Melted brake line6279 viewsThis shows the damage under the hood, after removing the charger and upper battery.
At the back of the 2 lower rear batteries, you can see 2 brake lines. One black, one white.
Guess which one melted...
At the back right, is where the melted line melted other tubes and wires.
Note that the brake line did NOT touch either of the rear battery posts!

Melted corner2979 viewsThis is a better view of the melted mess in the corner.
I've moved the tilt switch and relay out of the way.
The burning brake line melted both water drain tubes, and damaged the battery cable.

Actual cause of the fire3553 viewsHere is where I found the cause of the fire.
This battery cable was rubbing against the hold down bar, wore through it's insulation and shorted to the bar.
This is a problem because this Sparrow had the Pack Negative tied to the frame/12v ground.
The power flowed through the front famework (which appears to be isolated from the rear), then through the brake line to the back framework, which is tied to pack negative through the controller.
