LP2A Carrier Radio Installation

[Ron Pier]

Ian it makes no difference if you have one 12V battery or two 6V batteries as the two 6V batteries will be wired in series to create one 12V. As on my Tilly here for instance which is a normal 12V vehicle. Back then it was common to have both 6V and 12V vehicles so 6V batteries were quite common.

The two cables in the plug will be for the pos and neg terminals on the battery.

Ian, Does this help? and I might be corrected here.
The standard Universal carrier (MkI or MkI*) (English or Canadian) had a 6 volt battery on the left rear floor. It was a dedicated carrier battery for the starting and running of the carrier along with its standard fittings (lights , horn etc)
It also had a battery box at the rear that carried two 6 volt batteries that were dedicated radio batteries. These batteries were charged with the likes of a chore horse charger (6volt during WWII)
The batteries were obviously hooked up to the radio as an entirely independent circuit. They would possibly have been disconnected from the radio for charging (connected in parallel for charging and series for radio operation)
On later carriers like my Armoured O.P. MkIIIw, there was stowage provision for the gen set, on the left rear.
Also if it helps, the (later)19 set is rubber mounted. (I know very little about radios)
