Shopping at my local Harbour Freight type place and I saw this. It says : for top post batteries. Attach to negative battery post. 1/4 turn disconnects battery. rated 100 amps continuous, 600 amps cranking. Includes ATM-20 amp fuse for power bypass.
I always thought you disconnected the positive battery leed? And if you wanted to bypass to supply power on "all the time equipment" why fuse link the negative side? It was about $3.00 Attached image(s)

Pos or neg doesn't matter, but I've always put them on the + side
I use this top of the line sucker in my bug. It doubles as an anti-theft device. Attached image(s)

Yep, Princess Auto. Their headquarters is about 5 min from me. I picked up a set of 1/2" extensions (18", 24", 30" & 36") I have no idea what I'm going to use them for, but I have them incase. (IMG:style_emoticons/default/biggrin.gif)

Use those cutoffs on my MGA (key type).
Helps when you can't lock the doors >>> no door handles or locks. Just keeps those morons that are just smart enough to figure out how to start the thing from stealing it (IMG:style_emoticons/default/ar15.gif) Oh yea. Positive side for me. (IMG:style_emoticons/default/smile.gif) |

Generally racer types switch the positive side. This way in the event a main power wire or powered component becomes shorted to the chassis you can kill the power.
A lot of restoration types put this type of switch on the ground just to keep accessories from draining the battery during long periods that the car doesn't get driven. Seems to me disconnecting the battery from either the + or the - would stop current flow through the battery. Kelly |
