With a 10mm socket, release the terminal cover and loosen the nut that secures the positive (+) terminal
clamp to the positive (+) post on the low voltage
lead-acid battery. Release the terminal clamp from the positive (+) post and cover the terminal clamp with a dry rag.
CAUTION: Do not allow the positive (+)
terminal clamp to contact nearby components
like the low voltage lead-acid battery hold
down bracket or A/C cooling lines.
8.
Unplug the vent tube hose from the negative (-)
terminal side of the low voltage battery.
9. With a 10mm socket, loosen the nut and release the
battery hold down from the top of the low voltage
lead-acid battery by unhooking and slipping it back. If needed, tilt the battery hold down backward so it does not slip into the vehicle.10.
Carefully remove the low voltage lead-acid battery,
taking care not to damage the surrounding components.
WARNING: When lifting the lead-acid battery,
