PM me with your email address and I'll send you a pdf on the 12v conversion.
Is there any particular reason to do this as there is no problems running the 24volt setup. I run with the 24volt system over here with no problems and use it to jump start all sorts of equipment from big rigs to scissor lifts etc.
I have all my accessories (6 spotlights, Beacons, CB etc etc) wired to the second battery to even up the load on each alternator and battery.
I also removed the blackout driving lamp and fitted a second stinger plug wired for 12 volts and fitted heavy duty croc clips to one end of my stinger leads(jump leads).
regards from Scotland
