[Healeys] Boosting positive ground

[Bob Spidell]

Ross,

Batteries are the same, the ground is only determined by the cabling 
from the battery to the chassis (ground) and the wiring harness 
("source").  Think of a 12V battery as two 6V batteries connected 
internally (6V batteries have 3-2V cells, 12V batteries have 6-2V cells).

Connect the negative (small) terminal of the booster battery to the 
negative terminal on the 6V that is wired to the harness (presumably 
through the cable to the starter solenoid).  Then, connect the the 
positive (large) terminal of the booster battery to a suitable ground on 
the chassis--or the positive terminal of the 6V that is grounded--and 
boost away.
