Use the following procedure to charge the battery:
- Turn OFF the charger.
- Ensure that all of the 12V battery terminal connections are clean and tight.
- Connect the charger positive lead to the battery positive terminal on the battery.
- Connect the negative charger lead to a solid engine ground in the engine compartment. If the negative battery cable is disconnected, connect directly to the battery.
- Turn ON the charger and set to the highest setting for normal charging.
- Inspect the battery every half hour after starting the battery charger.
- Charge the battery until the taper-rate charger indicates that the battery is fully charged.
- Estimate the battery temperature by feeling the side of the battery. If it feels hot to the touch or its temperature is over 45°C (125°F), discontinue charging and allow the battery to cool before resuming charging.
- After charging, test the 12V battery. Refer to Battery Inspection/Test .
NOTE:
Do not connect the negative charger lead to the housings of other vehicle electrical accessories or equipment. The action of the battery charger may damage such equipment.
