<VV> starting problems

Ah, an actual problem to answer...

You seem to have anabsence of voltage to the coil when the key is in th eON
position, but not the START position. While the ignition switch would be
the first suspect part, on an early the circuit that feeds the coil also
feeds everything else. So unless the radio, gen lights and oil lights don't
work, look in the engine compartment. The idiot lamps should be lit when
you first turn on the key.


With the key ON, measure the voltage at the + coil terminal. It should be
between 6 and 12 volts, depending on if the points are open or closed. 0 to
6 volts indicates a high resistance or open circuit. 
I don't have the diagram on me now, but look at the multiwire connector
near the battery. There should be a wire there with odd insulation, not
plastic alone. This is the resistor wire. See if there is voltage at this
end of the resitor wire. Should be 11 to 12 volts even with the points
closed at this point in the circuit. If 0 or so, clean the connector pins.
If no luck here, clean the connector under the dash that feeds this body
harness. If there is voltage at the connector, possibly the resistor wire
has opened (very rare) or it has become disconnected at one end (not so
rare).

Hope this helps.

My '63 Monza 900 'vert has developed a problem which I've been unable to 
diagnose. When attempting to start the engine it begins firing as though 
starting but as soon as I let off the key it dies.  If I continue 
holding the key in start position the engine will rev up but as soon as 
I release the key it dies.
I've checked the fuel pump and it seems to be working o.k. and I've also 
checked the ignition and found nothing.  I have a suspision it is in the 
electrical system but have run out of ideas.
Any suggestions would be greatly appreciated.
Clyde
