Good to hear from you and that you don't have to sit in either a really hot or really cold trailer on some jobsite.
Those old solenoid testers will probably work for years although most don't carry a Cat rating today.
Thanks for using our products I have so many older versions of something we still make too.
Hey if you are in need of a new tester and I can help you out let me know I may have one.
