Radio works perfectly when parked and upon accelerating all power to radio is lost and returns as soon as I come to a red light or stop sign.

I removed the engine ground strap and cleaned the areas where it is attached. I grounded the radio body to the lighter ground wire. I ordered a digital lighter digital LED display Voltmeter that will arrive tomorrow. The alternator is 32 years old and the car is original and in showroom condition inside and out with 120 thou miles.

  • A loose connection behind the radio - someone fitting an aftermarket radio may not have checked all the connections... – Solar Mike May 29 at 13:50
  • Or another possible is a dodgy battery that isn't supplying enough voltage/current when under load (although I wouldn't expect that to really happen under acceleration as much...) – Rory Alsop May 29 at 22:37
