Today I was working on a piece of machinery with a small part of the circuitry being 24 VAC. Every time I would try to use the machine controller to pull in the necessary contactor, it would not pull it in. I removed the contactor and connected it directly to the transformer. Pulled in just fine. When the relay that controls the contactor would energize, my 24 VAC would drop from 24 VAC to 0 VAC. Eventually tracked the problem down to a slow blow fuse that did not blow completely. Turned into a 33K ohm resistor. So I could see voltage just fine, but it wouldn't carry any current.
Has anyone else seen something like this? Been doing this a long time and that was a new one on me.
Yes I know, you always check the fuses first, but when I had voltage, one makes assumptions. Wasted 2 hours today on it. Lesson learned I guess.
