If I recall, he last time I had AAA come to jump-start my vehicle,
they indicated that the Alternator was working OK, and that battery was the problem. The tool they used to perform this check looked like a battery pack ?

Is this the same type of system check they do in a shop ?
I suspect the shop used more sophisticated equipment ?

Another thought, could this be a fuse related issue, not getting proper ground?

Thoughts ?

Halogen bulbs dim over time, so I suspect it is the bulbs. I have a 2011 SUV and I just replaced my dimming bulbs with LEDs. Wow, what a difference. I have a battery and charging system checking device and all tested OK.

I hope this helps.

Are you reading 13.8 VDC or so when running?

They likely load tested the battery but I wonder if they tested the alternator output as well. a new battery can mask an alternator problem.

I would take it to Neil's Laconia Auto on south main street, Laconia. He will be able to diagnose the problem and fix it.
