Hello all, I'm finishing restoration on my 77 Camper and was wondering if anyone was familiar with the aux volts/fuel volts switch. What position should they be in?

Also, does anyone else have these switches in front of the throttle? It's a push button and to rocker switches. I was told the depth charge lever is for nuetral throttle control the others dont work and I have no clue.

Thanks in advance for any help!
