This subject is important enough to spin it off into it's own thread.
I'm sorry to say it Richard but I don't have a background in electronics. I have however been thinking about this for quite some time.
If we are going to own and use these cars over a long period of time then we are going to have electronic failures. It is going to happen. We can pay a lot of money for replacement parts if they are still available or we can, what? Pay someone to rebuild the part in question or do it ourselves.
The price to rebuild electronics, I suspect, may be based on the price to replace the electronics. Seems like a fair price to get a working component unless you know how much electronics cost.
There are lots of stories out there about a common failure in a particular car that costs three or even four figures to fix by a professional when it can be done at home with a meter, a soldering iron and a ninety cent diode.
A new EZL goes for $1300! A common failure is heat related and the fix is the replacement of some small components inside the EZL.
Almost a no brainer.
The challenge is finding schematics for EZL's and all the other electronics that WILL give us trouble in the future. There are many variations on each component.
For all the people that are on this list no one has reported having any electronic component schematics at all.
This is a big gap in our knowledge.
One that we will all pay for sooner or later.
Regards,
Chris
