<VV> alternator ground wire?

[shortle]

My 1988 Volvo 240 Wagon alternator is mounted with rubber bushings which means the alternator does not touch metal. Therefore there is a separate ground cable for it. The Corvair alternator mounts to metal meaning there is no need for a separate ground wire for the alternator. But make sure ALL grounds are good and even more than is needed. The original bean counters could never think that way but for a few extra bucks I want less troubles.
