A DVM will NOT catch a short voltage drop. The update rate of the DVM is too slow and it averages the voltage. To see a glitch like this you'd need an Oscope.

Hi Mastertech,
Nice to have a ''master'' in here.
Yes I know about digital voltmeters needing scan times and not picking up a proper reading if the DC is not steady.
I hate digital voltmeters.
I still have some good old reliable VTVM as well as ordinary analog voltmeters.
Please read the last paragraph in red in post #15.

I'm a Certified Master Automotive Tech, hence the nickname.
I was pointing out to anyone reading this thread to understand a DVM isn't the proper tool to find these voltage drops.
I might bring home my DSO (Digital Storage Oscope) and do some testing and post the results here. I need to find out if the program I use will allow a me to post a capture here so others can see it.
