I use a small alternator from a Suzuki Swift ’89 which should also fit to a Spiti.

I changed the pulley size to make it run slower.

 

Mine does work now 20 years.

 

Cheers

I'm getting tired of replacing the stock type alternators. They used to last a few seasons but now it seems like a few weekends is the norm.

 

 Like oil, I know there will be many different opinions, including running without one. That being said, any suggestions/part numbers/suppliers of a system that works for you?

 

BTW, I enjoyed watching the Jeff 500 last weekend on the VRG live stream (currently available on YouTube). Nice job against the 911 Mr. Frye.

 

thanks
