So i am not loosing any amps and keeps my 6v blower motor from burning up but still keeps it blowing air like it should with the 6v system. i am putting a 1956 dodge 1/2 ton on a 85 ramcharger 4x4 frame and using the electrical system from that truck pic to follow from start to finsh when done. Thank for any help

The better way is with a regulator, but it will have to handle the current. That. How much current does the motor pull? I'm also with Andrew. Why not switch everything to 12v? If you ever find yourself in a fair fight, your tactics suck.

There are a lot of 6v regulators used for things like older motorcycles and you just need to put it in line with or at the fan. It doesn't matter if it's DC or AC volts as long as it doesn't exceed 6-volts and that's what a regulator does. We have bikes that run lights, cooling fans, turn signals, brake lights, etc, and have 6-volt bulbs and fans from a generator that povides 80+ AC volts but is regulated to 6 volts and there is no problem. Do a search for a 6 volt motorcycle regulator (without a rectifier) and IMO that should work. Here's a typical regulator as used on motorcycles:

And I have been looking for the 12v motor that i can't find. I bought a reducer but its only at half speed. Thanks all for your input i appreciate it . The last post sounds like the ticket to my problem im having
