I am thinking of installing a cb and also an alarm into my the 1PZ but am a wee bit confused as to whether it runs on 24 volts or 12 volts.. the alarm compnay told me its 12 volt and the other battery is like a house battery.. but I think its 24 volts throughout???? anyway can somebody advise me on this and what do I need to do or how do I go about fitting a 12volt cb radio etc in??
Cheers for all you guys help so far:)

yours is a 24v system, have a look at the gauge on the dash

also yours has an inverter in the boot which is a step down to 12v so you can just wire to that if you want to run anything 12v

you can also check with a multi meter to see if its 12 or 24 power supply anywhere.

Thanks sorry bout the double posting
