Hey everyone, I am having problems getting my '63 w/ 390 started. I got it started a week ago after it had sat for 5 months or so just by adding gas to carb. only took a couple cranks and it ran fine. Now I cant get spark to the plugs. It has an electric ignition and has always worked fine. I tested the coil and got what seemed to be ok readings for primary 1.6 ohms and secondary 10.7 I also replaced the condenser not too long ago. It seemed fine too when I put my multimeter on each end the reading steadily declined. I also tested the lead from coil to distributor. It had a resistance of 4.72 by itself and was reading 15.35 attached to coil/unplugged from dist. If I subtract the 4.72 from 15.35 you get 10.63 which is really close to 10.7 (reading of 2ndary coil). I have a spark plug tester light inserted between plug wire and plug and am getting nothing. I tried the old way too by pulling lead from coil to dist. and tried cranking it over and got no arc/spark there either. this has me confused as why reading seem ok but no spark when I hold it close to the cylinder head and crank engine. Does the reading of 4.72 seem high for just the wire itself?
Is something fried or going on in distributor cap. I don't know terminology for inside the dist. cap but there is a small nub in the center below where the coil wire comes in, it appears a bit dirty, but overall seems fine. Also the rotor has a metal tab mounted on top to contact that nub which also seems fine (only a small black dot from contact point).
Any ideas on what or how I can check dist. cap because everything leading to that point seems fine to me, but of course I could be overlooking something simple like the high tension lead. Shop manual says if the spark is good at high tension lead then the problem is probably in the cap or rotor. So why do I get an ok reading on the meter for the lead wire but no spark when cranking.
Manual also says if there is no spark at high tension lead than problem is most likely in the primary circuit (not sure what they are referring to) , bad lead (seemed to test ok) or coil (seemed to test ok). So what is the PRIMARY CIRCUIT?
Thanks in advance and sorry for such a long post
