Wait a minute, you're saying I disconnect the battery on an
alternator equipped car (and that includes virtually ALL new
cars) as well as many lbc's and the
diode/alternator/radio/computers/cellphone/shaver/etc. are
toast? I know the battery has been disconnected several
times on my American van and everything seems fine.
Can you clarify? Inquiring minds and all
