Just a question if anyone can answer it. Is it normal for the car alarm to go off as a very flat battery is being charged on the car and recovers it's voltage?  |
This can happen because if you have a pump running when the alarm is set the voltage sensor with in the alarm will pick up power consumption of the pump. surprised it lets you set it at all. Though if it is not sensitive to pick up the discharge when it is fully charged as the battery voltage goes down the amperage drawn will increase the good old V=IR equation you would have been taught at school. Also you should never charge the cars battery is connected to the car. You can blow the diode pack in the Alternator by charging the battery whilst it is still connected to the car. So nothing should should be live when charging the battery.
