Need some review on my wiring schematic

[jmoreau002]

I new here and I believe this is my first post. Im trying to restore an ole 55 CJ5 . It was a rust bucket when I picked it up and many of the ancillary components were trashed or missing out right. I've begun to collect all the components and plan out the wiring. Attached is a spreadsheet that I compiled for myself.

Im stuck on a few circuits and am having some trouble following some of the old schematics in the Haynes manual. Specifically:

1. The externally mounted starter solenoid has 2 small terminals. I know one of them is connected to key witch START terminal to open the current to the starter, but where does the other go?
2. Does my planned Dummy Light wiring appear correct?
3. The key switch itself has 4 positions: Key in. Left to ACC, Key in to OFF, Key in Right to IGN, and spring return START. Likewise on the back of the switch, I have BATT, IGN, ACC, START. Are my current connections correct on here?
4. Anything else that you see, please let me know.

Keep in mind that I have not begun to wire lights and accessories yet. Im just concerned about my progress so far...the engine electrical and gauges.

Thanks guys.

1. The second post is for the ACC on. You dont really need it. It is mostly used as a post to supply power to auxiliary systems that need 12v in the on position. If you have nothing to hook up there you can not worry about it.

The rest I dont know I cant open your file

Thanks. Attached is image rather than a .xlsx file. Maybe this one will work

 

[ThisGuyUKnow]

looks pretty good to me but I dont have a wiring diagram to compare to. I dont see anything that would keep that from working.

 

[jmoreau002]

Thanks. Anyone else have any insight/opinion?

The starter solenoid has 2 small wires. As you stated one goes to the "start" terminal of the key switch. The other gets 12 volts whenever the ignition is on. This is wired to the same place where the positive end of the coil is wired.

The dummy light is getting 12 volts from the green wire going to the ignition switch. That brown wire needs to go to ground, not the alternator. Do you also want to add a switch?

looks good so far you will however need to ground the open pin on the starter relay using a ground wire to the chassis or a neutral starter safety switch on the tranny also I have attached a link i found to some wiring diagrams to some willys and early cjs to compare with January | 2013 | eWillys | Page 19

The brown wire for the indicator light coming off the alternator is grounded when the alternator is not charging and provides +12V when it is charging. This wire goes to one side of the lamp. The other side of the lamp is hooked up to +12V battery power when the key is on in IGN. When the alternator is not charging, the lamp gets the +12V from the battery and ground from the alternator, so the lamp comes on. Once the alternator starts charging the lamp now has +12V on both terminals, so it goes out.

As far as the open terminal on the solenoid, gert says to ground it and thisguyuknow says it supplies 12v for accessories, and busadave says it goes to the positive terminal on the ignition coil .

Now Im confused.

 

[BusaDave9]

Okay, there is a connection on the alternator to power an alternator light to indicate when the alternator has failed. It sounds like that's what you are doing.

Next the starter solenoid.

I think Thisguyuknow is in agreement with me. This wire needs to have power only when the ignition is on. ThisGuyUKnow says accessories. I say the positive terminal of the coil. Same difference.

As long as the starter solenoid is like the one above it should be wired as I stated earlier. This solenoid is grounded with the mounting screws.

Some solenoids have a separate grounding post in the back but that type of solenoid is mounted different than the above pic.

Sorry if I said anything misleading. I dont have a jeep as old as you but in my jeep I the ACC on, or the wire that carries 12v when you turn the key from off to run, leaves the fuse panel and splits off to the Ign coil pos and the alternator and that post on the solenoid. All these are the same electrical point essentially because they get the 12v from the same source.

That post on your solenoid serves no purpose for the function of the solenoid Is what I meant. It soley serves as a post to pass the ACC on to systems that need them. If the ACC on wire does not split off for the IGN and the Alt then this post would serve as a place the connect those systems to your acc(keyed on) source.

SO yes I am in agreement with Busa. By looking at your diagram you have the ACC on(Run, key on,run, whatever you want to call it) wired to the Ign Coil positive as well as Teeing off to the Alternator. Since you dont have any auxiliary systems that Need an ACC feed it is not absolutely necessary to run ACC feed to that post. However if you wish do do so just simply draw it from the same wire you have running to the IGN coil pos.

my apologies if i confused you, I looked at my schematic again and the 14B LT BLUE 16 goes from the starter relay to the neutral starter safety switch for automatics and has a jumper in the connector to bypass it for manual trannys it then turns into wire 14A LIGHT BLUE 16 which goes to the ignition switch. It has been awhile since I wired mine, I am the one who is confused I thought that was the stud that I grounded so that my solenoid would activate the starter circuit. When I rewired my Jeep I used the Painless 10110 jeep wire harness using mostly the painless manual and referencing the factory manual.
