Actually got it out and cleaned it yesterday

 

Hopes that helps. I believe four wires that plug into relay then a wire running from battery to post with other wires going to the post. These pics are just to help me put the wires in the same place when I put it back on. Good luck bud

 

Very very nice. Both replies. Thanks much. :wave:

I gotta get out there with this info and take another look over and then I may not have to ask this, but my last visit with this mess I was interchanging wires off the main relay post to the battery trying for the right combination to get the starter to engage via key forward.

I see some diagrams showing a wire from that main starter relay post to the battery.

My setup is currently battery to main lug on starter, but nothing to the relay. (which I figure can't be right because that would mean that little solenoid wire would be carrying all the power to the relay).

If I run a wire from battery to main post on relay it makes it hot and engages the starter, (the way I currently have it mix matched mind you).

So, I probably just have the wiring currently mixed up, but basically, is there supposed to be a main power wire from the relay post to the battery? I figure yes and that is my issue.

Thanks again for the pics. Ya know, what would be really cool is a screenshot from when you entered the search terms to find that thread. My search skills on here blow.

 

yes, one big wire from battery to side of solenoid. one big wire from other side of solenoid to starter power.

 

Solenoid? Thought we were talking relay here? IDK...

The small battery cable (8 gauge stock) goes to the big post on the starter relay. Then, the 4 or so 10 gauge wires with fusible links go on the same post. This is the power supply for the whole jeep except for the starter.

 

Lol. Just ran that configuration. Starter engaged with key forward and wouldn't disengage. Don't fret too much, I'm going through this wiring...

On mine, the small trigger wire that goes to the starter solenoid is the green wire with a stripe (might be white, might be tan or yellow).

 

look at this

The solenoid (small wire going to the top round thing on the starter) ground and ignition wire are all marked. The large stud will have a heavy gauge wire which comes directly from the battery, plus a bunch of other wires connected to it (it serves as a power distribution point for several loads) Let me know if you have questions.

 

ya I got that already. Well, one that is my actual relay, (I have 4 spades). My concern was with quantity of wires going to where, (mainly the "bunch" of wires). Thanks though.

 

Hmpf. I have a ground wire I put on from one of the spades to the block. That can't be right, I know I read somewhere that it is self grounding. But there is a "G" marked on the relay.

Maybe that's why it continued to crank with the key off?

I think my biggest question is...
Is there a wire from the relay post to the battery, or not?

My setup is batt to starter, solenoid to relay.
No relay to batt conn.
No idea why I didn't snap pics of this thing before hand.:dunno:

 

yes, there is a wire to the large post on the relay directly to the battery. It is not self grounding. You must have a wire to a good ground. The black/white wire you have marked as reverse lights is actually the ground wire and connection point. Without the ground wire, you will turn the key and get nothing, nada, dead as a door nail at the starter.

 

Hmm, I don't have one of those on my jeep

 

Then where does the small positive battery cable go?

 

oh boy... look what I found. Was I drinking when I took these???

The second one aint so bad. I can sorta confirm what Berniebikes and the diagrams are saying. One of those reds is a winch wire so the other musta went to the relay.


Copy that on the ground Berniebikes. Tnx. Last time I had it hooked up like that, (power from batt to relay post and grnd to block), it cranked with key on and wouldn't stop cranking! Lol. Obviously something is wrong, I'm trying to work it out.

 

While you are messing with it, moving it up higher on the firewall makes it a lot easier to get to and maintain.

 

copy that

 

There is a wiring harness in the middle of the firewall going down to the trans. 6 pins. Do you have the 6 pin connector hooked up that goes to the reverse lights etc.?

 

No. No lighting wiring hooked up...

 

Ground the terminal that says ground in the pic that was posted.

 

My relay has 4 spades pic has 3. If I go to autozone.com and match mine up with that it will engage the starter and not disengage.

Putting the dash back in right now incase there's a ground or something in one of those connectors.

 

If you have one more connection you probably have this one

ignore the fuel pump ballast connection, you don't have an electric fuel pump, the 4.2 is mechanical and you will control your TBI pump by the TBI ecm

 

Okay. Now when they say To Key On 12V Source... what exactly is that? Can I plug into the relay? Fuse block? Do I have to trace wires off the ignition switch? IIRC there was 3 wires that need 12V key on for the ecm.

I tried that config in that pic a few days ago. No dice. Once I get the dash back togethor and all connections made maybe that will help.

 

Does your relay look like the one in the pic? It's it just not turning the starter over?

 

Yup. I trimmed down existing wiring, removing sensors and redundant wiring. Which is why I'm not pressing the issue too hard.

But yeah, same as last b&w pic.

Thought I saw somewhere that supposed to be 2 ign. switch wires to relay?

 

I'm sure Que will answer. He's the guru. Key on means a wire that supplies 12v when the key is in the "on position". You need a wire that supplies 12v when the key is in the "start position" not "on position" to connect to the start relay. Think about it, you only want the relay to switch voltage to the solenoid (which in turn engages and allows the starter motor to turn) when the key is in the start position. When you release the key from "start" you want the solenoid to disengage (pulling the bendix back out of the flywheel) and the starter motor to quit turning. Otherwise, assuming you wire it with "key on", your starter will engage and turn any time you turn the ignition to the "on position". get out your meter and find the right wire. Otherwise you are shooting in the dark. Forget about what you think you read somewhere. Only one wire from the ignition switch goes to the relay

 

So someone needs to hold the key forward for me while I probe

or get yourself some aligator clips and a 12v bulb, clip one to ground and the other to the wire you are testing. When the bulb lights you found the wire
