2nd Battery and Ground Connection Questions

[jslipher]

Question for your experts on wiring grounds. I recently added a 2nd battery to my Sport 200V using the Blue Seas Add-a-battery solution. The Sport 200V already had a Blue Sea red main kill switch for the single battery under the driver's helm. I mounted the new Blue Seas switch in the same spot and separated the power wire from the starter away from the house and amp power wire. With my new Amp installs I routed the grounds to the new house battery (2nd battery).

My question is: Should I re-route the grounds from the house electronics bus bar to the new house battery also? I never changed the house electronic grounds, so I assume those are still going to the original battery, which is now just my starter battery. Will this cause issues or stereo noise (too cold here still to try and test for engine noise).

How long is the ground link run between the two banks?

How long is the ground link run between the two banks?

For the amps going to the new House battery, the run is only 2ft long. The other House electronics must be going from the driver's helm back to the engine block and original battery in the v-drive locker, so I'd guess that run is 12-15ft.

A 2ft ground from the amp(s) to the house battery should not cause any noise issue.

Thank you! Do you forsee any electric problems with the other House electronics having the power wire sent to the House battery, but having the ground wire sent to the Starter battery?
