Old, but new, test equipment.
I've worked with these VAT-40s for years.  I really only needed a way to test alternator output with a good load and the VAT-40 fits the bill.  I could have gotten a cheaper load tester but the Sun VAT has character and capacity, both.  And, new overlays for the gauges and the main panel are available that give a new look to this machine.  This one was built in the mid 70's and still works.  No pics yet of the new look.
