12v to 24volts?

[billy]

I am looking for something that will turn 12 volts into 24volts just so I can run the fresh air vent blowers.
Either that or find a 12v motor i can swap into the housing

Would this work?

as long as it doesn't pull more than 10 amp.

Fans will probably pull 30 amps or more, so I doubt that would work. You should be able to find a 12 volt motor that will swap in.

Thanks for the input.
the truck has two of these blowers and i for sure want them operational.
I am going to have to pull one and take measurements as well as amps,volts

12-24 volts

get a hemmings book look thru and find the automotive electric section. find one that does heater, vent motors. drop some coins on a phone call.

You could put another battery in series for just the fan to bring up the voltage.

I still dont understand how to connect them in series and tandem and 12 volt and 24 volt all at the same time

Have you tried running them on 12 volts. They might run just slower.

If all your running is a fan, use a motorcycle battery for the second battery wired in series.

Cool beans!!!

Dual batteries here we come.
I have wanted more cold cranking amps anyways

 

[billy]

How do i wire it so I can be charging both 12v batteries?
I am sure you guys know.
Ya seem ta know everything else!

 

[sneakysnake]

Actually you'll be only using the main battery and the other will charge as the fan is used, otherwise it will be isolated. you could use a relay to charge but I'm not going to get you confused.

My buddy here is a pretty smart cookie
I bet he comes up with sumpin

 

[Willowbilly3]

Won't he need a series/parallel switch or a battery isolater to keep the second battery charged?
Billy, I think just pull one of those motors and head down to the parts store. They generally have universal fit blower motors and I bet you can match something up in 12 volt. That's where I would start anyway. Ot maybe try hitting a junkyard with some old school busses. They have big mongo twin fan heaters in the back, maybe just pirate the whole thing.

In Alaska, I always saved those optional rear seat heaters from any vans I parted out. They are a stand alone box type thing.
Something like this

But what would really be kick butt is a wood stove with a chimney out the roof.[ddd
