There is no relationship between the gear box and the alternator regard to the movement of the car, so your problem is elsewhere, most likely in the transmission system, the road wheels or the braking system. The turning off could be as a result in stiffness resulting from the problems mentioned above.
something is causing a drain on the battery when switch is turned off
i would start by testing the battery , i have seen cases where the battery was good enough to start the vehicle but was causing the alternator to do all the work resulting in premature failure. my f150 went through a brand new ford alternator in 2 months .
Due to the layout of the cd20 in a Serena it is not uncommon for the alternator too run at high temperatures. However the alternators that were fitted originally were capable of dealing with the required heat stresses. As long as the alternator is a good quality one it is normal. These engines do use alternator belts quickly so that is not unnusual. hope this helps.
Is the alternator a known good one? You could have a bad rectifier in your alternator causing a short to ground when it is installed.
Alternator causing interferance.
By causing the energy to turn a generator/alternator.
on the alternator on top is a bolt losen that bolt and it will allow you to move alternator causing belt to losin
Probably have a 'parasitic load'. This is something causing an abnormal battery drain while the car is off.
It is most likely a bad diode in the alternator that is causing both lights to stay on. Or its just your alternator going out, replace alternator, and check pads an rotors.
All that would be left would be a short in the wiring to the alternator.
Yes, alternators are designed to maintain the battery, or recharge a battery that has been slightly discharged from starting the car. When the alternator is used to recharge a dead battery, it causes the alternator work harder and longer than it is designed for, causing it to overheat, thus causing damage to the alternator. A battery charger should be used instead. They are designed for charging dead batteries. After the battery is charged, let the alternator maintain the charge.
