The pickups on my 73-480 model have the following ohm readings.

11.2K for the neck pickup and about 6.5K for the bridge pickup.

I always thought that the bridge pickup should have the higher reading, because higher reading equals more windings and therefore more output power. Am I wrong or is something wrong with my guitar.

My 75-360 model shows the same 5.5K reading for the bridge pickup as well as for the neck pickup. Something wrong here too ?

Swap 'em on the first guitar. Turn up your amp and put away the VOM on the second.

You guys are really technical!

I've never even measured the output on my toaster pickups.I just ordered my guitar with them because I thought they looked cool. The sound has never disappointed me.

11.2 K on the neck pickup and 6.5 K on the bridge pickup on a '73 480 sounds totally stock to me. I'm sure the idea was to make the bass pickup real bassy and the treble pickup real trebly (with some assistance from the much-discussed .0047 capacitor too). Tragically (I hope I'm not getting too heavy haha), a smaller coil + a treble-pass cap + a magnet not one bit stronger than the bass pickup one + the pickup location (=by the bridge) meant the bridge pickup was much weaker than the neck one.

Exactly right, that’s why I made another scratchplate (I keep the original) and added a small switch to bypass the capacitor when needed.
This cuts the bass a little bit and gives a stronger sound to the bridge pickup. I like it much better now.

Also, a stronger magnet will help in no small measure.

But only to a certain point, at which it becomes a negative factor. Use a big enough magnet and the strings won't vibrate at all!

No, that is right. The reason for 6.5kohms in the bridge is so it will work better with the inline capacitor. I tried swapping and all I got was midrange mud. The better thing to do is unwind the bridge pickup to @8kohms and see if you like the tone better. I did on my 1982 360-12WB checkerboard, and you can't tell it from toasters on tape.
