[Spridgets] Electrical help-Alternator conversion

[Linda Grunthaner]

Hi Mike and all Spridigeteers,
It was nice to see this pdf with Frank's post regarding converting our
Spridgets to alternators as I may do this same in the future buy my 1275 in
my 62 deep pink Sprite is still running stock for now. My question is, who
is running the PDLJMPR (known as "Puddle Jumper'') web magazine?
https://pdljmpr.tripod.com/contents.htm. I was surprised to see it still up
and running. My second question is, who is running "Sprite Spot" as the
photos are long gone for many years but some elements still remain
although unsecured, http://www.spritespot.com.
Happy and safe motoring,
Linda
62 California Sprite "Pinky"
