Replaced the Univolt where does the white wire go?

Where is the Power On light located?

My power on light is on the "control panel". So is the ammeter. I too have that little fuse in my fuse panel. I have disabled my control panel as I no longer need it.

House battery positive.

Fuse panel positive.
Charge line from TV positive.

In order to get the ammeter to function you will need to wire the shunt in series with the negative side of the system. Along with running 2 wires (which should exist) to the shunt from the meter. Note the 2 small (red and black) at the bottom of the shunt.
I don't have a control panel in my coach. So can't be of help there. Don't know what is on an old control panel. If you use the shunt it must be mounted on an isolated surface.

So to pare this down a bit, I should be connecting the #8 blue stranded (TV charge) to the + lug next to battery + (red in photo of new converter), and the #8 white stranded (main chassis ground labeled as load?) to the - lug with black and white wires in it at bottom of pic of new unit? I will use a 40 amp fuse on the TV charge line.

My apologies for the new unit pic being upside down. I uploaded it 4x with editing it to be showing both ways before uploading and it still shows inverted.

For the control panel, I presume I can just run the grey “power on” lead to one of the 12v outputs with a 4 amp fuse?

The “shunt” is what I’m not sure on. Do people typically drill out the rivets on the univolt and remove the metal plate the small red and black wires go to? I’m reading this as the ammeter? I would like the control panel to be fully functional, but I usually install a USB charger that has an LED volt meter built in so the ammeter would be surplus, and I could live with it not working.

That makes the old Univolt pic above look like the dinosaur it is. Got the new panel mounted in the closet wall and the disconnect switch installed. All DC lights and pump now work. AC outlets work and even the ammeter works and most of it works except the power on light. Progress..

Hi my old set up is exactly like the one in THE photo. Just want to make sure where the thick white wire that was attached to the LOAD-WHITE should go . To the negative on the new fuse panel or to the chassis for a ground?
Also what did you do with the old inline fuses that attached to the copper plate? Do I need really them?
TIA

Did anyone ever figure out where the Load White Wire should go when replacing the Univolt? Replacing it with a Best Converter.
