57 kaiser willy ,cj5 won't start

[Chromeguitar]

I'm losing it , gonna cry!!
I changed the points,rotor, new coil,
I've skipped the ignition (putting in new painful harness ) and have a button to solenoid and battery to get her cranking ,,,the coil is hooked up to the battery and neg to distributer,
It turns over but no spark. I've tried testing the coil, but am not sure if I am doing it right. Any body tell me how to check coil.
Another question. Is it possible the battery is just not strong enough?
Missing the mud;.(

Your coil positive should put out 12 volts with the key on. A couple of times after a tune up I have had no starts due to a bad condenser. I have also bought bad points that were not insulated correctly.

 

[Chromeguitar]

I did get a new condenser, but I got parts at napa. And am not sure how well they match stuff up, I should have gotten oe parts maybe.?
It's odd the jeep was running then cut out and would not start again,
After it had been running fine.
I will do an ohm test right now

 

[Torxhead]

The coil should be at 1.35 ohms. You could run a jumper wire from the battery positive to coil positive to try and hotwire it. You did set the point gap right?

 

[Chromeguitar]

Thanks Torx
I will try now. I have tried going direct like this before. Is the coil grounded as the - on the coil goes to the distributer which is connected to the engine?
Wishing I was smarter!

 

[Torxhead]

On the older CJs the coil negative went to the ignition switch. How it works from there is beyond me. You might have an issue with loose connections.

 

[Chromeguitar]

I'll run though connections again. She turns over nice. But just no spark.
I got a good reading off new coil. 1.25 1.35. Hmmm. How would I test it when engine is cranking ? Would that tell me anything different?

 

[Lumpy Grits]

Your SURE, you set the point gap correctly??
The condenser should 22 mfd rating.
If the engine is crank'n strong-Your battery is good.

Thnx Lumpy G
Yeah I set the points , more than once. Triple checked,
How can I tell if I have the right condenser ?
It's not the same as the original. I guess I'll buy a original to be sure
I hate to go with electronic one. But maybe I should.

 

[Torxhead]

I have seen where a bad starter switch will prevent a points ignition from starting, but in this case, it seems to be an issue with your tune up installation.

 

[Lumpy Grits]

The base of the condenser should have it's rating marked.
Was this a 'kit' you bought at NAPA?
If so-You should be OK.
Could you have moved the dizzy while installing the points etc?
Confirm-It was run'n before the parts chg??

[Lumpy Grits]

Can you post any pictures of the open dizzy-So we can see the points etc??

[Chromeguitar]

Torx. By tune up installation do you mean points and rotor set up?
It wouldn't start before I did any rebuild stuff. I think it may be a ground issue , Would you recommend an electronic ignition (the kind you stuff in the distributer). Or not.

 

[Lumpy Grits]

Get it run'n first.
Run a POS(+) lead from the battery to the POS(+) side of the coil.
Run a GND(-)from the coil to the battery GND(-).
Now-does it start?
If it does, you have a wiring foul-up somedangwhere.
To stop the engine-Pull the POS(+)lead from the coil & battery.

Please don't connect the neg side of your coil to the bat. That goes to the distributor.

 

[Lumpy Grits]

Please don't connect the neg side of your coil to the bat. That goes to the distributor.

All neg(-), ends up at the battery.

It goes to ground, but it has to go through the points first, if you want a spark from the coil.

 

[Lumpy Grits]

Your correct-
We're looking for ign circuit/switch issues.

Try something quick and simple .... and old school. Test your coil. Run a hot wire to the coil, attach a wire to the other side but don't hook it to anything. Hook a spark plug wire directly to the coil and ground the spark plug. This works best in a relatively dark place. Touch the ground wire to ground, then pull it off, there should be a decent spark at the plug. This is what the points are doing, the points close and the circuit is grounded, the coil builds a magnetic field, the points open and the magnetic field collapses creating a huge jump in voltage (2400v if I remember correctly) and a spark jumps the air gap in the plug. If you get a good spark the coil is good, at least when it's cold.
