Was wondering if someone could help me out here, I was going to convert my 1948 Chevy convertible to
12 Volts and it's currently 6 Volts and I don't know what to do with the convertible pump. How do I drop the voltage once I buy a voltage reducer, or can I leave at 12 V?

I've not done a conversion on a convertible so I have no first hand experience but there are a few general guidelines. You will likely need to put a voltage reducer on the pump. Reducers are not all equal. You'll need to find one that has the capacity to handle the amperage draw of the pump. The same goes for your heater/defroster fan. I'll move this to the 6 volt electrical forum for you where you'll likely find a wider audience.

Tiny is right on target about matching the capacity of the voltage reducer to the amperage draw of the motor. I would use separate reducers for the fan and top motors. Otherwise you can damage the motor or even create a fire.

Hey guys, I really appreciate all this information on this website and you guys are great. I'm just barely getting used to page. I really appreciate the feedback and everybody's help. Once again, I have a few more questions number one does anybody know how many amps the convertible 48 Chevy pump draws so I can find the right reducer. Also, if I do decide to make it 12 V because of the radio air system and so forth is there any other advice someone can possibly give me on how to work on the convertible pump meaning, electrical wise.

Anything electrical that is designed to operate on 6v will likely need a voltage reducer to operate correctly on 12 volts. Any 6v device will draw double the amperage of a 12v (ohms law) so pay attention to wire gauge if you replace any wiring and keep the 6v device. Normally 6v wiring will have no problems handling any 12v device. I don't have the reference material to be able to tell you the amperage draw of the pump motor. Hopefully someone will be able to help.
