m109a4 panel boxes

[scottmh]

What are the panel boxes inside the van of a m109a4? One is a big on off throw switch the. Two circuit breakers and then a box with a switch from 24 colts to 115volts. Is that some kind of inverter? None of mine seem to do anything

Where did you find the tech manual for the M109A4? All I can find is for the M35's…
Thanks for any help you can provide.
