7. The easiest way to remove the battery from under its spring-clip is to
first place a small flat blade screwdriver in the notch in front of the battery, and
lift the front edge of the battery above the lip of the battery holder.
Next, place another small flat-blade screwdriver in the notch in back
of the battery, and push the battery forward, out and over the front lip of the
battery holder.
8. Make sure that the "+" side of the new battery is facing up, and then
slide the new battery into place under the spring-clip.
9. Replace the Engine cover, place the hood prop back into its holder,
close the top panel and tighten the captive screws on each side of the console.
Replacing the Output Protection
Module
1. See Figure A-1. First, perform steps 1 - 5 in the battery replacement
procedure above to access the Output Protection Module under the Engine
cover.
2. Locate the Output Protection Module as shown. Gently remove the
cable assembly plug from its connector on the top edge of the Module. Mark
the cable, if necessary, to remember which connector it attaches to.
3. The easiest way to remove the Output Protection Module is to hold it
with your left hand, then use your right hand to pull the front spring tab toward
you to release the front of the Module.
Tip the front of the Output Protection Module slightly to the left so it
clears the front spring tab.
Next, use your right hand to push the rear spring tab away from you to
release the rear of the Output Protection Module. Tip the Module to the left
and lift it out.
4. To install the new Output Protection Module, orient it so that the gold-
edge contacts face down, and so the component side of the Module faces to the
right.
5. With the Output Protection Module tipped the left, place the gold-edge
contacts firmly down into the slot at connector J13. Now tip the Module to the
right and snap it into place. Check to be sure that the Module is held properly
behind both the front and rear spring tabs.
