Replacing the starter was simple matter of spinning the bolts... But
hooking up the electrical cable was not... The electrical post on the
SkyTec is about 4" forward of the stock location... The aluminum
starter cable (original) is as rigid as a piece of pipe... There is no
movement possible... So I got a piece of 2-0 copper cable and and big
lugs... Borrowed a battery cable crimper from the auto parts store and
custom built an extension to the starter cable...

Why isn't it a problem connecting dissimilar metals Cu-Al in a high-current
application like that?

I know of course that Al starter cables are used in lots of aviation
applications, and eventually they have to connect to some kind of copper at the
starter, but why isn't there a corrosion problem?
