I have a 2011 Honda CRV one morning it did not crank the dash lights flickered but it seemed that there was no power getting to the starter. At first I pulled possible blown fuses no luck, I didn’t get out of multimeter checked on a few things and whenever I would turn the key to the on ignition slot the battery would drain from 12 V down to 3 V within a matter of seconds. Upon testing possible ground issues it seems that the engine block has it ground Issue for it is showing 5 V when tested on a multimeter. If anyone has any suggestions let me know and please if you know where the engine grounds are placed that would be a big help also. Thank you guys
What is going on here

There are two main grounds, G1 & G2. G2 is a heavy gauge wire that jumpers across the the top engine mount on the right side of the engine block. For G1 just follow the two cables coming off the negative battery terminal.

BTW, Ground point G1 is you main ground / current carrier. It ties the chassis, transmission case and negative battery terminal at a single point with a heavy gauge cable. G2 at the top engine mount is a lighter gauge, about a #12 AWG wire.
