L2KE Electronics Problem

Postby ampig » Wed Oct 29, 2014 9:25 am

Hey all. I see a lot of familiar names from BABP here. Let me make my first post a whiney request for help. The two position humbucking/single coil switchon my 81 doesn't seem to do anything. Anyone have a similar experience and/or suggestion on what may be wrong?

`

Not doing much ? Like, it IS doing a little something [other
than making a click-click sound] ? IOW is the bass stuck in
dual humbucker mode or in OMFG mode ? Did you tap on
the poles with ferrous object ? and if so what resulted ?

Alternatively, I bleeb there's a sticky thread here with the
`81-82 schematic, and you can desolder every thing from
the switch, test the switch itself and, if the switch is OK,
redo all the solder ... and prolly replace the cap cuz 35yrs
is pretty old for a cap. You can also leave out the cap and
convert to later ser-par switching if you prefer. The latter
might require a different switch .... not sure. Myselves, I
have both and would rather retain the OMFG mode. YMMV.

All in all this is pretty lite duty work, so if you don't care
to do it yourself, it won't cost all that much at a shop.

EDIT: A typical fail mode for an old cap is a partial, often
near-total short to ground, so if you've got humbucking in
normal mode but very little signal in OMFG mode, then I'd
strongly suspect the cap is ailing. IIRC, if the cap is bad,
you can just snip one leg of it, and the switch will still
give you humbucker and SC modes, but SC without the
bass boost.

New basses are red. Used basses are black.

Here's what I got:
With the switch towards the bridge all 4 sets of coils are equal volume
Switch towards the neck rear set of coils on each pickup are a little hotter. Front set of coils are still in the circuit on both pickups but are thinner sounding
There may be slight difference in sound between the two switch settings, but I'm expecting something pretty noticeable like on my old L1K
