Re: [T3] got 'er going, now she's dead again

I couldn't stand it so I braved the rain and did some tests with the car.
I'm getting 6V to the coil but I'm guessing that's correct in a 6V system (I
forgot to mention that.)  When I open and close the points I'm getting a
spark.  I hooked up the timing light again and maybe I was doing it wrong
before.  I do get a flash now and then, but it's really erratic and
infrequent.  Grounding the wire seems to increase the frequency of flashes a
little bit but it is still only now and then that it flashes.  Interestingly
there is regular spark happening where the end of the wire is grounding.

I'm glad I did this at night now that I think about it.

So what conclusions can be drawn from this?
