Sun LV Battery — Starter Tester

I finally was able to rebuild this unique tester. It's a Sun VAT, but was specially made for the US Military. Unlike traditional automotive VAT testers, this one doesn't have a carbon pile resistor, but rather a group of HUGE wire wound resistors called a "Load Bank".

This little baby was meant to diagnose 6,12,18, and 24 volt ignition systems. Basically anything from a Jeep to an M60 Patton tank was diagnosed with one of these Military grade VAT testers. If you tried to do that with a conventional VAT it would turn to cinders within a few seconds.

The exterior was great, just the internals were a mess (mice ate through a lot of wires, resistors and capacitors).
