Vent caps are to be tight and level on both batteries. Place a
damp cloth over any vent caps on each battery, making certain

WARNING
– BATTERIES PRODUCE EXPLOSIVE GASES.
NOTE: consult automobile owner’s manual and follow all instructions.
SHIELD EYES AND FACE FROM BATTERIES AT ALL TIMES. BE SURE
VENT CAPS ARE TIGHT AND LEVEL. PLACE DAMP CLOTH OVER ANY
VENT CAPS ON BOTH BATTERIES. HANDLE CLOTH CAREFULLY –
DO NOT ALLOW CLOTH TO COME IN CONTACT WITH EYES, SKIN OR
CLOTHING. BE SURE VEHICLES DO NOT TOUCH AND BOTH ELECTRI-
CAL SYSTEMS ARE OFF AND THE SAME VOLTAGE.
Be careful to avoid moving fan blades.
Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually
has larger diameter than NEGATIVE (NEG, N, -) post.
Determine which post of battery is grounded (connected) to the chassis. If
negative post is grounded, connect clamps in order shown in top diagram
and as described for connecting clamps with a grounded negative post.
If positive post is grounded, connect clamps in order shown in bottom
diagram and as described for connecting clamps with a grounded positive
post.
NOTE:
Regardless of the polarity of the system, always connect the
short end of the wires, indicated by the arrow on the smart indica-
tor system, to the dead battery. This will allow the voltage indicator
to work properly.
