6.1.5 F ASTCHECKr Diagnostic Tester
(DEC 3+)
The FASTCHECKr diagnostic tester simulates engine
operation to identify faults in the controller and engine
circuitry. Use the FASTCHECKr when troubleshooting
startup problems or to test and troubleshoot the
controller when it is removed from the generator set.
Perform tests without starting the generator set.
FASTCHECKr functions are listed below; refer to
Figure 6-7 to identify LEDs and switches.

6.1.6 Float/Equalize Battery Charger Kit
with Alarm Option (DEC 3+)
The float/equalize battery charger with alarm option
provides battery charging to the engine starting
battery(ies) and connects to the controller for fault
detection. Battery chargers for 12- or 24-volt models are
available as a generator set accessory.
See Figure 6-8. See Section 6.2, Accessory and Prime
