Look at the schematic and refer to the comp in the schematic.
What actual audio caps did you use? Dayton what?
The speaker at full range reads 0.4 ohms while the good one is approximate 7.6 ohms. So where is the short then, it is only a few components.
And if you open one of the woofer connections, the short is still there, and the woofer measures what R?
I assume that you thought that re-capping would solve your short issue.
Follow the schem, the big inductor(L1,4.5mH) is in series with the woofer. the schem, which shows full range switch setting,
1) Full range input + terminal goes thru L1 to s1-12 & C1(50uF), s1-12 connects thru the wafer to s1-9 to the woofer +. C1 goes to full range - terminal.
woofer - goes to s2-9, thru wafer to s2-12, onto full range - term. Pretty straight forward.
So C1 is in parallel with the woofer = 12dB/oct LPF
You can use the same logic to follow the rest of the paths.
Like I said previously, good luck finding a xover on ebay. Could be years away, if ever, no guarantee. This should be easy to fix.
You have the good working xover and I assume the other speakers are fine to compare against as well.
If you know someone who can help and follow a schem, of course take that course of action if you can not figure it out.
And of course you cleaned the switch contacts,wafers with deoxit D5, which should have been done to start with.
Good luck
