Test Method 5
Test coolant temperature faults using a 5 kOhm, 10-
turn, 3-watt potentiometer (part no. X-6136-36), 47 ohm
1/2-watt resistor, and 22 kOhm 1/2-watt resistor using
the illustration shown in Figure 8-58. Before starting the
generator set, turn
counterclockwise. While the generator set is running,
turn the potentiometer clockwise until the unit shuts
down.

1.1 kOhm 1/2-watt resistor, using the illustration shown
in Figure 8-59.

Test Method 7
This procedure allows testing for overspeed on
DD/MTU-powered models with MDEC or ADEC engine
controls and equipped with a Decision-Makerr 550 or
6000 controller. Use the following procedure to unlock
fully Menu 20—Factory Setup and perform the overspeed
test. Before using this test method, upgrade the
application software to version 2.47 or higher if not
already installed.
1. Go to Menu 20—Factory Setup
2. Arrow down to the FINAL ASSEMBLY CLOCK NO.

4. Use the controller keypad to enter the clock number
previously recorded and press ENTER.
5. Arrow down to TEST OVERSPEED SHUTDOWN?
6. Press the YES key and press ENTER.
7. After testing is complete, lock Menu 20 using the
following steps.
