Re: Twelve Volt Conversions

For the OD I would suggest something like this converter which is specifically motor and coil rated. If you check out their store they have several other units varying in capacity but for OD 25amp is as low as I would go. They have a 30 and a 40 amp unit which might be better as you could run a separate power supply for powering the original radio, heater and OD.

There was another vendor who had something similar but he doesn't seem to have his products available now. This converter is close in function but smaller in physical size. Unlike the other vendor I don't see where this one says specifically the units can be hooked up and work with positive ground cars. A few of the large 50 amp units on the website do say negative only but this one does not. With your alternator, possibly the car has already been polarity swapped and a moot point. If not and you are interested you might need to inquire if it will work in a positive ground car. I wouldn't be surprised if a vendor in Australia didn't have something similar.
