Stereo e-stim troubleshooting.
Posted: Mon Mar 04, 2024 5:47 am
I was in danger of hijacking the Restim thread, so I've opened a new one here.
@diglet, @Kelvinator and @47dahc: I checked all the possible connections with the continuity check feature on my multimeter. The only notable reading came from the input connections, ie, the black and red channels going into the transformers. This is either expected behavior, or I have really screwed something up.
Any thoughts?
Thanks.

I don't see anything obvious. Could the hexnuts securing the purple and green outputs somehow cause a short? I had a mishap while drilling the holes in the faceplates, so those two sockets are close enough that the hexnuts are in contact. I used sockets that don't have any gap in the plastic housing to avoid making contact with the aluminum case.

The only other thing I can think of is that I crammed the components in to a case that's too small (you can see my initial screwholes for an arrangement of the resistors that didn't fit). Could the housing of the resistors making contact cause a short? Am I just an idiot for using a metal case in the first place?

If your sockets are shorted out against the case, then yes, this will short out that channel.I used sockets that don't have any gap in the plastic housing to avoid making contact with the aluminum case.
Yes. The hex nuts are metal, so if they are touching, that will cause a short.Could the hexnuts securing the purple and green outputs somehow cause a short? I had a mishap while drilling the holes in the faceplates, so those two sockets are close enough that the hexnuts are in contact.
No. The housings are nothing more than heat sinks. The heatsinks have no effect on the resistor value unless somehow the leads are in contact with them.Could the housing of the resistors making contact cause a short?
I think the best thing you could do is get a multimeter that has continuity check on it. Read all your connections out to the case, to the heat sinks, and between each other. A quick YT search should provide countless results on how to use a multimeter.
