Made some nice (and quick) progress last night.
Here's how I started, viewed from the left:
...and from the right:
I removed all the wiring and used my new-to-me recip saw to cut the bulk of the body to break it free from the molten battery bucket, then removed the bucket. This is what I'm left with:
In all of this, I realized that I actually didn't need that main harness. There's only a few wires with mild-moderate burn damage and it's only on the last ~4". I can easily splice on new wire, terminals and replace the loom and it'd be 100%. Since the replacement harness I got yesterday needs splicing in the middle of it, repairing the original harness would be easier. I wish I had known it wasn't so bad so I could've saved a few bucks on that other harness. But, I wanted to have the replacement in hand for reference since I thought the original was destroyed. It was mostly just covered in melted battery bucket plastic that peeled and flaked right off. The harness that got the most damage was the power cables to the motor. I got this harness as well yesterday, so that's handled. Although, I'll probably remake it with larger gauge cables since I'll be making upgraded battery cables.
While inside the cart, I noticed this label:
I filled out the questionnaire on the company's site to get the details on it- Modded for torque? Speed? Both? Either way, this was an exciting little bonus to find.
I'll have to remove the flip-flop seat to remove the remains of the body (those two rear fender/side pieces). The only remnants of the fire damage will be that back lateral span. It'll be covered by the new body and battery bucket, so I'm not messing with it. I'll scrub it to get the stinky soot/molten plastic smell off when I spray down the cart.
