The prior owner has installed a non factory wire from connector on alternator to positive battery terminal . Why would someone do this ?
to have a direct link to charge the battery with an internal regulator.. thats how us race car guys go it and 2 gauge wire also.more is better...
In the old days many GMs were wired that way. It must have been done for a reason by an older mechanic. Personally, I'd leave it alone if it's not causing any problems. If it works, don't fix it. HTH. -Jim
