<VV> 64 run circuit problem

[Hugo Miller]

That's why I cautioned against using a voltmeter - if you have a poor 
connection there or anywhere else, the voltmeter won't show it. You need 
enough current to power a decent size bulb (headlamp or stop lamp) to be 
sure the coil is going to deliver a spark. Testing the circuit with a 
bulb is more reliable than a voltmeter.
