I assume you are working on the 83 CJ-7, inline 6 stated in your bio...
*I did the TR upgrade on my Jeep this weekend and I can't get it to work. I have the 258, and I did the cap and rotor and got a coil from a newer F-150(from a junkyard).
The E-core coil I presume... You didn't tell me what coil you got from the donor...
*The problem is I don't have any spark at the coil. So here are my questions..*
*1) is there anyway to check to see if the coil is working with the a volt-meter? I checked with the ohm meter and it gave me rsistance through the coil, but that means nothing to me*
There is no way to tell for POSITIVE that a coil is going to work, but what I do is check the primary side (low voltage) for 0.45 Ohms resistance.
If you have somewhere in that neighborhood, the coil should work.
You may also want to check the connector. I've seen lots of "Piece Of Sh*t Coils" that turned out to be the connector...
*2) I only have one red wire coming into the coil, and I can't find your diagram anywere to see where the other hot wire comes from I wired the old coil back in to see if it was the new coil but no spark on the old one either*
Sounds like more than a coil problem...
Did you do any work on the wiring by any chance, or unplug any of the module or distributor while you were doing the upgrade?
Have you checked the coil wire it's self?
*I guess I just need it troubleshooted. No need to tie up the board you can email me directly at
"Tieing up the board" is how a lot of people learn to trouble shoot problems...
You really didn't give me enough information to go with here...
Did you use the Cap adaptor, Distributor cap, & Rotor from a '82 Ford pickup?
If you don't use the correct rotor, the ignition isn't going to fire correctly.
Did you get the rotor installed correctly?
Are you getting ground to the module?
(Black wire coming from module if you want to splice in a proper ground)
Have you Checked and cleaned the connectors to the coil, the module and the distributor?
You should check for...
With the starter cable unhooked from the solenoid (leave battery cable hooked up..)
Turn the key to the 'Start' position, and check for 12 volts at the 'I' terminal on the starter solenoid (small terminal, one of two.)
With the key in the 'Start' position, check for voltage at the positive side of the coil, and the white wire of the module.
Let the key go back to 'Run'.
Check to see if you find voltage (between 8 and 12) at the positive side of the coil.
With the key in the 'Run' position, see if you have voltage at the Red wire at the module.
Get back to me with the results...
See if this is the diagram you need...
This is for a '78-'79, but the basics are the same...
So many cats, so few recipes...
