ground cable has been disconnected. otherwise
you will damage the alternator diod€s.
a Do not attempt to crank the engine with the bat-
tery ground cable loosely connected or you willse-
verely damage the wiring.

oinched under them.
a When using electrical test equipment. follow the
manulacturer's instructions and those described in
this manual.
a lI possible, insert the probe of the tester {rom the wire
side {except waterproot connector).
a Seat grommets in their grooves properly.
a Use a probe with a tapered tip.
