Garrard Zero 100

Well, I have recently acquired a Garrard Zero 100, and all works except the wiring. I would like to know if anyone has previously disassembled one of these tone arms or has tips on doing it. I'm quite good with electronics and disassembly, but additional information never hurts.

That cartridge is a Realistic Shure put on there for testing, since it's confirmed good. It came with a Pickering, unknown model number, but investigation will happen, with a Pickering D100 stylus.

The fact that the thing works puts you waaaay ahead of the game. Before playing with a re-wire, be certain that it is not the muting switch or contacts in the head giving trouble.
 
yeah, I did mine once. Getting the wires routed around the bearing at the headshell end is a pain. If they aren't just so, it will bind and cause you all manner of trouble. Honestly, I'd try cleaning the fingers underneath before getting into the wiring. It needs something extremely flexible to have much chance of working. I used some 40-#46 litz wire (40 strands of #46 wire) intended for winding radio coils. It did OK, but more flexible and smaller would have been easier.
 
I should have been more descriptive, I was including those contacts with the wiring. I will definitely clean them, they do look quite nasty, and I'll bet they're great resistors. I don't see a muting switch in this though, the wires from the cartridge go directly from the cartridge to the RCA output jacks. I was honestly surprised how good the rubber, including the idler wheel was.
 
I restored one of these a couple of years ago after finding it abandoned on me street corner. I left the wiring alone but the arms underneath had frozen up with old grease so the auto load function did not work. It took a long time to find the offending pivot so it may be a good idea to clean off all the old grease and re-lube to stop any issue in the future, assuming it is has not been done already. They are a nice looking tt though and a real piece of exquisite engineering.
 
Guess you don't know the old saying.

If it ain't broke................................ This is a Garrard. Just leave things alone.
 
The early production Garrard Zero 100 had problems with the wiring breaking at the pivoting tonearm head. Repair is possible but tricky. At the time, Garrard introduced a redesigned harness/head and wiring assembly. It was easier to replace the whole thing than to cut short the existing wiring, reposition it and resolder, and more reliable too. Of course with Garrard gone for about 25 years, the part is no longer available.
 
Oooh, I know someone who might have the part.
