I spent a little time chasing down my turn signal issue and decided to finish an upgrade that had been waiting for a long time. I have had the battery tray from Low Range for a few years. The AGM battery that i had in my old rig had flanges at the bottom that didn't allow it to fit properly in the new holder. That battery was destroyed in wreck and the new rig came with a brand new battery that was too tall for the holder.
Several parts were added or reworked; battery holder, aux fuse panel, ground disconnect, battery maintainer.
The factory battery tray is bolted in, so i used the same locations, but with countersunk bolts. I used the hole dimensions from the factory tray to locate new holes in the Low Range battery holder and countersunk the holes. Countersinking the holes was necessary to keep the bottom of the holder flat. The factory tray has recessed areas to keep the hex bolts away from the battery.
My new rig doesn't have ABS, so there was an unused fuse location in the main fuse panel under the hood. I had planned for this project and had cut the ABS power wire from the old rig's harness. The wire came with the right connector and was sized for the 50 amp fuse I had also pulled. All new connectors received crimp terminals, anti-ox, and heat shrink. I added a battery ground disconnect also. A wire was run from the ground disconnect to the aux panel ground bus. My battery maintainer is wired directly to the battery terminals, before the ground disconnect. I have to leave the rig for several weeks at a time and try to keep the maintainer plugged in when I do.
The new battery has the terminals towards the front, which caused an interference issue. I had to move the positive cable to side with a post adapter. The factory cable had a fitting that allowed it fit over the side post, without modification. I just had to remove the factory terminal.
It's hard to see the fuse panel on the far right of the battery tray in this picture. I will get a better photo of the fuse panel later. The black box in front of the battery holder is the maintainer (label long since came off). The 12ga. black wire connected to the battery side of the ground disconnect goes to the maintainer. The positive side of the maintainer is connected to the positive bus of the fuse box. This may be an issue if I have a parasitic drain. The clear and blue piece sticking up behind the battery is the fuse for my cooling fan controller.
