SBS9120D on 31. Battery empty. What a joke. Last trip
11.20pm towards TPY. Bus just went off right
after Bedok North Ave 3 Junction. Everything went off. BC
couldnt print ticket couldnt call OCC, couldn't start engine,
couldnt even flash double signal :p. Only use his HP, :p Change to
next bus SBS8837B.
Overnight parking bus. Probably day before just come back
refuel, forget about battery :p today running since 6am until now,
I wont be surprised battery empty. Engine kicking and A/C very cold
though.
There is no need to charge the battery. It is charged by the
alternator.
Electricity is needed to run the A/C and interior lights,
validator, EZ-link readers and the engine(Via the glowplugs).
