Procedure
for Condemnation of Battery
1. Verification of Defective Battery by Units
a. Unit MTO/Workshop Officer, upon identifying that battery is not able to hold charges, are required to note the service life of the battery.
b. If the defective battery service life is above 2 years, verification of the battery condition is not required. The unit shall proceed to send the defective battery to the respective zonal workshop for condemnation and the zonal workshop shall issue a new battery to the unit.
c. If the battery service is within 2 years, units shall test the battery using a hydrometer, which determines the condition and acid density of the electrolyte. Refer to table below for the specific gravity readings of battery under various conditions:
|
Specific Gravity |
Battery Condition |
|
1.26 - 1.28 |
Fully Charged |
|
1.23 - 1.25 |
75 % Charged |
|
1.20 - 1.22 |
50 % Charged |
|
1.16 - 1.19 |
25 % Charged |
|
1.13 - 1.15 |
< 25 % Charged |
|
< 1.12 |
Fully Discharged |
d. If the battery electrolyte specific gravity drop to lower than 1.23, add distilled water 10-20 mm above separator plates. Charge the battery at normal ampere rate not more than 10% of the nominal battery capacity (Ah) for about 7 hours. (When charging is completed, only distilled water should be added in cell for fluid losses due to gassing and evaporation.) If the specific gravity still drops below 1.23, the battery is considered defective.
2. Verification of Defective Battery by Zonal Workshops
a. The unit is responsible to send the defective battery
to their respective zonal workshop (DSMB/GSMB) immediately for verification.
b. At the zonal workshop, batteries found to be sulphated
shall be condemned without further verification. Other defective batteries
shall be slow charged at 10% of the battery Ah capacity for about 7 hours
to verify their condition. If the batteries are confirmed to be defective,
the zonal workshop shall issue new batteries to the unit and retain the
defective batteries for disposal. If the batteries are found to be serviceable,
the batteries shall be returned to units for continual usage.
Back to top
Return of Excess Batteries
1. Units with excess/redundant batteries can return them
to GSMB with APB authorisation. The unit will raise a Malfunction Report (MR)
to R&I, 1 GSMC, stating "Return of Access Batteries, No Replacement
Required" in the job request column. The maximum number of batteries that
can be accumulated in one Malfunction Report is 20 X batteries.

Re-spraying of Tactical
`B’ Vehicle
1. The system manager has established the criteria for selecting
tactical `B’ vehicles for complete re-spray. The criteria is as follows:
a. If the vehicle’s paint work has faded badly (evenly)
or has multi-tones (due to series of touch-up jobs in the past), check that:
i. the vehicle has been in active service for more
than 5 years, and
ii. the last complete re-spray done is not less
than 4 year before the vehicle can be selected for re-painting.
b. If cost of touch-up painting after CM / accident
repair exceeds $ 1500, the vehicle should go for complete re-spray.

Frequent Weak/Flat
Battery for Mazda Mini-Bus
1. In the preliminary feasibility study by the system manager
on the air-con installation in the Mazda mini-bus, the existing alternator (55A)
was found to be sufficient for the total power requirement.
2. However, problems surfaced when the driver "misused"
the air-con (e.g. switching on the air-con while waiting in the vehicle for
more than 15 minutes, the battery becomes drained). To counter this problem,
a sticker has been placed in the driver compartment to remind the driver not
to let the vehicle to idle for more than 15 minutes.
3. For clarification, please contact MMB, HQ MES at 870-6821.

Task to be taken when
Diesel Engine Vehicle Failed the Smoke Test
1. Before Smoke Test
a. The following steps should be taken before the driver
proceeds for vehicle test:
b. Station the vehicle outside the test centre and apply
engine acceleration - stepping on accelerator pedal for about 5 minutes
(This is to clear the exhaust system of excess accumulated black soot, as
our vehicles are normally not `operating at the optimal engine speed).
2. After Failing Smoke Test
a. If the vehicle failed the smoke test, the unit technician
shall do the following:
i. Clean the air cleaner element with compressed
air.
ii. Ensure that the sediment bowl is free of dirt
and particles.
iii. Ensure that the fuel filter is free of dirt
and particles, and not choke.
iv. Clean the exhaust system by blasting water through
the tailpipe into the exhaust silencer. (Ensure engine is running at
high idling.)
v. Check the quality of the engine oil. If the engine
last oil-change was more than 3 months ago, assess the oil quality and
replace the oil if necessary.
vi. Check the injectors and replace them if necessary.
NOTE: Units that ensure S/No 11 is done before the
smoke test, would better prepare their vehicles for the smoke test.
3. After Failing Smoke Test Again
a. If the vehicle failed the smoke test again, send
the vehicle to zonal workshop for repair.

