[geeks] argh!/car electrics

Jon,

WRT Car electrics, it may very well be that your radio is getting it's ground connection from the chassis (the case of the radio, when physically attached to the frame of the car, gives it a ground connection.

Thanks,

Ken

I found it... was under some rags in the garage.

But I have a working ammeter in the '58 now :)
I think it's working. When I turn different
gizmos on (lights, heater) the needle moves.

I also found a bunch of wires that do
certain things.... one comes on when I
turn the lights on... it goes to a
non-existant auxillary light in the cockpit.

I found the lead that goes to the clock. I
hooked it up and the clock is still broken.
I also found that the 'extra' light bulb 
hanging behind the dash actually goes to
the clock and the wire connecting to the
bulb gets hot when the lights are turned on.

I found two more leads (one yellow, one brown)
which come on when the ignition is on.

The AM-only Wonderbar Radio had a molex
connector... one is 12v always on, and
the other... well, the other isn't
a ground, it's white and seems to have
trace voltages in it from time to time.
Maybe something that's supposed to be a
ground which is disconnected? No, it's
not the antenna, that actually has the
standard GM antenna connector. It's
weird.

I'm just surprised what's still left
under there (there's about a half-dozen
wires which seem to have been randomly
cut over the years) still works as well
as it does...
