I have a wonderful old 1985 240 Volvo that has never let me down (5 years now) but yesterday i got into the car, turned the starter and notice the alternator dash light up,..big and bright. So truned off and when ignition was on found i had no dashboard warning lights. once started again i found no indicators working although head lights and flashers still work. Driving home also noticed that the rev counter did not work either. I sduspect a failed Alternator but would appreciate a second opinion. If so, is it normal they should fail so suddenly with no warning.
