ccw 400 rectifier

[crashingone2002]

Got the engine running and starting good (man this things fast for a newbie), now i just gotta get the charging system working. Looking at the drawings I'm seeing a rectifier. I don't have the rectifier, and there's not a snowmobile within 200 miles of here. lol Can a rectifier be made using diodes, or am i not thinking right here?

Can you verify that you have ac output from the charge coils? Usually 2 yellow wires coming out from behind the flywheel. Should get somewhere around 14-25 volts ac depending on rpm. I usually order universal rectifiers from Shade Tree. I can't find my book tonite but they have a web site. Probably need one that will handle more than 15 amps. I don't think the charge coils are above 15 amp.

Yep, I have ac from the two yellow wires that come from the charge coils. According to the drawing in the service manual it originally used a ccw part#43-0715-10 which looks like it has a 7.5 amp fuse built into it.

You can get aftermarket rectifier/regulators pretty cheaply. I'd try Manufacturers Supply. Most any unit made for a two stroke 12v system will work.

I would guess that pretty much any rectifier that rated for 25V or more at 25A or more ought to work, and give you enough margin to last a long time. That ought to just cost a buck or two. If you can't find one, let me know and I can mail you bridge rectifier module that will do what you need.

sweet! Thats the info i was looking for, and i assumed to be right but didnt want to take the chance of burning up a stator or battery. I think i can assemble one locally for scratch. Thanks!
