fd alt swap wiring question

i just put an fd alt on my 84 gsl-se and was wondering if i can run the positive cable directly from the alt to the batt. or do i still have to go to the connection that is on the dynamic chamber first?

It won't cause a problem unlike the inutitive thought that it would....I've had the TII 80 amp alternator wired both ways in two different cars and never had a problem with either set-up, just with Cadillacs pulling out in front of me in the rain..lol...

I ran a larger cable directly to the battery. If you got a larger alt with more amps, I think its a good idea to upgrade the power cables.

looks to be just a mounting tab. I took it off and grounded the mounting hole off the plenum when I polished it.
