REFERENCE INFORMATION
These tests check the strength of the batteries during
engine cranking. lf you don't have STE/lCE-R, skip
this step, but remember that you haven’t tested the
batteries under load.
STARTER NEG. CABLE VOLTAGE DROP
STE/ICE-R TEST 69
1. Start Test 69, starter negative cable voltage
drop.
2. Displayed reading is in volts. The cable voltage
drop should be less than 0.25 volts maximum.

BATTERY CIRCUIT
BATTERY INTERNAL RESISTANCE
STE/ICE-R TEST 73
1. Disconnect wire 54A at injection pump to
prevent stating.
2. Disconnect glowplug controller and fan
solenoid.
3. Start Test 73, battery internal resistance.
4. Waif for the GO massage. Crank the engine.
5. Result is displayed in milliohms. Battery
resistance should be 25 milliohms max.
BATTERY RESISTANCE CHANGE
STE/lCE-R TEST 75
1. Disconnect wire 54A at injection pump to
prevent starting.
2. Disconnect glowplug controller and fan
solenoid.
3. Start Test 75, battery resistance change.
4. Wait for the GO message. Crank the engine.
5. Result is displayed in milliohms/second.
Battery resistance change should be
50 milliohms/second max.
