I'll just scope it down to yesterday. I intentionally short-circuited a 36v battery to see if the battery is still functional or not because my multimeter is out of power. I did this intentionally or otherwise usually in 12v environment to either test out quickly if the wire is connected, or when i accidentally shorted the terminal. The spark are weak on 12v so no big deal with 36v right?
It's the brightest spark i've ever witnessed in a semi-controlled environment, second to welding spark, and it leave a blind spot in my vision for about 10 second. The terminal melted a bit, and the wire bit that touched the terminal disintegrated. Also almost start a house fire with that.
Note to self: wait until you get your equipment in working condition before you work with electric.
So ,you would short a car battery to see if it's working??
Only on an old car to test if the stray wire connected to positive or not, or on a disconnected battery to see if the battery is strong enough for bench testing something, or to demonstrate what happen if you touch two jumper cable together while it connected to the battery.
