Battery shunt resistance?
I've been getting some wacky readings from my power meter. I'm wondering if the shunt is bad and wanted to see if it can be checked by measuring resistance? It is a 75mv shunt. Thanks!

75 MV means that the rated current there is .075 volt drop across it.
I=E/R so R-E/I the resistance is 0.075/rated amprage.. Or if it is a 200 amp shunt, then .075/200.. You will read dead short on your average Multi-Meter. takes very special hardware to read that close to zero.
