originally i wired my rv12 with the batteries [earthx] behind the panel . after considering an airtight battery box i have decided to remount the batteries fwf. the engine is grounded to a firewall passthru bolt that holds the ground strip terminals for the panel and the engine compartment. the engine has a second ground from another point on the block to another bolted terminal on the firewall.
do i really need to run a cable from the neg. of the batteries to that terminal where the ground strip terminals mount or can i bolt the cable from the battery ground to the firewall by the battery and save the weight of at least 2 feet of cable?
thanks for any advice.
