12volt stepdown from 36 volt system??

Does the cart use 1 36 volt battery or 3 12 volt batteries in series.

If it uses 3 in series, your best bet may be to hook the radio to one battery, the one that has it's negative terminal connected to ground.

Hi, Or if the current draw of the radio is know, installing drop resistor of correct value and Wattage. Calculate with Ohm's law. Tony

That will not work because a load like a radio is variable. But it probably does run off 12 volt batteries, so like the first guy said, just hook it up to one of them. Greg

It's not worth the effort.

Buy a portable radio that uses "D" cells, and duct tape it to the cart

With continuous use, you might have to change batterys every six months or so.

There are simple voltage regulator circuits that one can build with parts from Radio Schack. A couple of connectors, a board, a 12 volt regulator and some capacitors ought to get you going. You could probably even ditch the board. Of course, make sure you put a fuse from the battery to the regulator.

If he couldn't tap into a 12V source, a simple voltage divider and a fuse should work .

These carts use six 6-volt batteries. I hooked my 12 volt light system up by connecting across two of the batteries.
