Ever since adding the dual batteries, the way they were secured in the engine bay has really bothered me. Basically, the only thing holding them back from sliding around and taking out the drive belts and fan is one of the bolts that secures the air-bag sensor on the driver's side inner fender (located on the side of the OEM battery platform). Bolted to that is part of the chinsy little metal strap that I used to relocate the radiator overflow bottle. The battery tray was then held onto that strap with another little piece of that same metal strap bolted through one of the holes in the bottom of the tray. Ever since, it's always rattled a little bit and could easily be moved around on that single pivot point by hand and rocked down towards the drive belts and fan.
Not ideal:
One bolt! AYFKM!!:
So, I decided to work on my welding skills and build something a little more sturdy to secure the tray in place. There are two bolts that secure the air-bag sensor that should be enough to hold everything securely. I may add a couple more down lower if I feel like it's still not quite secure enough and I can get a drill in there.
I started out with a 3/16" piece of steel bar recycled from my bent cam gear holder tool I made. It was a frankenstein bit of fabrication and ultimately I wasn't happy with how I only had one bracket basically holding the tray down (funny enough I was fine with the booger welds).
Welding is hard!! -Barbie probably:
So, I came up with a better design that has dual angle brackets made from 1/8" steel. This was connected together in the middle and at the end on the top for extra security. At the end are some M10x1.5 nuts welded to the underside:
Deez nuts are big:
The next part made me really nervous as I had to weld a piece of 1/8" steel bar to the battery tray in order to secure it to the new brackets. I was afraid I would end up ruining this really nice batter tray (from Rough Stuff) and blowing my weld through the side of if. Fortunately, the only issue I had was catching some of the paint on fire that I didn't grind off:
Yep, I suck at welding but I think it'll hold:
Once everything was back in place and bolted down it was about 22 to 23 times more secure (my math could be off there, but I'm no mathamagician).
All in all, pretty happy with how it turned out considering I'm using a HF 125amp flux core welder. So far, the angry pixies and I seem to be getting along.
