This solid state rectifier is suitable for alternator.equipped models.I will post this the day you make payment by first class post.I post every day including weekends.
These will always be in stock and will never run out.
Not to be confused with lower cost items listed with no visible writing to disguise they are the very cheap KBPC 5010 type.The type i supply have been in use on classic bikes for well over 30 years and are a proven solution for replacing the original rectifier.
I will include a small drawing which explains what each pin on the rectifier does.
There are good drawings on a Google search for Ariel bikes..
Selling for 15 years on ebay  and i do have my own classic bikes.
