Re: S1 80" Alternator install and battery
Excuse me if this reply comes up twice, bit of a problem with Google,
but I've waited all day to see if my first reply appeared.
Anyway, I've did the alternator mod on my 1952 2l 80 some years ago so
I can't remember the details but I'm pretty certain the dynamo pulley
will fit a Lucas alternator as the shafts are the same diameter. As to
mounting it I used a length of threaded rod (studding) for the top
mounts with an appropriate number of nuts and probably a bit of tube as
a spacer. I can't remember if I used the original adjustment bar, but
it's a simple enough thing to make one of the right length. I did use
the original belt.
If you'd like some photos let me know, our front wings are off at the
moment so photography would be easy.
My 80 is a trialer and at the time had an electric fan which is why I
fitted the alternator. For a road going vehicle I don't think I'd
bother, the dynamo is quite adequate for the low electrical load on an
S1. My road going 86 (also with electric fan) is still on the dynamo
and I think is only on it's second battery in 15 years or so.
