Hi Guys

My solution to a battery switch when I put the 261 in BEAUTY the C60S was a marine battery selector switch rated at 500 Amps continuous, 1000 Amps for 100 seconds. In my case I found a dual battery selector with a both off position. It allows me to run the truck on 6 volts and charge the 6 volt battery off the generated. If by chance I should have a problem starting then I flip the switch to the 12 volt battery (for the radios) hit the start which really spins over on the 12 volts.

Location on the Pattern 13 is on the underside of the cab floor under the drives side. If you go with a 6-12 volt battery approach try to find of a selector switch which does not have a both position for obvious reasons. If you are going with the auxiliary 12 volt then run the power supply to instruments etc to the 6 volt side of the switch and only connect the starter to the output of the switch.
Cheers Phil
