JM 1 Wiring Help

Dear All

The JM1 pick guard and tone knobs come pre-loaded and soldered but has anyone got any idea how to connect it all together?

Thanks

This may help.

And, from the wiring guides section, this image should put the linked post in context.

Peter - any chance of a slightly better photo of the control plate? I can probably draw something up for you - just need to know where you're starting from. Mainly want to see where the light purple and the white from the 4 wires connect to.
Cheers.

Brendan, from Peter's photo it looks like his is set up as (I think):

single black wire: tone 2 pot casing --> bridge ground
blue wire: jack ground lug --> pot casing grounds --> switch ground lug
purple wire: volume pot right lug --> switch centre lug (switch output)
white wire: tone 2 pot left lug --> switch left outer lug (bridge tone)
grey wire: tone 1 pot left lug --> switch left inner (both) lugs (middle & neck tone)
Caps link the middle lugs of the tone pots to their casing, and another white wire connects the middle lug of the volume pot to the tip lug on the jack.
For the pickup connections on the switch, bridge hot = right inner lug, middle hot = right middle lug, neck hot = right outer lug, with the grounds connected to the switch ground lug.
(left and right are relative to Peter's photo)

But, it seems like the factory wiring for the JM's has changed over time, and the colour coding could vary between different batches of kits so a diagram may not always match up completely.

Gents. Thanks for replies but need more help because I know jack about wiring guitars. I have attached some slightly better photos. Murphy's law states that photos of wiring looms will never be in focus. Here are some notes that might help.

Yes a blue wire has come away from the input jack lug

Black wire to ground on bridge

The wire coming away from pot closest to jack is white

Wire coming away from middle pot is grey

There are two wires coming away from pot furtherest from jack blue and purple. Blue from casing (ground) and purple from left hand lug

The PUPs connect to switch as follows
Humbucker 3rd from right
Middle 2nd from right
Neck last on right

Hope this helps and thanks in advance

Peter, hopefully this will sort you out.

First up, the control plate…

Connect the black ground wire to your bridge/tremolo, and reconnect the blue wire to the jack's ground lug (as indicated):

For the bundle of 4 wires (grey, white, blue and purple), you have two options with how to connect them to the switch. Basically, how you want your tone controls to work. The blue wire is the ground link to the switch body, the purple wire is the switch output, and the white and grey wires are the tone connections. The 'dots' are the solder points.

Option 1:
Tone 2 = Bridge pickup, Tone 1 = Middle & Neck pickups (the grey wire needs to connect across both points). Given that the bridge pickup is a humbucker, this is probably the most useful setup.

Option 2:

Tone 2 = Middle pickup, Tone 1 = Neck pickup, Bridge pickup has no tone control. This is more a traditional Strat type setup where the bridge pup doesn't have a tone control.

A potential third option would be the same as option 1 but to not link the grey wire to the middle contact, which would give you: Tone 2 = Bridge pickup, Tone 1 = Neck pickup, and no tone control for the middle pup.

Just pick the option you want and connect the wires accordingly. If you need any more help let us know.

Weirdy, you are definitely the wiring guru!

gee coming from Lozza ! I agree Weirdy is deffo the best forum wiring guru without doubt.

Thanks guys - will get to work on a diagram. Remember - if there is a diagram that we're missing, send me some photos and I'll try and get one up - I just don't have one of each kit at home to check all the parts are the right ones.

Thanks for all your help guys. WeirdBits you the man!

Here are some photos of what appears to be the "new" wiring on the JM-1 kits. As Weirdbits noted, these colours are always subject to change, depending on what colour wires the factory has on hand at the time of production.

Attachment 9833
Attachment 9834
Attachment 9835
Attachment 9836
Attachment 9837

To match the above batch of wiring colours:

Tone 2 (yellow) = Bridge, Tone 1 (green) = Middle and Neck, Volume (blue), Ground (purple)

Attachment 9850

(there are other ways to configure the tone controls, depending on what you want)

Thanks Weirdy, "Above and Beyond" as usual.

Brendan is going to update the diagram to match the new colours and make it more straightforward for those less experience in wiring (myself included).

I recently bought JM-1 kit. i saw this thread and thought it would help me out but i'm confused my self? maybe because the wires i have are different colors? i'll attach some photos.

Hi Gibson.Fender, looks like you just need to connect the loose wires from the volume pot, tone 1 and tone 2 to the switch, as shown in the diagram above posted by Weirdbits.
So looking at your first picture, from left to right on the control plate is volume, tone 1, tone 2 and output jack.
You will have to run a common earth wire from the tremelo claw and solder to the casing of the volume pot.
All the other connections appear to be done

i think i posted this in the wrong thread?? but i have my answer now i'm pretty sure...

Hi Gibson.Fender, no this thread is fine to post your query.
Start a build diary as I said in the PM and let the forum enjoy your build experience.
Ask any questions you have in your build diary

Sorry for all this confusion.. i now know what goes where thankfully
but there is a black wire so is that he earth wire??

Looks like the colours have been switched around. Using Weirdy's pic substitute blue (in the pic) for green (yours), green(pic) for purple(yours), yellow(pic) for blue(yours) and purple(pic) for yellow(yours).

Hi Sean, yes looks like the black wire is the earth wire. Looks like its soldered to the back of tone pot 2 ?
The earth wire goes through a hole to tremelo cavity and there should be a little hook on the tremelo spring claw to solder this to

As Pablo has said, the wire colours are different so substitute the colours

My wires colours seem to be the same??

Yep, your wire colours are the same, but the factory has swapped around which colours are used for the various connections (compared to the image I posted). Pablo has it correct. Using the labels on the switch (image) your colours are:

Tone 1 = purple
Tone 2 = blue
Volume = green
Ground = yellow

And, the ground connection to the bridge is the black wire.

Does that mean the Tone 1 (Purple) need to be split??

What do you mean by 'split'?

The end of the purple wire just needs to be soldered across the two lugs/pads on the switch (shown as green on my image), it then acts as tone control for both the neck and middle pickups.

I'm nervous with this soldering stuff!!

Gibson.Fender have a little practice on some old components until you have the hang of how the solder melts and how much heat is needed.Take your time. Listen to Weirdbits regarding wiring he is the resident wizard.
