To explain, I repaired a Clarion/Jaguar push-button radio/cassette player dating from the 1970s-mainly a cassette fault, and, as ever, fully tested it on my bench, before sending back to it's owner, who lives many miles away from me. A few days later he reported that, when he refitted it to the Jaguar car from whence it came, smoke came from it, after which the Cassette Player continued to work, but not the radio. As I don't drive it would be difficult for me to travel to where the owner lives to check things, but I'm wondering what the fault is. All the connections on the stereo are original, and consist of a fused DC supply, two pairs of wires for speakers, a switched +12v line intended to operate an electric aerial relay, and a lead intended to be connected to the dashboard lights circuit to operate the two panel lamps in the radio. All I can think of is that maybe the aerial relay circuit in the car is faulty and overloaded the +12v line, which is, as usual, supplied via the radio's on/off switch. What it burned out in the stereo I obviously don't know, but maybe a length of printed circuit track.
The point of this post is that I'm wondering if carrying out repairs for anyone who lives beyond travelling distance away is a good idea, though over the years I must have done so many times with no problems until now. What do other members think about all this?
