Second position signal drop

[jpfx88]

So I'm wiring up a HSS strat and I got it all together but in the second position that includes the bridge and middle, the signal drops. In each individual selection they are fine but when together it drops. Any idea as to why that's happening?

Yes. Your pickups are wired out of phase. Reverse the wires on one of the pickups. If it's only the second position that is lower volume, your bridge pickup is out of phase. If the problem is in the 2nd and 4th position, the middle pickup is out of phase.

From your description it has to be the bridge pickup which is good because it is easier and more foolproof to reverse the leads- assuming that it has 4 conductor wiring. (If not I think that the simplest solution is to add a second single conductor cable connected to the coil lead normally going to ground rather than trying to replace the existing cable with a multiconductor one. For the added cable(s) you only need one end connected to ground and it is much easier to do that in the control compartment. YMMV)
