I have a mr buddy heater with a Built I 6 volt blower fan. I want to plug
this into any 12 volt receptacle around the boat. I bought and wired a circuit with a reducer from radio
shack that was rated to 1 amp. It worked twice. The temperature was sixty and now it's zero outside. The fan is rated to draw 900ma. I think that regulator
is not rated high enough, is that why it stopped working? When I plug
it in now All you here is a buzz as though the fan is trying to start.
I bought a 3 amp rated product from bwd auto part manufacturing and the wiring
schematic is counterintuitive, even though I called the manufacturer. The schematic shows that if the amp load is 1, I need 4 vr1 voltage reducers wired in series. If the draw is 2, I need 2 vr1s. 4 amp draw and I need 1 voltage reducer. The tech guy at bwd said I can try using one reducer but should check the circuit with a multimeter.
What should I check, the voltage coming out or the ohms or both. If I wire this up and the volts read 6, can I use it or would it damage the fan?
Am I making this too complicated? Is there a simpler solution? Moving the boat from Lake Superior
to the exumas
isn't out of the question.
