1974 cj5 No Spark

ok i need some help.i have a 1974 cj5 i am not getting any spark,i have replaced the plug wires,coil,cap, rotor and points and still no spark,,am i missing anything?
thanks

Moved to proper forum.
Do you have voltage to the coil? To the ignition switch? From the ignition switch? Is the battery charged?

 

turns over fine just no spark

 

Check to see if you have power to the coil when the key is on and while you are cranking.

 

nothing

 

nothing,it just turns over!

 

could it have some thing to do with the distributor

 

OK. You need a volt meter and you need to start with the ballast resistor on the firewall. One wire comes in and one goes to the coil. Turn the key to the on position and read the voltage going into the resistor. If there is 12V, check the other side of the resistor, voltage will be lower, but there should be some. If there is no voltage to the resistor, you have a problem between the switch and the resistor. If you have voltage all the way through the resistor, you could have a bad coil, bad ground to the points plate, bad points or consenser. Is the rotor turning when cranking?

 

And don't overlook the resistor itself being at fault, if it has voltage in but nothing out.

 

74 should be a resistor wire unless someone added one of course.

 

Some history would help. Did it stop while driving? Ran when parked and how long did it set? Have you replaced any parts other than above? Have you done any simple repair or remove clean and re-install any other parts? etc etc etc.

 

neither did,,not getting power to the coil at all

 

no was running fine,,ex wife went to town on it and started cutting wires

 

no was running fine,,ex wife went to town on it and started cutting wires,replaced ,plugs ,wires,coil,dis cap,rotor,points starter ect,,,tunrs over but not getting any spark

 

Oh, there may be a few other wires that were cut, check for power at the ignition switch and even the wire that comes off of the starter and alternater.

 

Ignition switch.

Hot wire it and see if it runs.

 

Why did you start cutting wires?
A problem like this needs a systematic approach with more clear answers than you've been giving.
When someone here asks a question it's because they are trying to help. Vague or unresponsive questions will not get you where you need to be

Please be more specific and forthcoming with your posts.

 

No one has mentioned the condenser... Was it changed out as well?

 

I read this as his ex wife butchered it, and he's attempting to fix what she "went to town" screwing up.

 

Your 74 jeep is not typical when it comes to some of the electrical systems. Installing a wrong part that looks physically the same can render it useless. An example is the ignition switch. When the key is turned to start position, it grounds the solenoid. Other vehicles the start position actually provides power to the solenoid. What does this mean? The solenoid for your vehicle is unique. The "I" terminal on the solenoid has two wires, one goes to the voltage regulator and the other (ignition by-pass) to the "+" terminal on the coil. There will be another wire on this same "+" terminal which is a special resistance wire going to the ignition switch. As said above, you must have power present at the "+" coil terminal when cranking.
