New BAtteries Won' Charge

[MustangGT]

Hello All,
I am glad to be back. I missed all of you. Not all at one time though...
Situation: I have replaced my two house batteries and the chassis battery, but I can't get them to charge on shore power. they are hooked-up correctly, shore power was off while I was working on them and the Wizard electronic brain says it is in "boost" mode.
Even my little Battery Tender for the chassis battery is blinking green quickly.

thank you for any help!

Once you check obvious stuff like the disconnect switches, loose dirty or incorrect connections, fuses or relays I would start by checking the output of your converter, are you getting 13 plus volts from it?

Battery disconnect triggered or maybe defective auto reset circuit breaker often located near battery.

Battery Disconnect Switch ??

In-line Fuse on Battery Positive Cable??

Bad Ground?

Breaker open someplace?
I take it the voltage at the battery isn't 14.X even with the Wiz in boost?

You missed a wire or disturbed a loose ground.
