    Electrical, Chassis & Lighting
    My 1978 Spider has developed a new feature. After starting the car, pressing the gas pedal causes the "generator" light to illuminate on the dash, more brightly as you press the gas pedal more.

    Product/Vendor Reviews
    I had Jeff Young and his team rebuild the alternator on my 1972 Montreal. They did a fantastic job and it looks just like new. The old one had been covered in oil due to an engine failure experienced by the PO. They could not clean the core, found a new one and put it all back together. Highly...

    When I was out driving yesterday, the radio stopped playing and I noticed that the voltmeter had dropped to nothing. A few seconds later, it went back to reading about 12 volts and the radio came back on. It did the same thing a few minutes later and, this time, the meter stayed at 'zero.' I...
