Blower Switch for P-rails....?

Can anyone help me with a diagram to wire my new guitar with blower switch..

electronics are the standard wiring diagram in support (above)

2-prails, 1vol, 1 tone, 3way, 2 push pulls. (option #2)

i want the blower to be bridge normal humbucker... i tried wiring a 2dpt switch and only worked some of the time i.e. when the tone pushpull was down.

someone suggested maybe a 4dpt switch, which i have aquired but i dont have a clue how to wire it in...

Please can someone help me?
 
Re: Blower Switch for P-rails....?

This same question appeared last month. I suggested using a 4PDT switch for the blower function. It has to go in circuit between the pickup and the push-pull switches. The idea is to direct the four conductors of the bridge/Treble pickup in one of two ways. I cannot remember whether GuitarDoc did the honours and provided a diagram or not?

Think of the 4PDT on/on switch contacts as follows;

A1 A2 A3 A4
B1 B2 B3 B4
C1 C2 C3 C4

The black, white, red and green conductors from your bridge position pickup are soldered to terminals B1, B2, B3 and B4, respectively.

The continuation wires of the four conductors are soldered to terminals A1 - A4 in the same order. These connect to the push-pull mode pots in accordance with the SD schematic.

Terminals C2 and C3 are linked with a short insulated wire. Terminal C4 is grounded. Terminal C1 is the "blower" output.


OUT - B W R G
IN - B W R G
OUT - hot link link ground

i think i understand.
thanks very much, i will let you know how it goes and if i come accross any problems.

c4 is just linked to the ground anywhere?

and is C1 an additional connection to the Hot output jack tip or the only one??

Yes. The easiest option would be to run a short wire to the same point where the 4PDT switch chassis is grounded.

When I asked ArtieToo and he never got back to me, I just went to google. Solved.

C1 is the direct out.

The A line of contacts passes on to the push-pull switches. Which of these conductor wires is "hot" depends on which coil combination has been selected.
 
Re: Blower Switch for P-rails....?

so C1 is the only hot output to output jack? ive connected it as an additional cable to output and the blower does nothing.?? help?
 
Re: Blower Switch for P-rails....?

Setting the 4PDT switch to connect the B and C rows of contacts has the two coils of the bridge pickup running in series and connected directly to whatever you wish to feed the signal to.

Setting the 4PDT switch to connect the B and A rows of contacts directs the four conductor wires of the bridge pickup to the push-pull switches as if the 4PDT switch were not there. In this mode, exactly which coils of the bridge PU are operational is governed by the push-pull switches. The overall output of the bridge pickup passes to the selector switch, the volume pot and, finally, the output jack.

Where the C1 hot connection goes is up to you. Directly to the jack socket for the basic "blower" idea. Directly to the input terminal of the volume pot, if you want that in circuit.
 
Re: Blower Switch for P-rails....?

if the basic premise is this
a1 a2 a3 a4
b1 b2 b3 b4
c1 c2 c3 c4

on on
position 1 a+b
Position 2 b+c

wouldnt it be correct to say......

a1 a2 a3 a4
b1 b2 b3 b4
c1 c2 c3 c4

a1 + a2 connection to corresponding red and white connections on push pulls from pickup wire originaly in wiring diagram.
b1 + b2 connection red and white pickup wire
c1 +c2 Linked by small wire..

a3 to volume pot middle (where output jack hot wire was) a4 pickup selector switch

b3 output jack wire b4 bridge pickup hot wire

c3 + c4 linked by small wire..

would that be correct?
 
Re: Blower Switch for P-rails....?

I am going to have to stop and think this out again.

If the green conductors from both pickups are permanently grounded, that frees up terminals A4, B4 and C4 to select between the normal and "blower" outputs with no possibility of the two options converging. I shall have to draw things out properly.
 
Re: Blower Switch for P-rails....?

thank you..
the problem i had with the blower wiring with the original SD diagram, was that when one of the coils (rail- tone pulled up) was taken out of the equasion by the push pulls, it just didnt work.. i.e when pulled up the blower when switched on was dead. nothing. no complete circuit.

but as i want the blower to work only as bridge humbucker on full whack, i dont know if the wiring would be valid.

the blower has worked on a couple of guitars i have done, i even split the coil on my tele hotrails, and the blower works as humbucking or single coil if tapped.

but i want bridge humbucker regardless of pickup config, hence, the 4pdt switch when switched to blower mode completes the humbucker wiring in series as it should be regardless of the pickup selection config. but! both coils can be switched on and off with the wiring diagram i used from the SD support page..
