Radio Power Supplies - Help!!
Heres the problem.
When i connect a cd/radio unit using the ISO connectors within the standard wiring loom I loose the memory settings when the car is switched off.
This happened to a Kenwood unit ( i sold it because i thought it was faulty) and now a Sony unit.
I have checked the permanent live and this is showing 12 volts even when the ignition is switched off.
There is also a Laserline alarm/immobiliser fitted. Would this cut all of the power supplies when in use?
