Good morning, Occasionaly my radio loses power when I apply the brakes on my 1996 850 turbo. Has anyone else experienced this problem. Is there a simple solution.
Apperciate any help or ideas, Thank-you

Nope. But those "radios" have a great sound, very loud and very good.
The radio turns clear, goes off signal, no volume, zero. Never happens with the heads light on, at night for instance. It's a voltage problem, when there's a voltage drop due to low engine reverses. For instance, 12 volts stopped. Then 13 Volts iddling and increasing up to 13.8V at 1,500-1,700 RPM, then keeps 13.8V. The radio doesn't like that, or there is a problem with the voltage regulator around 1,600 RPM.
I really doubt it's a voltage problem. The radio should work fine down to about 9V at which point the lights would be so dim you could hardly see, and the problem would be worse with the headlights on.

Yes, would be worse with the headlights on. Maybe I use only CD at night. Actually always CD. As long the voltage regulator works fine, I don't care about the radio. But from times to times it happens, always during day light as I remember, and at decceleration always. Never noticed that brakes could have anything with it, why and how?
The radio can work fine down to 9V, but the radio doesn't like voltage changes, because the radio is fine tunned in resonance at a gives frequency, and I bet the LC resonante circuit that tunnes the station doesn't like voltage changes, because it tunnes automatically, and so on...
Simply forget the problem, there's nothing to fix. Can't have it all.
You can't be serious?
The radio will have a regulated power supply within it, an automotive electrical system is notoriously filthy. Modern radios don't use a tuned LC circuit anyway, the tuning will be digitally synthesized.
I'm betting on a loose connection somewhere, if you say the brakes are not related, it's probably the mechanical motion of slowing down.
There's no way this is a voltage problem though unless the lights are dimming severely at the same time.
Good morning, It has only happened during the day (so far) so I cannot tell you if the lights are diming or not. Since it is now happening more often I will pay more attention to night driving.

Digitally synthesized or not, there is a tuned LC circuit somewhere. Radio signals are electromagnetic waves that have to be driven at resonance at a given frequency. Electronically it can only be done by a matched circuit composed by a series inductor and a capacitor in resonance, so that "motion" is amplified at that specific frequency.
A seven years old lose connection, even after several radio removals to fix the CD in/out system ?
Can't notice anything on any light, not even on the radio. Nothing lose exists, not even the motorised antenna is lose enough to be the cause, since it only happens at around 1,600 RPM de-accelerating, once in every 10 to 20 times it could happen.
The problem remains exactly as it was 7 years ago, since I've buy the car (850 T5 1996).
