Never but they farmed out so much stuff it is incredible. Has to be a few hundred different models of stuff I have seen. Amazed that sleuth machine did not sell and the coil tester did.
The Sir-con is what we tested gauges with. Handy tool at the dealer. My boss go it when he worked at the Pontiac store. We had a Vat 40 as well. I think they are the finest carbon pile charging system testers ever built.
