Default regulator/alternator issue and grounding mod?

So my bugeye is having a charging issue, either the voltage regulator or the alternator (battery was tested bad too and replaced, 5 months out of a full 3 year replacement of course!).

My question is, does having an amp/multiple amps cause any issues if I am still using the stock grounding setup?

I'm going to have the regulator/alternator tested tonight, just want to make sure there isn't anything else I should do to prevent another failure.

I'm assuming 6+ years is a reasonable time to fail on these, but thought I'd ask those with more subaru electrical knowledge

If you are using equipment that requires a lot of current you should think about installing a alternator that has a higher current output. Six years service for an alternator is pretty good.
