Back in the 60s, my father took our car to a local mechanic who did not have a ring finger. Herb (my dad) explained that the mechanic most likely lost the finger working on a car with hot wires which heated his ring.
The image of a red-hot ring on my finger stayed with me. As a result, I ALWAYS take the battery out of the circuit AND take my ring (watch too) off when tooling around the car. I have been looking to install a quick battery disconnect and wondered why they are all on the negative side of the battery. On the EE (theory) side of the equation, this is not as logical as the positive (not to open a can of worms) but on the practical side, I did not know why. Dug around for a while until I found the reason buried in a very weird board about ATVs. The writer's referenced "Wrench Slip Arc" as why you disconnect the negative. For no other reason than you want to wrench the POSITIVE first so if you slip the wrench you are not then holding a filament. To me, this was an epiphany and decided to share this matter of safety. Please forgive me if this topic has been explored to exhaustion in your respective spheres. CTC911CTC |
