I don't kow why my 2001 S60's radio started draining the battery but it is. I don't want to install a new system as I like the looks of the factory system.

Currently the radio is unplugged. I would like to cut the power wire, install a toggle switch that will break the power connection so it can't be drained when the car is not running. If I understand correctly, when the switch is on the off position, it should act sort of like a circuit breaker being turned off. When the switch is turned on, the radio should be fully functional. Is this correct?

I am assuming that there may be a constant power connection that is used to keep the radio memory, presets etc. Should I worry about this and install a second switch or can it be put on the same switch as the main power?

Any ideas here are greatly appreciated! Also, how do I pull th radio out? Is there a special tool?

 

The radio is a module in a network.

 

Can you explain what you mean by this? Will my idea work or not?

 

It might but it might also mess with the rest of the computers in the car.
The entire car is in a network. You car has like 15 computers all linked together.

Are you 100% sure it is the radio?
When you check for a parasitic draw you need to leave it like that for atleast 15 to 20 minutes for the car to go to sleep.

 

best bet would be get a new or refub. radio to prevent future problems
