This stereo has been in there for years. Why now?
So weird. |

You said this happens "when driving". Is it happening while the car is stopped?
You may have a loose power or ground that is swinging with momentum as you decelerate and loosing contact. Then is comes back to rest and reconnects. I've seen it happen. |

Happens when the car is stopped and not moving.
Its something in either with switch or wiring. Will be check tomorrow (assuming I can find some time). |

Does it happen as soon as you touch the pedal or after a bit of travel?
Trying to see if it's the brake light switch or a physical interference. Can you activate the brake switch by hand and see if that causes it? |

Been busy the last few weeks.
Going to be looking at this again this week. In addition to the light testing method list above, I plan to check all of my grounds. Here's my list of grounds: Battery Trans Relay Board One under dash from stereo I've checked and cleaned my fuse block. As mentioned before, I get the same issues with the directionals. Any other hints or suggestions? Please let me know. Thanks! |

Finally had some time Sunday to take a good look.
Cleaned the grounds, particularly the one directly from the radio. MUCH better. It still happened once this morning on the way to work, but that's it. Thanks all for your help! |

I too believe this is a voltage issue. I had the same type of problem in my 928 when the voltage regulator was going out. It was fairly intermittent at times too. Mine would shut off the radio because it is the most voltage sensitive item on our low tech cars. I found it only happened when the car was down to idle, is yours doing this also? If I came to a stop and kept the revs up a bit (keeping the alternator charging) it would never shut off. It was most prevalent when driving in the rain because the wipers were using even more voltage.

Do you have an MSD in the car?
if so...I bet you is hooked up to one of the wires feeding the MSD... |

I just got a 914 ('74 1.8) and am having a similar issue with the turn signal turning off the radio. The radio is after market. Thanks |
