24V question..

Post by **robbie** » Sat Apr 03, 2004 12:09 am

I just purchased a import patrol that is running 24V..

question is, if I mount in my 12V radio, will it blow up? do I need to put any 'filters' or anything in the wiring?

You will need a 24-12volt voltage reducer.Work out what 12v stuff you need to run. (AM\FM, UHF.CB ect) add a safety margin and all will be good. We use Redarc ones at work in earthmoving gear and have no problems.

I also bought an import partol about a month ago an when i put my cd player in there was one feed behind the cd player hole that was 12v. So I use that for my radios and cd player. Another problem i found was that to put an immobiliser in a 24v to 12v transformer had to be used and it cost a few more dollars, but now i got a 12v feed off that. I havent found any other probs yet...how bout yourself??

Some CAT (Big yellow things) 24v-12v reducers have a radio memory outlet for radios with memory. These arn't cheap, but top quality and small size.....

did you have both an accessories & constant power in 12V ? or was it just one 12V wire?

for the constant 12v for the stereo memory you can use a line from the 24V terminal and (a) a dropping resistor (cheapest but you have to do some maths) (b) a handful of diodes or a 12v Zener diode (less maths, more $) (c) a 12v solid state regulator (zero math, most cost).

even the regulator is only a few bucks.

So Brain Capability is inversely proportional to the cost of the part required.

I like that!

I think it's one of the immutable, unwritten laws of the universe.

The was a 12v accessory there, fuck knows whether or not it was factory or the happy jappy before me put it in but its there so i was happy. For spotlights you may have to use a 24v relay for them since the feed coming off the high bean will be 24v and would fry the 12v relays. I was cheering anyways cuz mine came with 24v IPF's. I contemplated putting my 12v spotties in properly with a relay but then i figured bah! a switch is close enough, good enough

you can just put 24V globes in any 12v lights.
