Default No Spark

I am having a problem and I have tried almost everything to correct it. I do not get a spark when I try to start my 1966 I6. I have a new battery, new distributer, new dist. cap, new plugs and wire. I have tested the wires. It appears that I am not getting any fire from the hot wire that is connected to the coil. I have a new coil. Has anyone had this problem and can you tell me what you did to fix it. I am open to suggestions.

OK, are you absolutely sure you have the (BAT.) battery or (+) plus on the coil hooked up to the battery? The negative (-) or ALT side of the coil goes to the distributor for the points. Get back afteryou double check this.

As a trouble shooting technique, put a jumper wire from the battery to the coil and try to start the car. DO NOT KEEP THIS JUMPER IN PLACE FOR ANY LENGTH OF TIME WHILE RUNNING. Your coil uses 6-8 V to operate via a resistance wire from the ignition switch to the coil. When in the start mode, 12 V is applied by the solenoid directly to the coil only while the starter is engaged. If it starts, it's the 12 V wiring, if it don't, it's the coil or distributor. And check to see if number one cylinder is at top dead center, not 180 deg out.

Actually, the coil should register over 9 volts at the + side of the coil. If it doesn't, then the battery is not producing enough voltage.

You didn't say if you had the engine out recently, but check the ground strap from the engine to the firewall. No ground=no spark, no matter how good everything else is.
