cr 500 carb heater wiring

[preclatton]

working on installing the KTM carb heater on my CR500 snowbike.
For power I am going with a lighting stator from Ricky Stator (45W).
My question is if I can go from that directly to the carb heater (20W), or do I need to install a AC regulator as well? Any help would be good. I want the carb heater to work good and not fail, so I am thinking a regulator might be needed, but I am not sure.

I have the Service Honda ignition/stator. U can get it with a AC or DC regulator/rectifier. I chose DC Rectifier. You can connect that straight to the ktm carb heater. Some say you cant but MtnDoo set his up that way. I am going to run a small NiMh 12v 4000mah battery since im going to run a Solstice HID.

Okay, so you are using a regulator / rectifier, and then going from there to the carb heater. Does anyone know if just a AC regulator would work, or does the AC power need converted to DC with the rectifier to work with the carb heater?

I've done some more research and it sounds like I can run just an AC regulator for this application. However, I need to confirm that the carb heater will run on AC power. Does anyone know if it will run on AC power?

Clayton the coils are only 25 watt so I don't think we will have to regulate the output.

Okay, your right, I don't know why I was thinking 45w. It seems like some of the other guys are using a regulator/rectifier to convert it to DC. You think we are fine to run it on AC?

You should be able top use either AC or DC. Just depends on the system you have. I chose DC for the type of system I'm building.

Yes, you can use pwr from your AC source. No rectifier required, no battery required. They will both power your KTM heater the same. AC is more efficient straight from your coil. I reg/ rec mine in the air box, then straight to the heater for other options, but I never needed or used them. If you want to run a light or any other stuff, reg/rec your pwr in the air box then go where ever you need from there. No battery required. If you only need carb heat, I would pull from my AC source directly with a simple rocker switch.

Thanks for the replies. Mtndoo do you think I need to run an AC regulator? Or just go direct. I don't want to overpower the heater and burn out the heater. Everything else makes perfect sense. Thanks for your help.
