1st build junior JRM-1DC

[McCreed]

I also checked the wiring diagram for JR1-DC from Pitbull guitars website, I didn't understand how do I solder the wire ground to bridge?

There should be a hole drilled laterally to the treble side bridge post hole either from the pickup cavity or the control cavity.
However, the lack of this hole seems to be a regular occurrence in a number of theses style kits.

The solution is drilling the hole yourself. You'll need a long drill bit in order to get the appropriate angle without marring the edge of the cavity with the chuck. A 3mm diameter bit will be big enough to accommodate the size of the ground wire.

And you shouldn't actually need to solder the ground wire to the bridge. It just needs enough contact with the metal of the underside of the bridge to do the job. Typically splaying the wires so it sits nice and flush when tightening the bridge to the body is a good idea.

I found the hole


Do I have to touch ground wire with bridge bushing or direct with bridge?

[Simon Barden]

Just the bushing insert. When you're ready to put the bushings in, strip the end off sone wire, put the wire in through the hole leaving the bare ends poking out into the post hole, then put the bushing in so that the bare wire is trapped between it and the side of the hole. That's all that's needed. Then when you put the wiring harness in, solder the bridge ground wire to the back of a pot.

That's great. One less thing to have to fiddle with.

Hi, which of these is the ground wire?

[Simon Barden]

It doesn't matter which colour wire you use for ground, but I always use black if I can. Just be consistent and don't use red for one bit and black for another. It makes it a lot harder to check for faults.

On the output jack, you've currently got the red wire going through the hole in the ground connection tab. The other tab is the signal connection.

ok, thank you

[McCreed]

Laying everything out as sort of a "mock build" for the electronics like you've done is a good idea. Especially if all this is new to you.
It helps visualise how things fit together and "see" the flow of signal path. Think of it as water flowing through pipes starting from the pickups finishing at the output jack.

I did it! Look at this abomination of nature (never did it before!)






I have a doubt: do the wires have to touch directly the surface of the pot or can they touch just the solderin tin and stay a bit higher? I mean e.g. from bottom to top: pot -> solderin tin -> wire -> solderin tin
Maybe I heated the pots too much, is it possible that I have damaged them? I didn't try if it works yet.
