Question : I WILL be overseas for
My car will be left untouched.
I feel that having someone merely start and let it run idle for 15 minutes or
so daily or every other day will be more harmful ( to the atmosphere ) and gives
no ( technical ) benefit to the car.
Thus, I am thinking of disconnecting the power source ( ie the battery ) and
let the car be "dad" during my absence.
Will this affect the circuits of the various systems, such as the alarm
system, immobiliser, etc ? When the power source is re-connected on my return,
would the various systems require re-tuning ?
Alternatively, if the car is left as it is during the period ( battery
connected, no warm-ups / idling ), will the battery be drained excessively ?
Leaving the batter connected when you are away for long periods of time would
result in the battery being drained by the clock and some other equipment that
may draw small currents even when on a standby mode. Disconnecting the battery
would be a better idea for the short period that you would be away.
One month disconnected would do no harm to the battery and there should be no
problem when you reconnect it.
