Battery ground

Postby diamondback0320 » Sat May 06, 2017 12:07 pm

Is it really necessary to ground from battery to the engine..Reason for asking is that's where I'm grounded now..Getting new cables made & not really a lot of places to bolt a ground on the aircraft motor..Besides that every mount is a rubber mount..So seems to me a more solid place to ground would be somewhere more solid like the rigging or the aluminum stringers as I have a aluminum hull..Idk just a thought

Your best bet is to run a ground from the battery to the starter housing. If you don't have a good ground to the motor it will leave you stranded at some point very soon. This is a common problem I see all the time.

Ground motor to rigging, from rigging to hull with double 00 cable you won't have any problems

Given level of importance, this is the best place to start. Doing so may save undo strain on the starter and grounds the block all in one motion. Running a jumper from there to the rigging/engine stand will get that as well.

On a boat, you can not have to many grounds. Redundancy can and will save immeasurable grief over time.

My current setup has two from the battery ground: the first goes to the starter/block, the second to the rigging near the battery. There is additionally one from the starter/block to the engine stand. This one is by rights redundant, and ought not be needed, but serves as a back up and cheap insurance. I've had no electrical hiccups in eight years now, so have become partial to this arrangement.
