Re: Jump Starting?
Interesting subject. Growing up on a farm we always had a low or dead battery on something. We had 6V, 12V and 24V systems and had our share of explosions with battery acid and battery parts flying. This does happen and getting covered with battery acid is not good. I am gun shy using an unmatched voltage as a jumper source. I have done it many times with no problems but it's not worth the pain when it goes wrong. When you put a 12v battery across a half dead or dead 6v battery you have two batterys bucking each other. The 12v battery will over power the 6v battery and you will have current flow through the 6v battery which will get the hydrogen gass warmed up and the hydrogen fumes start to form a cloud around the battery. This sets you up for a nice big explosion if you get a spark from a generator brush or a loose jumper cable when you crank the old girl over.
