Re: (ET) coop parts purchasing

I have to agree, this isn't rocket science.  I would suggest that anyone 
who has trouble understanding the wiring take a course in automotive 
electrical systems at their local community college. With that knowledge 
and a few simple tools, anyone can diagnose their own problems.  It might 
take more of your time (and none of Bills), but it's not the end of the 
world.  

Maybe what we should concentrate on is getting Bill to allow us to scan 
and post the Homeowners Maintenance Manual.

Those controller boards only have a few parts on them.  Can't they be 
restuffed with new parts?  I don't recall that they were potted or 
anything. Maybe something that an individual can do for fun (and a little 
profit) is to bag up kits of parts to restuff boards.
