Starting assistance.

Can't speak with any authority on jumper cables, except that as a Canadian I've been damned glad to own a couple sets. The US pattern Jeeps and M-series vehicles I'm familiar with, have a big double prong receptible somewhere handy. A select few vehicles would carry a jeezly heavy double-ended rubber cable to 'slave' the dead vehicle. I've seen pictures of slave cables on M113s in Vietnam, so the technique was well established in the mid 60's. Civilians still have to rely on less robust cables with springy hand clips to connect positive to positive, negative to negative.
