    Default No Spark in my '71

    I can't figure this one out. I just finished installing a new radiator, hoses, thermostat, etc. I flushed the whole system, and just replaced the coolant. All this took a few days.

    Today I tried starting it and it will not fire. I'm not getting any spark coming out of the coil. I've checked everything. I've gone through the Haynes Manual diagnostics and the coil, condensor, and coil wire all check out fine. But I'm still not getting spark.

    The only thing that I did to anything electrical system was to remove the heater blower in order to replace the heater hoses. I've not replaced it yet, and wasn't planning on doing so until I was sure there were no coolant leaks. There's no way that the heater is required to get spark is there? No way.

    Any ideas?

    With the points apart I get:
    I get 12V from the coil (+) lead to ground.
    I get 12V from the coil (-) lead to ground.
    I get 0V from the points to ground with the condensor wire removed.
    I get .005 OHMS from the coil to distributer wire.

    According to Haynes this means that I have no problems. Yet there is no spark leaving the coil. Any ideas????

    Default Points?

    Have you checked your points gap. If your points dont open and close to wont get a spark from the coil.

    Default Points are fine

    The points are fine, they are two months old, and although I did not check the gap last night, there was one (the voltage checks I did were with the points open). Allso, I didn't touch them since it was running last.

    What's the "good" ground that you're refering too?

    The only thing I can figure is that when I was flushing the block that the exist tube from the manifold shoots water right at the distributor. I had the cap on the entire time that water was near the engine. Afterwards I pulled the cap for over 24 hours to ensure any water that did get inside dried. Maybe something didn't like the water that much? Possibly the condenser? I have no idea.
