Hi, I have a no crank situation where I have done the following…

-Tested battery & starter (both good)  
-Cleaned grounds (Chassis, top of transmission & from starter)  
-Tested fuses

Best voltage reading going into the ignition switch is 8V. When I turn the key, I have about 6v going out to the starter.

I’m thinking the ignition switch might be fine & my problem lies with a another ground somewhere? Car is a 2012 Fiat 500.

Thoughts?

Also, how was the battery tested?

something is consuming power upstream of the ignition switch. look there. if there were a short to ground, the voltage would read lower than 6v (zero).
