AN/VIC-4, and adding switched 12V/24V to the M35

[Saar]

Here's some info on how to rig up your own sources of 12VDC and 24VDC which are switched by the vehicle's main power switch and include a battery equalizer. Also shown is the VIC-4 intercom system about to be installed. Contact me if you want a schematic fo the power arrangement.

I recently thought I was purchasing an advertised AM1780 VIC1 and have discovered it looked different than I remembered. Long story short it's a VIC4 M981 so it will not work with my control boxes. Anyone have any boxes that will work or is there a fix to make this work. Otherwise I guess I will sell it and try again.
