Terminal 61 is used for the generator

indicator lamp. When the ignition is

On
the excitation voltage is applied to it and

the generator voltage when the engine is

running.

However, a terminal is required for some

systems (e.g. exterior lamp indicator) which

D
is exactly at ground potential (low level),

when the engine is not running with the

ignition
On

D
is exactly at least 10.5 V (high level),

when the voltage at terminal 61

exceeds a particular voltage or the

engine speed exceeds a particular

threshold (480 rpm).

Terminal 61e is used for this (engine running

recognition/speed threshold value).

Terminal 61e is produced in instrument

cluster (A1) in accordance with the sketched

circuit diagram:
An electronic system is ...via terminal 15

Terminal 61 and the speed signal are used as input signals which

reach the instrument cluster via the CAN data bus.

If a particular speed or a particular voltage threshold at terminal 61 is

exceeded, the transistor switches off and terminal 61e goes to high

level (terminal 61 and the speed signal are interlinked to terminal 61e

via an OR function. Also refer to table.)

The maximum current at terminal 61e is approx. 2 mA at high level

and approx. 350 mA at low level. The switching delay is

0.5 seconds in each case.

Exterior lamp indicator lamp and charge indicator lamp

The input signal of terminal 61 and the speed signal are used for

engine running recognition. Depending on these input signals the

exterior lamp failure indicator lamp (A1e14) or the generator charge

indicator lamp (A1e5) is actuated (refer to table).

The instrument cluster also passes on the status of terminal 61e as a

CAN message. The information is consequently available to all bus

participants.

On models 163 and 168 terminal 61e is only made available as a

CAN message. There is no discrete terminal 61e line.

ON-VEHICLE TESTING
WIRING CONTINUITY
1. Connect voltmeter between generator B+ terminal and ground. Voltmeter should indicate battery voltage.
If battery voltage is not indicated, check battery and check wiring between generator and battery for
corrosion, loose terminals, etc.
2. Turn ignition on and ensure instrument cluster charge indicator light (battery symbol) comes on. If light
does not come on, check wiring between generator and warning light, including indicator bulb.
GENERATOR OUTPUT
1. Ensure connections at battery and generator are clean and tight. Ensure generator, engine and body are
properly grounded. Ensure generator drive belt is properly adjusted and in good condition.
2. Connect load tester/ammeter as per tester manufacturer's instructions. Connect voltmeter leads to battery
terminals. See Fig. 9
. Start engine and run at 2200 RPM for V6 or 2500 RPM for V8. Adjust load tester
to obtain maximum generator output. DO NOT allow voltage to drop to less than 12.7 volts.
3. Maximum generator output should be within a few amps of generator rated output stamped on generator.
If output is not within a few amps of generator rated output, check generator diodes. See DIODE TEST
.
Replace
generator as necessary.
