LP wiring issue - what am i missing?

Post by Mattallica »

It's right in front of me and i can't figure it out.

I'm not getting any output from the bridge pickup when just the bridge pickup is selected. I'm using the continuity setting on the multimeter to try figure out what's happening. I'm taking the reading across the hot output of each pickup to the hot of the output jack:

Neck position - Just the neck pickup beeps (as it should)

Middle position - The neck and bridge pickups both beep (as they should)

Bridge position - no beep

what is going on? there aren't any loose connections. So either something is broken or earthing somewhere.

Please help

Is the pickup selector switch shorting?

Also, I fixed an Epiphone LP for a guy at work. One of the pots had turned and was shorting against the screening paint. Killed the output of that pickup.

Sod it, i'll just buy another switch. I uninstalled a phase push/pull because i thought the pot was the problem. What a waste of time

before you buy another switch, have you tried desoldering and resoldering the points on the switch?

The amount of times I tried to get my goldtop going last year ... holy fuck. A pot was dead.

It'll be something real dumb like backwards wires. Honestly if I were you I'd have an early night and have at it again tomorrow. Fresh eyes help.
