Yes a Handy man is best to use to test SCR Components,not unless you have access or can purchase a Model 275 EV1/EV100 Analyzer,with this you just unhook the system control card and use the Analyzer test card for the system your working on you can test ALL components and even the contactors with this analyzer,if you do a Ebay search for forklift analyzer you will see that they go for about $1400 new but found mine ALOT cheaper on ebay a while back. This analyzer is/was made by flight systems here in PA, i havent seen another used one go thru ebay since i purchased mine.
