yeh, thats correct. if ya need 12V drastically, connect up to the one on the drivers side only. but dont do that permanantly, youll kill ya batteries

Get a 24v - 12v trannie guru. I've got one in my safari shorty and it goes alright. Have to agree with hooking things up to one battery though, you do kill them. I have a cigi lighter spot and a couple of other things and I have to charge my batteries with a car charger occasionally. Yes I could fix the problem, but to be honest I couldnt be bothered :D

thanks guys...

ive identified the dodgy battery and swapped it with another - now before i hook it back up.... im second guessing myself now -

negative on the driver side battery goes to ground
positive on the driver side battery goes to negative on the passenger side battery
positive on the passenger side battery is power out.

correct?

Did you find the factory one in the passangers side kick panel? Rated at 10 amps but more like 5 i reckon.

Hmmmm, mines the opposite. Passengers neg to ground, positive through to drivers side negative, and drivers side positive is your 24v feed.

I'm running 3 converters, the factory feeds the now 12v cig. socket, an after market one feeds stereo etc, and the third is mainly a back up.
If either of the other 2 blow, I have it wired to tap straight into the wiring of the others.

I am sure you can get 12volts of a 24volt system if the system is using two 12 volt batteries by using one terminal on one battery and another terminal on the other battery. Use a volt metre to find out.

24volt systems

Post by mgundle »

being an auto elec i have found a nifty readarc product called a charge equilizer which will guarantee same applied voltages to each battery lets say 13.6 each when running
very good if you get just one dead battery all the time with no draw off it
bout 250 bucks well worth it