Road and Brake Test
Procedure
1. This established road and brake test procedure can be found in the dri-clad vehicle maintenance manual. It has been implemented since Jan 92 by dri-clad centres and LAD workshops.
a. Road Test - When the vehicle is mobilised for Technical/ Basic load, Task Load Collection exercises, there is no requirement for the vehicle to be sent for AVI. For technical / Basic Load, Task Load Collection exercises, the vehicle is required to go for a road test prior to putting the vehicle on the road.
b. The road test is to be conducted as follows:
i. The driver will drive the vehicle within the
camp compound for an approximate distance of one kilometre. The driver
is to report any abnormal noise or vibration on the vehicle.
ii. On a level stretch of even, dry and good road
within the camp compound, predetermine a brake test track. The test
track must have a length sufficient for the vehicle to reach the speed
to be tested in addition to the maximum allowable baking distance and
safety distance. The test track must be well lit and permanent marking/post
made to show the maximum braking distance and the starting point of
braking.
iii. The test can be supervised by any officer /
specialist appointed by the Commanding Officer. This officer / specialist
must be well versed in the testing procedure. The driver will perform
a brake test on the vehicle. The braking times and the distances must
conform to the following table before the vehicle is allowed on public
roads. The conducting officer / specialist will certify whether the
vehicle passes or fails the brake test, the brake system must be inspected
and remedial actions taken to rectify any faults. The vehicle will be
sent for a retest. The vehicle must pass the brake test before it is
allowed on the public roads.

Calibration of Tyre
Pressure Gauge
Extracted from email: Calibration of Equipment dated 19 Dec 97 Hd, `B’ Veh Sect, HQ MES
1. The tyre pressure gauge (a BII item) is a low cost item
and it will not be cost effective for it to be calibrated. It is not essential
for calibration, just as long as it is functional and accurate. Thus, there
is no need for the calibration of this item.

Burnt Electrical Harness
for Fiat 3 Ton
Extracted from email: Vehicle Burn dated 12 Feb 98 by Hd, `B’ Veh Sect, HQ MES
1. GSMB has discovered that the ‘+‘ electrical cable running from the alternator was burnt. It was noticed that the polarity of the battery cables was connected wrongly. When this happen, turning on the master switch will result in a high current (reverse polarity) flowing into the alternator causing the burning of the wire.
2. The possible cause is that technicians may have mistakenly
thought of that mark on top of the battery terminal (indicate negative ` - ‘
terminal). Please remind them to refer to the marking ON THE BATTERY COVER as
the right polarity.

D. COMMUNICATION EQUIPMENT
Go
back to Menu
Booking-in
of Equipment to EMC
1. During GSMB’s zonal visit to units, there were two instances where the units highlighted that R&I, EMC restricted them from sending in more than 20 equipment per trip. GSMB does not practice this policy and we welcome units to send in their equipment regardless of quantity. At times, units may be advised to send them in batches where the quantity of equipment is large. This is to prevent a sudden drop in the unit’s and SAF’s readiness condition (REDCON) status.
2. Units are further cautioned not to accumulate faulty
equipment before sending them for repairs, as this undesirable practise will
drastically affect the unit’s Equipment Availability Rate (EAR) as well as causing
the equipment to deteriorate further (e.g. corrosion). This will also cause
a sudden surge in workload which may lead to a longer turn-around-time for repairs
to be effected.
Back to top
Schedule Appointment
with R & I, EMC
Units are advised to call R&I,
EMC at 870-8229 one or two days in advance to book for a time slot prior to
sending in their equipment. During GSMB’s zonal visits to units, there were
several instances where units highlighted that they had to wait approximately
half to one hour for their turn even though they were punctual for their scheduled
appointment. These were due to the prior units arriving late for their appointment
thus causing a backlog of units. On top of this, the space in the R&I is
limited, therefore we are unable to entertain more than one unit at a time.
As such, R&I would appreciate it if all units could co-operate and adhere
closely to the agreed appointment schedule. In doing so, it will help to expedite
the transaction and eliminate the unnecessary waiting time.But in any case,
units are allowed to send their equipment without any prior appointment.

Equipment Monthly Outstanding Report
These report update units on the
status of their VHF sets and accessories that are held in GSMB and MAC for more
than 4 weeks. The report includes the expected date out and status of equipment.
Units will expect to receive this report from MP & C, GSMB within the first
week of the every month.

Corroded
Equipment
If the corrosion is minor and the
set is still functioning, the technician will just clean it and pass out the
equipment. For those with serious corrosion problem, it is not a case of just
sand blasting alone. Some of them may need a change of casing. These sets will
be referred to MAC and this will require a longer TAT. Units are urged to take
care of their equipment and to sent in corroded equipment to GSMB (STE/CET for
the commercialised equipment) as soon as possible. If units are found to be
negligent, units may be required to bear the cost of repair.
