I’ve have just acquired a vixen plessey for my rb44
the vehicle had previously had a radio body fitted as it has the big generator and space for two large batteries in one of the left hand side lockers
firstly the batteries seemed to be wired into a box in that locker which has a kill switch in
they appear to be wired in paralell which would suggest to me that they are twelve volt
does the other black box transform that into 28 volt
