1976 CJ7 Jeep with a engine/tranny/wiring harness out of a 1988 s10 blazer 4.3l v6 with th700r4 automatic tranny and a cj7 Dana 300 transfer case with Novak adapter.
Complete wiring harness from the s10 blazer. Painted with HOT PINK Pearl paint with standard sized metallic halographic pink flakes. Painted by me -a newb. New rear, front and side three wire LED lights, New parts, new custom dash-by me And a lot of guidance from fellow jeepers and lots of prayers etc.... :p
Hi All!

A while back I installed a lokar shifter for my th40 Transmission . I then purchased the LED indicator with boot and the LED decoder box with the n/s switch and Backup light switch. (I previously replaced the entire wiring harness with EZ wiring, but it didn't include these switches.)

To make a long story- shorter, I just need to know where the GREEN wire from the Lokar N/S relay wires into and the BLACK wire too... (The instructions seen in the photo) says to put the green wire into the starter switch.. (IN English, does that mean cut the wire that is on top of the starter swtich (starter switch relay ignition wire) put in between the two wires, and then put the black wire on the other side? Or Not...
I've included some pictures...

Any help would be much appreciated!



:notworthy:

PS... Pictures of actual parts (not diagrams) help me the best!:p
 
Anybody? Hopefully this is not a stupid question... I am not the best at electrical.. :(
(I previously wired the relay (green) wire to the Starter relay (the one in the pic) to the Starter ign wire (on top of the starter relay) . I then wired the (black) wire from the relay to the other end of the Starter relay-other end of the wire.. Was this correct? I then tried to start the jeep and the Starter Relay made a lot of noise but the engine didn't crank...

Did I wire this wrong? :confused:

The way that reads (middle paragraph), I would assume you cut the wire going from the ignition switch start terminal to the starter solenoid, and connect the green and black wires to opposite ends of that cut.

Is that what you were saying you tried?

Hi Jr,
Thanks for your reply.
Yes. I cut the ignition switch wire for the ign switch start (on the relay)- (Purple TO red wire on top of the starter relay) and connected it to one end and the black wire to the other end. All I heard was quick clicking in the starter relay. I didn't hear anything from the starter motor on the engine. (Please note: My CJ7 has been sitting for just over a year without being started since I have been fixing him up)
I don't know if the battery needs to be recharged or I hooked the n/s relay up wrong.
I've included some pics. (please don't look at the painters tape. I had the wires in electrical tape but wanted to see if I could bypass the n/s switch to get the jeep started. But the same thing happened - the starter relay on the fender clicked quickly. (I am charging the battery (a borrowed battery) To see if that is the culprit.

Since I have a starter relay/solenoid on the fender (instead of on the starter like newer cars) would I connect the green wire to the (top) of the starter relay marked "S"? AND the Black one tape into the solenoid Power wire (a separate wire that attaches to the side (battery) of the starter relay/solenoid?

Thanks for your help! :eek:

May be the starter relay is wired incorrectly? But I took pics of it before I pulled the wire harness out and it appears I did it right. :confused:
 
Ok.

What I would do is disconnect the NS Switch, and re-hook up the wire together temporarily. If it turns over / tries to start, then you know everything else is right.

Now for how you have hooked up now, to be clear, you cut the wire from the relay to the solenoid? Or from the start side of the ignition to the relay?

If the first, you may be running too much power through the NS Switch? :confused: Doesn't the relay usually add power (current) tot he system? Basically from low voltage to full voltage? I would hook up the second way I mentioned. If you take the NS Switch out of the equation, and it works, then Try it my way.

Now if it still doesn't work out when NS Switch is out of the equation, normally clicking sound comes from:


  • Lack of power (charge up the battery)
  • Bad starter solenoid (Sometimes bad out of the box, but you can test it. (this looks pretty informative, in case you are not familiar...)

You can manually jump the starter, to ensure it is operating correctly. Take the positive side of jumper cables. While in park (auto tranny) connect one side red to battery, and other side red tap on power input to starter (or on the starter solenoid terminal that has big wire going to the starter). (will spark, dont get hand "too" close...)

EDIT: I noticed here:

That you have the switch wired into 2 separate wires. or actually have the wire sliced into the same wire, but that wire is still "whole" (connected to itself as well) It sounds to me, that you are to cut 1 wire in half, and hook the two wires from the NS Switch to each opposing ends of that cut wire. (all your current should be running through the switch, you picture looks like its "bypassing the switch but loosing power getting there. And the wire is the one we described. Going from the ignition switch to the starter relay. (green on this schematic)

Report back what you find. :cool:

Hi JR,

I didn't know whether the temporary painters tape would confuse people so I just reconnected the green wire and black wire to the starter relay (s terminal).. .I also phoned Lokar and the rep., said I would just connect it to the relay marked s.
But, if this is wrong I would rather not have it hooked up.
I will try your suggestion but before that, here is a picture of how I wired up the green and black wires to the starter relay/Solenoid "S" terminal. (The N/S relay is circled in Black ink, both the green and black wires for the n/s are circled in red and the Relay is circled in blue. (I cleaned and tightened all the connections then tried cranking it and same issue. -Several places on the Internet suggest my starter motor may be bad. I looked at it on the engine and it may be full of dirt/mud from the previous owner. So I plan on taking the motor off and cleaning the inside with WD40, if it won't hurt it. If that doesn't work then I will try to bench test the motor. If it comes up good, I will then try without the relay, again. ;)
 
Here is my starter motor. It only has one thick (4 gauge) cable running from the solenoid/relay side post to it.

I will be taking off the motor today to inspect if it needs to be cleaned and/or replaced.

A little history: I bought the CJ7 last year and I could tell it was taken through streams etc. (Duh, I know, its a jeep! :) ) But they never rinsed the undercarriage off after off-roading.:(

When you tried to start it, that wire was secured tightly correct?

(sorry for the dumb question... just want to be sure, not trying to insult)

THANKS to all who have replied. And sorry for the long response. I contacted Lokar and they weren't sure which backup wires went into the decoder box for the n/s switch.. But I remembered I also bought a shifter that had a n/s switch on the side, so I connected the neutral safety wires into the Ignition switch (purple wire on top of the starter solenoid on the fender) and the jeep started right up. Unfortunately since then I needed to replace my alternator and starter motor... :( I am also looking to get a new battery since mine decided to commit suicide.
THANKS AGAIN GUYS for your continued help. ooxx
