STEP 5: Remove the wiring harness from this battery and install it on
the replacement battery. You may want to check for
continuity of the red lead, as it has a fuse. If there is no
continuity, replace the fuse with a 3.5 amp in-line fuse
(Accom P/N 2000-0023). Connect the black wire (gnd) to the
black battery terminal and the red wire (+6V) to the red
battery terminal.
STEP 6: Set the replacement battery in the chassis (terminals toward
the left side of the chassis) and connect the battery harness to
Motherboard connector J18.
STEP 7: Reinstall the battery bracket, securing it with the four M3
nuts. Again, you may need to hold the power harness out of
the way to tighten the right-hand nuts.
STEP 8: Reinstall the Switcher board into the chassis. Use the
inserter/extractor tool to seat the circuit board connectors
completely into the Motherboard connectors.
STEP 9: Power up the Signal Chassis. To test the replacement battery
and related control circuit, recall an Engineering, Personality,
Effect, or User file from a floppy disk into memory. (See the
Disk menu description earlier in this section for more
information.) Power cycle the Signal Chassis and verify that
the file(s) just recalled are still present in memory. If so, the
unit is ready for use.
