new pickguard tone pots will not work///where to begin trouble shooting

On a standard Fender 5-way switch there are four lugs on each side.

The switch was originally designed - badly - to be a three-way, which gave bridge, middle and neck, but was not intended to enable bridge plus middle or middle plus neck.

Musicians found, however, that they could make the "wiper" contact span two lugs at once, thus giving two intermediate switching options, bridge plus middle and middle plus neck.

Fender responded by adding two extra notches to give us the switch we have today.

Now. On each bank of four contacts, one us the common or "out" lug, and the three pickups get wired to one ach of the other three "ins".

It doesn't matter which side of the switch is used.

BUT:

the contacts on one side of the switch are NOT connected at all to the contacts on the other side.

AND:

The common or "out" lugs are located at opposite ends of the sets of lugs, so one might be bottom left as you look at the switch, the other top right.

To make your tones connect you have two fundamental choices.

You can either go the original 1950s Strat way and allocate one tone to one pot, the second to another, and leave the third (usually the bridge) with no dedicated tone control at all..

Or you can allocate one tone to one pickup and the other tone pot to the other two.

If you go the first way,, just solder the "outs" to the tones to the respective "ins" on the switch and don't bother with the other side of the switch.

If you wire the tones to the bridge and neck, you'll actually get active tone controls in P1, P2 on one tone pot, P4 and P5 on the other, as the pickups connect in parallel in P2 and P4. In P3 you'll get no tone control, however.

If you wire the tomes to neck and middle, you'll have active tone controls in P2, P3, P4, and P5, but not in P1 (bridge only). In fact in P4 both tone controls will be active.

Now. If you want to allocate one tone to one pickup and the other to the other two, you'll need to use the second side of the switch.

Start by soldering a jumper diagonally across the switch linking the two common lugs.

Next decide which tone pot will serve which pickup(s).

Let's say you want one tone for the neck and middle and the second for the bridge. This works well for HSS setups because you can use one tone pot resistance and capacitor for the single coils and a different one for the humbucker, BTW.

Solder the tone pot wire for the neck and middle pickup to the lug that is "hot" when you select P5 (neck). Solder a wire "jumper" across to the next door (middle pickup) lug. Solder the second pot to the last remaining (bridge) lug.

If you want one tone pot to serve the neck only and the other to serve the middle and bridge, just move the jumper wire accordingly.

thank you for the info...im going to rewire this and see if the second times the charm...I wired bottom pot (tone) to bridge and middle pot (tone) to neck and middle and will do that again..i followed a seymour duncan strat wiring diagram no i need to check the actual switch to make sure the "hot" lugs match
 
the pups connect to the back of a 5 way lever switch
the pots to the front of the 5 way switch
there is a jumper from pup side to pot side for master volume
the pot side of the switch connects to the tone pots...neck to pot, jumper from mid to neck, and from bridge to pot

standard strat tone pot wiring...
1rst pot = master volume
2nd pot = neck and mid tone
3rd pot = bridge tone

Post some photos somewhere so people can see what you did.
 
so with that jumper going from common to common, if I test switch lug on one side (bridge pickup) and switch lug on other side (bridge tone) with lever set to bridge position, I wont get continuity?

With the jumper in place, there should be continuity between "bridge pickup" and "bridge tone" with lever set to bridge position. So if you have the jumper, and still have no continuity there is some issue with faulty switch, or mixed up connection or something. Faulty CRL switch seems unlikely, and you could test the switch after its removed from the circuit.
 
Most multimeters have a circuit test position with a buzzer or a beeper. It's usually the switch position next to the bottom of the ohms settings. If you have a circuit, it buzzes or beeps. If you don't it doesn't.

Put one probe, it doesn't matter which, on the common out and the orher on the switch lug you are trying to test, with, of course, the switch set to that position.

Alternatively put it on a low ohms setting. The reading should change from 0L meaning no load or no circuit when not connected to zero or close to zero ohms if you have a circuit.

If you use the little image button top right next to the formatting buttons it brings up a window titled Image Properties. Hit the upload tab, select your file, the click the Send it to the Server button, and they should still upload. Like this one just did.

BTW Mine was a 97 916 bought brand new in Aberdeen,, Scotland..

Upgraded with carbon fiber everything, a blueprinted engine, Marchesinis, Ohlins front and rear, JH Perfornace pipes and chip, AP Racing 6-piston brakes, and a whole lot more I've forgotten. It got totaled shipping it across the Atlantic. Someone bought what was left and its still out there somewhere in the south of England. R916KSS.
 
Sounds fun!
I remember the days when I had a BSA 650 set up for racing. I had a friend who was a racing bike mechanic who tricked up his Triumph and we would go out to the back country roads and race. We once got up to 135mph, still climbing, neck and neck, but we looked at each other and agreed that was enough...very scary. Fastest bike I've ever owned. My favorite, though, was my Harley Super Glide that I completely chopped.
 
I rode a Harley. ONCE.

A gay friend of mine in Scotland had one. Harleys are big sellers amongst the gay biker fraternity in the UK, something to do with a certain Robert Halford, I expect. Anyway.

There's Kenny, done up like Freddie Mercury meets Rob Halford on the 916, me in full racing leathers, etc. on a Sportster.

German tourist with a BMW stopped in a layby for a smoke and a look at his map hears us coming, and the WTF??? Look on his face... priceless.
 
One last thing, make sure you are using a HIGH wattage soldering iron to solder to the pot casings. You need a short, sharp, intense blast of heat. You don't want to "gently warm" the pots as this will cook the internals.

That's a very important point...one that I have been stressing for years.

That's funny. I guess when you're used to the quiet of a BMW, hearing those two bikes come up on you would be quite a shocker. My Harley would get some looks, but my BSA only had tin cans with holes for mufflers...it was LOUD! People would cover their ears when I rode up.
