Ok this is the problem I have got. I have got power to my coil but no power going to the points from the coil. Can anyone help out here. It is still 6 volt to. It ran fine last Wed. evening. We put another coil on it and it does the samething. Checked the wires and nothing seems to have a break in them. I'm up for any help at this point. Thanks Scott

 

Did you check the wire from the coil to the stud on the side of the distributor and then from the stud on the inside of the coil to the top of the points? The wire on the inside can ground out inside the distributor. I've had the wire inside either break or ground out inside my distributors on both the six in my F-2 and the flattie in my panel. It can happen fast, one minute it's working fine, the next nothing.

 

No I didn't, I forgot about that wire. Thank you very much, I will check this wire also. Thanks Scott

 

Forgot to mention I have power to the Positive side of the coil but "NO" power from the negitive side of the coil that goes to the distributer, therefore getting no power to the points. I'll still check the other wire though. Thanks Scott

 

i'd like to refresh this thread as i'm having the exact same issue but with a 12V system. I've replaced: ignition coil, condenser, points, coil to dist wire, both wires (+ and ground) IN the dist cup, rotor, cap, all dist wires including coil to center of cap. I've confirmed i'm not grounding out in the dist but the inline spark indicator (things with lightbulbs) placed between the spark plugs and cap dont light up.
A chevy guy I know suggested checking the distributor is not in at 180 degrees, but i would still think i should see something light up. According to the pictures i've found the vacuum advance on a '49 226 should point toward the front of the truck, which is how mine is placed. I've been dinking with this for over a month now, asked multiple questions and am to the point of being ready to higher a mechanic to take a look. Any suggestions on what to do next would be very appreciated.

 

I will see what my dad did to the truck while I was at work. I come home yesterday and he got it running. It starts up on the 2nd or 3rd crank he said. I'll see what I can do and get back with you. Scott

 

did you check the inline resistor? (porcelain block with two posts, usually on firewall). might have a break on underside.

 

sorry i never updated this thread... Petey you are correct. The issue was that in my ignorance I did not know that a ballast resistor was needed on most ignition coils thus when testing the coil burned up. Julie does not have this in her diagrams as she went with a MSD ignition and more expensive coil that does not need one.
So after putting in another new coil and adding the resistor, i have spark! and in fact did get it to start with a bit of gas and ether put down the carb

 

Links Vette I have a 226 CI "H" block and have been watching the threads about converting to 12 volt. can you tell me what parts you installed and where you found them to make the conversion. I understand that you changed out the points condenser and coil and am wondering if you still have the part numbers. Same for the alternator and frankly any other part numbers. Thank sfor all the questions and answers in the various posts you have made.
