Twoods196 Posted March 8, 2008 Report Share Posted March 8, 2008 I got a set of fender custom shop texas special pickups and the middle bridge doesnt work...I posted about this awhile back but never got anywhere with it. Did some reading tonight and it says te middle pickup is reverse polarity...does it still hook up the same? or am I suppose to cross the wires Quote Link to comment Share on other sites More sharing options...
Dauntless Posted March 8, 2008 Report Share Posted March 8, 2008 If the switch you are useing is a standard Fender switch http://www.fender.com/support/diagrams/pdf...0134600DPg2.pdf If you are useing a Stewart-Macdonald switch http://www.stewmac.com/shop/Electronics,_p...91.html#details If it's not a switch problem, check all your solder joints and make sure wires aren't coming in contact with each other causeing it to ground or short. If it looks sloppy, clean it up and you'll probably find the problem. Quote Link to comment Share on other sites More sharing options...
Twoods196 Posted March 8, 2008 Author Report Share Posted March 8, 2008 No, it looks good all wires neat and everything but the middle one just doesnt work. I can hook the mexican one back up and it works fine. So was just wondering about the reverse polarity. Quote Link to comment Share on other sites More sharing options...
John Abbett Posted March 9, 2008 Report Share Posted March 9, 2008 If you've hooked another pickup to the connections and the other pickup works, you have a problem with the pickup or the connection of the pickup to the switch. The pickup will "Work" if you swich the wires, it doesn't matter which polarity you use to just get it to work. It's just a big coil. If it's backwards, you lose the hum cancelling properties of having turned on two coils with reverse polarity. Take your meter and check the coil, it should have some resistance. If it's either open or shorted, you have a problem. You could also take the wires and put them on the contacts of another working pickup (This puts it in parallel), you can touch something metal to the pole points to tell if it's working, just turn your amp down a little, it makes a pretty big pop sound which might not good for speakers if it's loud. If you don't get sound out of either at that point, you have a short. You know when you are testing this stuff out, you can wire the pickup right to your input jack to test the thing out. It bypasses the switch and the pots. Polarity doesn't matter for the test. -John Quote Link to comment Share on other sites More sharing options...

Geo Posted March 10, 2008 Report Share Posted March 10, 2008 The pickup will "Work" if you swich the wires, it doesn't matter which polarity you use to just get it to work. It's just a big coil. If it's backwards, you lose the hum cancelling properties of having turned on two coils with reverse polarity. I think you'll have an out-of-phase sound. To cancel hum without cancelling signal, you need opposite MAGNETIC polarity between the coils and the coils must be wired electrically out of phase (start-to-start, finish-to-finish). If you reverse one of these factors (in this case, the wiring) you will have a sum sound that sounds out of phase and does not cancel hum. That's my understanding, could be wrong.

Twoods196 Posted March 11, 2008 Author Report Share Posted March 11, 2008 Found the problem. The wire that goes from the solder points to where it starts to spool is broken. Can only find one side of it...so guess its a RMA. Quote Link to comment Share on other sites More sharing options...
