Jeep Won't Turn Off

Just finished wiring my 69 CJ-5, 231 Odd Fire w/ HEI. After starting it and letting it warm up I turned it off and to my suprise nothing happened. I was thinking that the wire from the ignition switch that goes to the HEI distributor labeled bat. would cause the engine to shut off. I checked this wire with a volt meter and I get 12V with key on and OV with it off.

Questions:
1. Should this wire going to the distributor cause the engine to shut off when key in off position and 0V present?
2. Does a diagram exist for the ignition switch so I can double check my connections? ( I did search and checked tech section)
3. Anybody got any other suggestions/ideas of what I did wrong?

 

what Patrick said
feedback from alternator
to check, with engine running, turn switch off
if still running, unplug alternator
if engine dies, feedback problem

 

Patrick - I was wondering about the alternator wiring also. I have a GM alternator. It has a plug at the top with a red and white wire coming out of it I ran the red wire to the Battery post where there is also a wire coming directly from the battery to it. The white wire is hooked to a wire coming from the new fuse panel and labeled 'alternator excitor'.

Does anybody know what is supposed to cause the engine to shut off? Is it the wire coming from the ignition switch that is 12v switched and goes to the HEI or something else?

 

jpflat2a- That's actually how I turned it off. I unplugged the wire at the top of the alternator (red and white wire).

 

Sparky- The wire going to the HEI is 12v when switch in 'run' position and Ov when in 'off' position. Is this what is supposed to the motor off?

 

if it's an internal reg Delco (3 wire), then you have to install the jumper wire (exciter) between the bat lug terminal and terminal #2 on the back of the alt

 

sounds like your alt wiring is not quite right

 

jpflat2a- It is an internal reg Delco (3 wire). Plug @ top of alternator has red and white wire coming from plug.

Red wire - #2 goes to Bat. post on back of alternator.
White wire - #1 goes to fuse panel labeled alternator excitor

 

Does anybody know the answer to the question what causes the engine to shut off? Is the switched 12v going to the HEI module?

 

hook the keyed wire from the alternator to the acc. post instead of the ignition on post.

If you have the Alt. light hooked up you need a diode in the wire from the alt. to the light to prevent feedback.

 

This is hopw my system was hooked up when I still had the original wiring harness. When I went to the EZ-wire I no longer needed it.

 

Put a high power diode in the exciter line. The feed back is coming back through it. What is happening is that you are energizing the ignition circuit through that line. You can get them cheap at Rack Shack and solder it inline.

 

Need to speak to Strider380...R)

Just wanted to close this thread out. The diode did the trick. Thanks to all who helped.
