Battery Isolator
I have been using one of these Isolators for the last few months, would it have likely to have caused any problems with the techy bits in the car?. Rev. |

Very unlikely----However it might be remotely possible to produce a spike in the electrical system as you break contact with the battery.
Electricity when flowing in a circuit does not like to be switched off. For instance the contacts on your light switches at home always arc slightly as you switch off a light. One of the reasons why, if you have a gas leak in a room and the light is on, you must never switch off the light before the room is cleared of gas. |

Hi Jules. I don’t know much about elektrickery but I can not see how having turned off the electric to the systems in /on the car, can make a big difference.Otherwise, every time you switch off, you would do some damage.

Would this not affect the alarm system? If it does, it would potentially affect an insurance claim - just a thought.

Yes potentially it could if the car stolen as alarm isolated if battery isolated, ,My Car is in a secure garage parked behind my main car so it would have to be moved and between a Merc and a Rover , I think I know which one would be stolen

The system remains LIVE after turning off the ignition however dis-connecting the battery means nothing electrical is working.-- |

Sorry Jon. I ment when you use an isolator switch on the battery. I think Steve in post 4 puts it more succinctly than I managed.

If you have a hi line sat nav unit I suggest you put some form of 'aide memoire' on the isolator to make sure the unit shuts down before you disconnect. I have a label on the battery box to remind me but still forget! So far I've got away without it causing any probs.
