2.1 Appearance and condition of components
2.2 Initial Operation
The following procedure involves starting and stopping the engine using the
Engine Control Module (ECM). For the purpose of this procedure, it is assumed
that the engine is properly connected to the 12 Volt ignition battery and that the
natural gas (or propane vapor) fuel has been installed, pressurized and tested
for leaks. Refer to the CE3X2/CE9X2 Enclosure’s Installation manual (p/n 031-
099-C0) for wiring diagrams and information pertaining to the battery
connections.
All engine operation will be controlled by the ECM. Verify that any switches
on the engine/generator (or engine/alternator) are switched to the center
(neutral) position and that all circuit breakers on the generator are switched ON
(if applicable).
NOTE: Refer to the ECM Operator's Manual (p/n 744-862-C0) for
complete ECM operating instructions.
2.2.1 Ignition Battery Test Procedure
1. Connect a DVM (set for DC Volts) to the IGN BATT terminals. Connect
the Red (+) lead of the DVM to the (+) terminal and the Black lead
(-) of the DVM to the (-) terminal.
2. The DVM should indicate 12 VDC (+ 2 V , - 0 VDC). If this reading is
lower than specified, recharge the batteries to 13.8 VDC before
proceeding.
WARNING: Do not use batteries (AGM or Gell Electrolyte)
that read below 9.0 VDC, as the battery may be
discharged below a safe point and could cause
gassing during recharge.
