Jump Starting - Ford 1999 Mustang Owner's Manual

Roadside emergencies
4. Make the final connection of the negative (-)
cable to an exposed metal part of the stalled
vehicle's engine, away from the battery and the
carburetor/fuel injection system.
The preferred locations of an exposed metal part (to
ground the circuit) are the alternator mounting
brackets or an engine lifting eye. Do not use fuel
lines, engine rocker covers or the intake manifold as
grounding points.
Do not connect the end of the second cable
to the negative (-) terminal of the battery to
be jumped. A spark may cause an explosion of the
gases that surround the battery.
5. Be sure that the cables are clear of fan blades,
belts and other moving parts of both engines.

Jump starting

1. Start the engine of the booster vehicle and run
the engine at moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run
both engines for an additional three minutes before
disconnecting the jumper cables.
