Ohms meter going bonkers...

[Pedrobear]

Hey all, in need of some advice:

My ohms meter is going bonkers while trying to meter my coils and I'm not sure why. I do not have any shorts and understand what they are and what to look for while building. What could be the culprit of this? By bonkers I mean, jumping around from all ranges. I finally screw it down super tight to be it stable, and its +- .5ish from intended ohms. Just bought some brand new battery's, using rubbing alcohol and q tips to clean all the threads, and tried pulling the pin up some, but alas, its still jumping / crazy off readings. For now, Im using my MM / Smoketec one, but I miss the .00 reading. (For whatever reason my fluke wolnt measure down to the .00 place)

To use the MM, just + to firing pin - to threads is good ya?

Yep.

+ is the center pin
- is the threads

Hold the test leads of your multi-meter together and note the residual resistance of the leads and then subtract that from the reading you get on your atty.

The leads impart resistance upon the measurement.

A meter which is bounching around randomly indicates a short somewhere, either in your coils or 510 connector.
