    The straight 8 in my 39 Pontiac is not getting spark across the points. It has 6 volts from the coil terminal down to the distributor terminal but I don't get anything across the points, thus no spark.
    What do I need to check?

    Can you watch and see if it’s throwing a blue spark? Under the cap, could be a capacitor but seems more likely just dirty points?

    Do you have 6 volts at the connector on the points? Does the distributor have a good ground? If you close the points, does the voltage go to zero? If it doesn't and you have 6 volts at the point connector, it points to a bad ground.

    I will check that out tomorrow after I get home from my orthopedic Doctor's appointment. I tried to move a boat trailer, on jack stands, sideways with just the sudden hard impact of the top of my head.It kinda squished a coupe vertebrae in my neck.

    Trailer is fine. My neck, not so much. Basically down to bone on bone in C-2, 3 and 4. Getting old ain't for sissies!:D I got side tracked and haven't had a chance to check the car yet. I don't need to really worry about it because it will be the new owners problem in about a week!

    The car is the new owners problem now. He was excited that the motor turned over on battery power. I showed him a short video of me driving it around the yard. I thought I had a parking brake to slow it down. I was only going about 10mph but the emergency brake failed and I used the radiator and cedar tree stump to stop the car. I did kill the ignition but that didn't slow the beast down. Luckily, I had pulled the original radiator and put in an odd ball that held water. The car smoked, but that was because I had soaked the cylinders with Marvel Mystery Oil for a week or so prior to starting it.
