Jaguars not passing CAN communications

[linuxboy]

Hi all,
So I made a post a while ago about only seeing the first Jaguar in the chain. I believe this is an extension of that issue, however I am not sure. I re-followed the CAN on a Budget document to the letter (last time we didn't crimp our own wires). Anyway I can get two Jaguars working on the bus (ID 1 and 2), however the third Jaguar (ID 3) cannot be enumerated. If I change its (ID 3) to ID to 2 and switch the wiring so that the Jaguar that had ID 3 becomes a drop in replacement for the one that had ID 2. This should be drop in replacement however, will not work unless it is first in line, and any Jaguars following it will not show up.
Basically I think I've isolated the problem to the Jaguars, the only problem with this theory is 5 out of 7 Jags are exhibiting this behavior, and I really doubt that I've managed to break 5 whole Jaguars. Are there any tests you guys suggest to diagnose / fix the problem?

Thanks,
Oliver
