaker OFF I pushed in the 3 charger fuses in, (hoping to perhaps reset them if tripped), (they felt normal, not tripped), then turned breaker on, with same result, 0 volts and amps.
Then with breaker OFF, removed the temp sensor, turned breaker on, with same result, 0 volts and amps.
Now home, in looking through the manual, I do see something about returning the unit to "factory reset". In this mode I see the default battery type is "Sealed". My batteries are flooded. While this isn't mentioned in terms of fixing a problem, I can't think of anything else to try.
Any ideas?
Also, you don't have an open (un hooked ) battery connection do you?

The AC supply is protected by the breaker at the panel. The DC charge wires are protected by 70 amp fuses between the isolator and the battery.

If you look at the pic on pg 10 of the manual you can see the fuses on the right side

Mine didn't have yellow flags but they did have these black flags showing. I discovered that they swiveled. I played with them, hit the red buttons and checked voltage. Now I had one bank showing voltage. Aha!. Went back to fuses and learned pushing the red button pops the fuse, doesn't reset it. Once I pushed all 3 back up and did NOT touch the red button, I had voltage on all 3 banks, and the charger works fine.
I sensed all along it should be a simple fix, I was just too simple minded to figure it out on my own. This site is great. Thanks for all you help.
