Regulator cuts out at high rpm

My Balmer Max Change 612 goes dark between 1000 and 2000 rpm. It works great at idle and low rpm, but then cuts out.

I've had three marine electricians look at it and haven't been able to figure it out. Also spent a good deal of time on the phone with Balmer, but no solutions. I've even replaced the unit, and still the same, so I figure it's in the wiring.

I just installed solar panels to help boost power and they work great. Yesterday, the panels brought my batteries up to 13.90, but then I started the engine to anchor and noticed after I shut the engine down, the batteries were down to 12.80. Why would I lose power on the house bank? Seems strange.

Don't know if these two are related, but if anyone has any ideas, I'd love to hear them. Thanks.

I don't know about the Balmar, but lead acid batteries fully charged usually read about 12.6 V, except immediately after they have been charging. So if you charge them fully at say 13.6V, remove the charging source, switch on some lights for a couple of minutes, then off again, expect to see about 12.6 V.
