Default New points.coil... no spark anyhelp ?

Hi guys, Sorry I havnt posted in awhile. been busy with the new job and working on my truck. So up to this point got new brakes all away around, New lines, new MC, the whole nine yards,running off the gas tank, Have the wiring almost done.. Few weeks ago with a help from one the great guys at the Ford car club, I got my truck running pretty good, How ever the points went out afew days after getting it running, So I ordered a new set of points. also new 6vlot coil, and plug wires.condenser.... I put everything on, Got the points gaped at the right place. I go to turn the motor over... No spark what so ever.. So I took a screw driver and just touched a part of the points and got spark.. but not when I open the points. Just not when the motor is turning over... Any ideals guys ??

P.S heres a short video..

Try it with the old condenser, new these days doesn't necessarily mean good!

If you ground the points and get spark...that means the points aint closing ??
To much gap ?
Bad grounding to points ?

If you have spark at the points, it may be the rotor.

Dono50 has a point about condenser quality. This capacitor is very important to the function of the system. It provides split second field collapse in the coil which keeps the points from arcing and burning plus it makes the inducted high tension voltage reaction last just a little longer for a stronger spark at the plug gap. If it leaks the charge or doesn't build a charge at all then the high tension spark will be weak and the points will burn up.

If your old points were burned up then the old condenser is likely leaky or non functional. You need to make certain that your new breaker points are functioning well and that the circuit is is being opened and closed as it should. The terminal side of the points can not be grounded when the points are open or they won't break the circuit like they should. Your new coil and your cap & rotor could even be suspect if all else is in good condition. Some products are better than others so it's a good idea to purchase what folks in the know recommend. There are a lot of ignition system threads on this forum if you do a search.

I've found new stock type condensors to be dodgy so I now use a Bosch GH208-C on my crab dizzy. I just have to grind a bit off the end of the mount to clear the cap when mounted and I bend the condensor up a "gnats". The original application was for 70s Nissan 180B through to skyline and 74-78 Honda Accord and Civic.

If the condensor is shorted you have the different problem that the points act as they dont open.
If you get spark poking around the points are not closing.
If you suspect the condensor take it out and run without it to see if it fires up.

I'm not too familiar with the old H 6 cylinder engines but most Fords used some form of Holley Load-O-Matic distributor. You may have a problem with the wire connections internal to the distributor. Insulators can crack and wire terminals can break. You may have a problem of that nature.
