No, doesn't make any sense at all.
To be honest, your whole approach to troubleshooting doesn't make any sense either.
Reading this entire thread just pickles my mind now.
Your initial problem reported in your first post, does not include any logical troubleshooting steps relative to error code (-1418).
You found a 'wire defect' for 1AE board - which seemed plausible and possibly related to the error code (-1418).
Since then you are replacing things (just like here in the UK is swapping prime ministers) for the sakes of swapping things and not troubleshooting the problem and now other problems have been introduced too.
When was the last time both 9ZA and encoder battery assemblies replaced?
When was the last time the full system was re-initialized and a backup reloaded?
How many more wire defects could you have introduced with all the in and out of the boards?
If it's now working, leave it the hell alone and look into replacing the controller and arm.
Kawasaki do boast longevity, but surely you/your boss must realise that nothing is forever....
Who knows what gives now..............
