[Healeys] Trap for the novice

[keith taylor]

Recently swapped polarity on my BNI to neg. earth  (alternator fitted) no
issues all went well

Different story on my BN2 dead short.

Problem  : -    The isolation switch was grounded on the switch terminal
took ages to find
I presume that the Lucas switch comes in various configurations The tab is
easily spotted
when you look & is part of the switch casing The reason evades me as the
tab is to light
to carry full starter motor current

If I had left the switch in the negative / earth line it would not have
been a problem but I wanted
to isolate the (pos. side) batteries
