Evenw ith the old Generator, I never really had any proble with mine.
But To note, that the "gen" light in the dash always did glow. I never
figured that one out....


A DC generator, unlike the alternators used today, only generates
power after a certain RPM threshold, caused by the counter EMF of the
battery. *There are no blocking diodes, so a generator is actually a
LOAD with current backing up through it at low speed....or, worse yet,
not turning at all, which cooks whichever rotor and commutator core it
happens to be sitting on at the time.


This is why old people are always so crazy about NOT leaving the key
on when their car isn't running. *The modern car, it makes no
difference. *The old cars, it cooked the generators and contact
ignition systems, killing the battery in the process.


My Guzzi Marelli problem was always switches, in the handle bars. *
They corroded in the rain and you rode in the dark or it wouldn't
run...or it wouldn't crank, and had no foot crank on it. *Replacing
the entire handle bar assembly including electrics with one from a
wrecked Honda 750 cured this problem for the rest of their lives.


I lost a starter, once. *It's core came apart. *Being in rural SC, my
only choice was an auto electric shop that looked like it had been in
business since rewinding Ford coils in the 1920's. *The owner, a nice
old guy, pulled it apart to look, shook his head we weren't gonna fix
that one and said, "This is just a Fiat starter running backwards. *
Let me pull the gear off the end of it and put it on a rebuilt Fiat
starter and you'll be fine. *You can't beat expertise in any field. *
He instructed his worker what to do, an hour later they had it mounted
back on my Guzzi and she cranked right up. *It was on there when I
sold it years later. *The points in its little distributor were also
the same as the Fiat rear engine Spider I also owned at the time.


There are rumors that FIAT is planning to re-enter the American
market...again.


I had a FIAT Abarth 850 for about three months once. Used. Awful car.
Now they are collector's items and fetch big bucks. They're still awful
cars.


But the prettiest awful car I ever had was an MG-A. Gorgeous, white with
red leather. Looked very pretty sitting in the driveway where I lived in
Kansas City. That's where it spent most of its time, too, sitting in the
driveway. It was a mechanical and electrical P.O.S. It was sort of like
the girl I was dating at the time...very pretty, with really nice
upholstery, but it was damned hard to start her up and keep her running..


Did you ever think it might be the operator and not the equipment?- Hide quoted text -

MG's and Triumphs were made to work on. Yes, they did have a lot of
tiny things go wrong with them. BUT, if you had even a tiny bit of
mechanical knowledge, they certainly wouldn't be sitting in your
driveway. Unless you were dumb enough to buy into someone else's
mechanical short comings.
