Since this is the newbie section I made this install as simple as I could. No welding, no cutting, no splicing of the stock parts.
Dual Optimas
Remove the stock battery
stock battery
Build a tray, out of aluminum angle and flat bars, to hold the 2 new batteries and raise them to clear the stock hold down mounts.
tray1
tray 2
Using the stock plastic tray as a template, make 2 studs to fit in the stock holes to keep the new tray from sliding. (or just screw it down if you want)
template
stock holes
Make a new hold down and get new hold down bolts
hold down
Use the stock hold down locations for the new hold down bolts.
The side posts on the yellow optima: negative bolted on the fender (not the one the stock battery was connected to) and the other goes to the isolator.
This leaves the top posts for adding your accessories.
The stock battery terminals connect to the top posts of the red optima.
Red optima
The short negative wire, that used to bolt to the fender, jumps to the side terminal and a new wire connects the side terminal to the stock negative bolt.
red optima (-)
The posts on the top of the red optima are near the edge of the battery so that the postive wire will reach. The positive side post on the red optima is unused. The isolator feeds the red optima at the main fuse block.
