Don't take the incoming power for granted..
I find in cases like this using my fluke 115 on min/max set to minimum voltage put into a specific point in a circuit will help you figure out if a power supply lost power when this happens. I recently acquired a fluke 376fc and it has been even more helpful with logging features in the meter that can be viewed on your smart phone in a graph showing voltages etc over whatever time frame in whatever interval you want. So you could see if a power supply looses power completely, for a split second if it just dips a little. I also have a set of double ended banana plug test leads with interchangeable types of clips to put on the end to be able to leave my meters clipped on a circuit easily. If you've never seen them fluke and knock off also make a test lead end that Is a hook that slips over a wire, then the base when twisted drives a tiny needle through the insulation so you can test almost any wire anywhere without having to be at a terminal or stripping it out.
Is this an older tac 50 (t4) or is this a tac 50-04?
