Long story short, I recently picked up a 2001 cherokee xj, and was doing the big 3 upgrade, battery positive to alternator positive, battery negative to chassis and engine to chassis.
I've seen a lot of guys, rather than add an additional ground to the engine block, they just grounded the alternator case directly. I picked up a new 117 amp alternator from napa along with a new battery, but did not see a dedicated lug, or area that I could ground the case to.
The issue I'm having is that I have a 500 watt RMS amp, which really shouldn't be too hard on the electrical system, but when the bass hits, it does dim the lights. I've checked and doublechecked, the grounds are good. I used a die grinder to make sure that they were totally ground down to bare shiny metal, so I'm kind of at a loss as to why the lights are continuing to dim.
One note, this is at idle. So RPM are around 700. I'm assuming that alternator output is less than 117 in this situation, could that be the entire problem?
