Electric Pattern

[Bill Glaze]

I can't imagine burning out a perfectly good alternator that is rated
for 100 amps by just charging a battery.  I've done it so many times.
Yet, I suppose if there was something else going on, it sure could
happen.  I mean, this mechanic said he's seen it.  It's just hard to
imagine--my alternators put out ~14.7 volts x 100 amps. = 1,470 watts.
Lots of current.  Last time I looked, that's more than a large TV uses,
or even a 2 slice toaster.  I'd like to know what the DC current draw is
on Jason's chargers.)
Oh, Well.
