DEAD UNIT/LOW BATTERY VOLTAGE:
See “SCHEMATIC - MODELS 040213 & 040234 -
GENERATOR” on page 66
for circuit details.
A unit with a completely depleted starting battery will not
be capable of powering the digital display or the remote
LED. If the generator cannot start because the battery
output power is below that needed to crank the engine,
the digital display will show
FC_1
.
NOTE
: If so equipped, the CMA will
simultaneously signal the remote LED to blink in
a sequence of one and display “Low Battery
Voltage” on the Statstation
™
screen as well.
The causes for either of these problems may be a failed
battery, a parasitic drain on the battery or a failed trickle
charger. The circuit functions and test/repair procedures
for these three conditions are outlined below.
The trickle charge circuit is a float charger type and is
designed to maintain the voltage of the battery. When
UTILITY voltage is present and the unit is switched to the
AUTO
or
OFF
position, the trickle charge circuit in the
CMA will maintain the voltage of a fully charged battery.
The trickle charger may take as long as three days to
fully charge a dead battery.
240VAC UTILITY is delivered from the fuses in the
transfer switch to the 2-pin connector mounted directly to
the CMA board. The CMA uses internal circuits to rectify
this UTILITY voltage to 12VDC. This is then delivered to
the (+) battery post through the 15 Amp fuse via
Pin #1,
Wire #13
.
Test 1
Check Battery:
1. Switch the SYSTEM switch to
OFF
.
2. Remove 15 Amp fuse.
3. Disconnect battery cables, (-) negative first.
4. Using the approved procedure for your battery
tester, check the battery state-of-charge.
• When charging battery, set charger at 2 Amps
until full charge is indicated.
If battery replacement is required:
• The replacement battery must be the same
12VDC, AGM type, 33 Amp-Hour Battery.
5. Connect the battery cables, (+) positive first.
6. Reinstall the 15 Amp fuse.
7. Set SYSTEM switch to
AUTO.
Push and hold
MANUAL OVER-RIDE
to start unit.
Test 2
Check DC Amperage at Battery:
Follow the recommendations of your meter’s instruction
manual.
1. Install DC Amp meter between Positive (+) battery
terminal and Positive (+) battery cable
(Wire #13)
.
NOTE
: Depending on the state of charge of a
battery, a slight (+) current flow indicates that the
charging system is working.
If a (+) current flow is detected:
• The trickle charge system is functioning.
2. Reconnect the positive (+) battery cable.
3. Reset the fault code detection system
“Resetting The Fault Code Detection System” on
page 20)
.
4. Set SYSTEM switch to
AUTO
push and hold
MANUAL OVER-RIDE
to start unit.
If a (-) negative or zero current flow is detected:
• Proceed to test 3.
CAUTION
: Do not exceed the 2 Amp charge rate.
CAUTION
: Do not replace with liquid electrolyte
(lead-acid) type battery.
