Dual battery installation.
I now this topic has been touched on about a thousand times. But it matters more this time because it's me.
Putting dual Optimas in the Scarab tomorrow night. Make sure I have this right.
Hot from both batteries go to selector switch, one on each post from switch. Hot from alternator goes to common on switch. Ground from motor to one battery and then jumper a ground from that batter to second one.
Yes or no?

I hate to disagree... but, I have had two Formula's from the factory with dual batteries, both with ONE switch. It is true however, that if batt 1 is selected it will only charge batt 1. That is why when running, you should have the selector in "ALL" position. I only use the 1 or 2 selector if one battery is discharged to get the strongest to start the engines, then switch to the weak battery to charge it up first.
The selector switch must be one that aloows switching when charging or it can damage an alternator. Most switches made now days do allow switching.
You are good to go now!!
