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!

I doubt if the shunt itself is bad. More likely the Heavy Duty connections need attention.
If the main shunt would open up then the MV meter movement would most likely pulverize with all of the DC CURRENT going thru it...
This is why I like the HALL EFFECT Senor measure as the DC cable you are wanting to measure just simplify passes through the cent of the coil.
These Hall effect Dc current samplers were readily available a few years ago at a good price from a China company called SURE ELECTRONICS but that all changed for some reason... You could buy a complete kit with digital meter for around $35 calibrated for 75A or a 100A.. Unfortunately for me I only bought one back then haha...
The Hall Effect Sensors made by Honeywell were ideal for my apps where you just route the large cable you want to measure thru the device. Nothing to short out and touch ground etc... I need to find some more available sources for these type of sensors in 75A to 100A ratings.
