Connecting battery charger without the battery connected?
Recently, I heard a lot of horror stories of broken ECU's on 147GTA/156GTA and GT V6 engines.
Someone on another forum said, the reason for this, amongst others, might be storing the car for a long time and the battery going completely flat or removing the battery for a longer period. Basically, the ECU not getting any power for a prolonged time.
Since I'm currently doing some cosmetic work to my car I've removed the battery. The battery has now been disconnected for about 2 months.
I wondered if it would be possible to connect my Ctek charger from time to time just as a precaution.
Is this going to do any harm when the battery is not connected?
Thank you very much for your responses.
