1.Disconnect the 7P connector from the mode control
motor.
Connect battery power to the No. 1 terminal, andground the No. 7 terminal. To avoid damaging the
mode control motor, do not reverse power andgrouno.
MODE CONTROL MOTOR
Using a jumper wire. connect the No. 7 terminalindividually to the No, 2,3, 4,5 and 6 terminals in
that order. Each time the connection is made. the
mode control motor should run smoothly and stop.
lf the mode control motor does not run when jump-
ing the first terminal, jump that terminal again afterjumping the other terminals. The mode control
motor is OK it it runs when jumping the first termi-
nal again.
lf the mode control motor does not run in step 3,remove it, then check the mode control linkage and
doors for smooth movement. lf they move smoothly,
reDlace the mode control motor.

Troubleshooting
Tips and Precautions
Bef ore Troubleshootin g
. Check applicable fuses in the appropriate fuse/relay
box.
. Check the battery for damage, state of charge, and
clean. and tight connections.
. Check the alternator belt tension.
CAUTION:
. Do not quick-charge a battery unless the battery
ground cable has been disconnected, otherwise you
will damage the alternator diodes.
. Do not attempt to crank thc engins wilh the battery
ground cable loosely connected or you will severely
damage the wiring.
Handling Connestors
. Make sure the connectors are clean and have no loose
wire terminals,
. N4ake sure multiple cavity connectors are packed with
grease (except water-tight connectors).
. All connectors have push-down release type locks.
Some connectors have a clip on their side used to
attach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its mount bracket.
LOCKINGPAWL ONOTHERHALF OFPulltodisengage
LOCKING TAB
CONNECTORBRACKET
Never try to disconnect connectors by pulling on
their wires; pull on the connector halves instead.
Alwavs reinstall olastic covers.
Before connecting connectors, make sure the termi-
nals are in place and not bent.
. Check for loose retainers and rubber seals.
RETAINER
The backs of some connectors are oacked with
grease. Add grease if necessary. lf the grease is con
taminated. reolace it.

Battery
Test
@M. Battery fluid (eleqtrolyte) contains sulturic acid. lt may couse sevore burns if it gets on your skin or in your eyes. Wearprotective clothing and a fac6 shield.- lf elestrolyte gets on your skin o. clothos, rinse it otf with wator imm€diately.- lf €leqtrolyte gets in your eyes. tlush it out by splashing water in your syes for at least 15 minutes; call a physicianimmediately.
. A battery gives off hydrogon gas. lf ignited, the hydrogen will €xplode and could crack the battery case and splatt€racid on you. Kgop sparks. flamss, and cigarettes away from the batt€ry,. Overcharging will raise the tomperatute of the electrolyte. This may torcs electrolyto to spray out of the battEry vents,Follow the charger manutacturer's instructions, and charge the battery at a proper ral€,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. lf you don't have one of tnese comput-erized testers, follow this conventional test procedure:
To get accurate results, the temperature ofthe electrolyte must be between 70.F (21.c) and loo"F (38"c).
23-50
lf the case is cracked or the terminals are roose.
replace the batterv.
Check Indicator EYE Color
lf the indicator shows low electrolyte, add distilled
water if possible.
EYE Indicates OK
Test Load Capacity (#1)
. Apply 300 amp load for 15 seconds to remove surfacecharge.. Allow 15 seconds recovery period.. Apply test load (see Test Load Chart).. Record voltage at the end of 15 seconos.
Voltage stays above 9.6
volts; battery is OK.
