Yea, i think the folks here ought bench test at home.

Adv-Auto store bench testers look pretty overkill, like the battery charger blast-proof box looks overkill. Didn't figure they were only a show-n-tell

Unfortunately, Auto Zone, Advanced Auto Parts, Oriely's Auto parts, average employee doesn't last 3 months. If an employee makes it 6 months, they are likely a store manager. I buy allot of auto parts and do my very best to stay out of those 3 store chains. I have a single local NAPA store. 2 grouchy old guys and 1 in his 30's working toward being grouchy as well. The 3 have 75 years of parts store experience. Yes they can test starters and alternators, batteries, will install air filters and wiper blades for walk in customers. They know how to operate a memory saver when changing batteries, can program key fobs, check TPMS sensors for battery life. A real parts store! Not many left out there.

Yes those GM starters are easy enough to test at home. Youtube has plenty of info or you could buy a lone wolf 6000 as well.

I do not know why more people do not buy their parts online. Most places like Advance Auto give you a 10%-15% discount when you place an order online. Then you get the added advantage of making sure you order your own parts correctly and have no one else to blame but yourself. I always shop around for the best prices on parts whether it be ebay, rockauto or local parts places
