Default Re: new points, no spark...

I lubed the cam lobe for the points in the distributor... No brush on the points.

Voltage at run is about 10 volts... I noticed that the coil, new by the way, has two wires running to the positive. One of which is the braided white "resistance" wire. The concern I have is that both the resistance wire and the constant 12v wire are connected to the same power source coming through the firewall. It seems that one or the other is redundant and should be connected to something else, perhaps the 12v wire should be connected to the start position while the resistance wire should be connected to the run position?

This thing has run just fine up until about a month ago. Everything went to shit when I changed those nasty little points and the condensor.

The new distributor should be here on Wednesday, I know the one in the engine now aint good, all sorts of horizontal play. It just seems like there is something more at work here

As I don't have a Scout, I wouldn't want to suggest how the wireing should be connected. I am sure someone will have that info for you. Will the new distributor have the points setup or the pertronics conversion?

Whether Scout or pickall, there's no difference when it comes to wiring for a points distributor. From what you describe, there is a potential issue here. The braided wire is a resistor wire and provides your switched on power supply. The other wire connected to the coil + should be originating at the starter solenoid. This wire provides a full voltage bypass during starter crank only. Once the engine is running, the braided wire takes over, and the bypass wire is dead. If this is not the way you have it wired now, you need to make the necessary correction. If the wire intended to be the start crank bypass is originating from the key switch instead, then it is bypassing the resistor wire at all times, which defeats the purpose of the resistor wire.

Scoutboy, I had a feeling that wiring was incorrect. Gotta love what po's do to these things....I found speaker wire connecting the oil pressure gauge to the sender unit!
To clarify, the braided wire and the wire from starter solenoid will connect to the same positive terminal on the coil. The braided wire originates from ignition, run or on position, and the other wire should run from starter solenoid. Is there a position on the solenoid I should look for?

Bill, going with the points for now, as I couldnt afford both the new distributor and the pertronix, but that is an upgrade I plan on making in the near future!!

Speaker wire is neither the best nor the worst choice for that application. If these two examples represent the worst of the po virus on your rig, you're light years ahead of most folks in that regard. While you're performing inspections, now is the time to take a good, hard look at that resistor wire from end to end. If the length has been modified or if the insulation has been damaged, you should probably ditch it in favor of a standard 14ga wire interrupted by a porcelain ballast resistor with an approximate 1.8 ohm value. Since you plan on installing a points eliminating module at some point, this would be a logical progression to that end anyway. Stepping up to a ignitor II or iii if available is well worth the minor difference in price. When that time comes, you won't need a ballasted feed to the coil, so the funky resistor wire would have to go then anyway. With a ballast resistor in place, you'd simply need to bypass it by joining the wire ends together minus the resistor block. If some emergency arose which required you to revert back to points, the wire ends could be easily separated and re-attached to their former positions on the resistor block.

Default Re: new points, no spark...

All right scoutboy, got the ballast resistor, gonna install it now an just bypass the old resistance wire. Is there a specific spot on the starter solenoid I should tie in the 12 v wire to the coil? Or should I use my tester to determine the hot spot with key in start position?

Bill, got the message on dist install. Thanks for taking the time to type it all up! Should be here tomorrow afternoon. Can't wait!!!

I believe its the 'r' terminal. 's' should be for energizing the solenoid from the key switch.

I puzzled it out!! I'm glad to have another little bit fixed and correct. Now I just need the distributor!! Ignition system will then be completely new.

New distributor installed!! Went in without a hitch, than you mr bennett for your suggestions. Starts better than ever and I haven't seen the tach so steady, ever!
Scoutboy, thank you for your help as well!! The wiring corrections have deffinately helped with my starting issues!

Next up is the braking system!!
