Snowmobike

So I am currently in the process of building a 1982 GS550. I removed the heavy and slow 550cc four banger and I fabricated to fit a rotax 521cc twin 2-stroke.

Engine runs good , used the jackshaft and snowmobile clutch so there is no shifting, just pin it and go. lol.

I am currently wiring the bike up. Pretty straight forward headlight, tail light, plate light, signals. I have a acewell speedo/tach fully digital even has fuel gauge.

But I am at a loss right now on converting from ac-dc. and keeping 12v

Does any one have electrical experience with this. I have a 12v Volatge Rectifier which gives me 12v dc but If I bring it above idle the volatage jumps to 20v. I also have ac voltage still 2-5v.

I ordered a aftermarket ski doo voltage regulator/rectifier Looks great ground, power out, and two power wires that come from the stator, but I am getting 2-6v when I need 12v-14v

Originally it just has a voltage regulator which works fine except for 1 thing, I need 12v dc for the acewell computer and for the flasher relay.

Unless there is a way to rectify voltage inline?

I hope I didnt loose anyone.

I ordered a different voltage regulator rectifier. I am thinking maybe the one I had has a internal problem. If the same thing happens with the new one then I'll rethink it.

The older skidoo rectifier is commonly used in refits to other machines because it's simple ,it works ,and it is cheap .Another good unit is the Polaris one .

So I think I found my problem is wiring the regulator rectifier. I didnt want to run a battery but I think that is where my problem is. I did a little research and I found out that in order for the regulator to work it needs to monitor the output dc voltage. which means it needs a 12v source like a battery to see a baseline. I will try to hook a battery inline and see if it makes a difference. If so maybe I can use a trailer battery or maybe even a large capacitor.
