I believe it does matter. I defer to Fabo and the electrical gurus when I have electrical issues.
When our fusible link burnt, it happened immediately(within seconds) when we hooked up battery +ve. I spoke to Del/67dart273 on the phone and he was just as quick to diagnose the problem as it was for us to create it lol.
Bad alternator.
Yeah I was wondering if it mattered I noticed one had a copper lead the other didn't which is the one I grounded and I know my ammeter gauge was working good
