I bought a fender Rhodes off Craigslist recently the volume seemed fine but now I realize that the upper register is ridiculously quiet. I have tested the pickups through tapping a screwdriver against them most work fine with the exception of 3 but I don't think that would make the significant drop in volume I hear. Anyways if you can help me out it would be greatly appreciated.
Here are some pics

Additional details
Whoever had this before me tried to modify it into a stage model which explains some things..
The tines are all in decent shape and I recently replaced all the grommets and springs and most felt.

Also if anyone has a good understanding of the wiring aspect I would love to hear from you
Thanks so much,
Adam

Thanks for the pics - it looks like someone removed the high end wiring... the component on the right I believe was used to reduce hammer noise in the highest registers on 88s, where hammer noise was louder than the tone itself.  There seems to be more than that missing however, if you can take a look at google images of Fender Rhodes 88 keys or something like that, you can find live examples of what the wiring should look like.  Here are a couple:

Thanks for those pictures I have tried to rewire my Rhodes to look like the others but to little success mostly because I'm not sure of the attachment points of each wire,

Is there any place I can find in depth wiring schematics?

Is your wiring diagram correct?  It appears to show the top end of pickups 73,74, and 75 connected to ground, and the bottom end of pickups 1 and 2 connected to ground.  Should the top end of 73,74, and 75 go to the middle solder post?
