Well, it depends on your goals.
It's an old car. It's something he built himself, and probably
understands. It's like fixing a classic car; say, a Model A Ford. If the
Ford's engine isn't running, you can certainly fix it (they're pretty
simple, after all). There will be a learning curve if you've never
worked on one it before. But there are also lots of people who can help.
Or, you can replace it with some new modern engine. It will certainly
run better; quieter, cleaner, more reliable, etc. But, it will also be a
LOT of work. Lots of engineering changes. And it is likely to degrade
the car's value as a classic.
Replacing the old controller is a similar situation. The EV-1 is a good
controller; it's generally reliable, and is an appropriate technology
for the times. You have to figure out how to hook it up; but it's
*meant* to be fairly easy to hook up.
I have two EV-1's. I downloaded the manuals, set them up on the bench
with an old golf cart motor and a few 12v batteries, and played with the
wires and switches until that "Aha!" moment when it worked. Yes, the
manual is confuing at first. But the EVDL was a key factor -- there were
kind and generous people here that provided the guidance and hints to
help me succeed.
