lead and all the connecting
cables of the alternator must be disconnected and the welder wires place\
d as near the welding point as
possible.

rst connect booster battery
positive (+) terminal to car battery positive (+) terminal. Then con\
nect booster battery negative (-)
terminal to a stationary solid metal part on the engine at a point away \
from the battery. Do not connect
booster cable to any part of fuel system or any moving parts. Avoid touc\
