Alternator Upgrade

Grinder, I have to say that everyone is pointing you in the right direction. Having done some of the "other" fixes myself and running into some issues, I found myself going back to correct the age issues because the new accessories didn't behave well.
For example:
I added a stereo, amp, tach and an electric cooling fan, so I swapped to a 90A alternator, only to have my stereo shut off when I had the lights, A/C and wipers on....the connections/wires had so much resistance that the power inside the firewall would drop below 12v. So back to cleaning up the connections I went..time consuming and tedious BUT well worth it. I didn't start a fire in my car but I did have to replace a connector in the fuse block (melted)

Moral of the story...get the system working the way it was designed, THEN start the upgrades.
