When power is off radio loses memory what can i do to put power to memory please sendai cd 789

Both. Check the power line that is supposed to power the clock and memory circuits when you turn off the ignition.

And your player has lost the ability of the laser to focus on the disc - hence the error message.

Sounds like your Memory +12V wire is not connected properly. If this wire does not have a constant source of power then you will lose all of your settings on your radio.

Things that may cause you to lose power through the Memory 12V wire:

• Not hooked up properly to the battery
• Bad battery
• Bad ground
• Loose wires

Boss 637UA manual

The vehicle has a constant power source that needs to be connected to the radio. If a fuse has disconected the circuit then you will lose your "memory" for your radio. Look in the owners manual for the fuse box locations. Use a light to find the fuse that has disconnected the circuit.

the constant power retains the radios memory. you should pull the radio out and check the yellow wire off the back of the radio with a digital multimeter. make sure the key is off. if the wire dose not have 12V+ check you fuses on the vehicle.

Good Luck please rate 4 thumbs up and please leave testimonial

At the back you should have a red, black and yellow (maybe blue). swap the red and yellow over. Yellow = memory [constant voltage] red = live with ignition. Hope this helps. Wayne. Tech Rehab. http://techrehab.t35.com

I would check your connection to the remote wire. I'n my 95 passat vr6 its a yellow wire.

You need to Check the Wiring Harness from the Stereo. There is a Constant Power Memory Wire (Should be Yellow or Orange). This needs to be Connected to the Cigarette Lighter Power Wire for Constant Power Memory. Please Rate My Response! Thanks!

I would suspect that the radio is not installed correctly. There should be 12V present on one wire for retaining memory. There is a capacitor inside the radio that will retain memory for a short time (less than 5 minutes), but you should not have to reset the system after each start. If the wiring is correct, then the internal memory system may be defective and require replacement.
