1992 Saab 900S non-turbo.
So, the first mechanic starts welding the oxygen sensor into the newly cut six inch metal pipe from another muffler. He takes a break and a second, younger mechanic gets on top of the engine and does something to the engine. The first mechanic then continues to weld.
Well, according to mechanics 3 thru 6, the first mechanic failed to disconnect the battery prior to welding and killed the alternator and battery. The lead mechanic at this garage said it was a coincidence that the alternator died.
The seventh mechanic installs a rebuilt alternator, battery and four belts.
Now, the problem: The radio can change channels, but no sound comes out of the speakers and the antenna will not automatically go up and down.
Mechanics 8 thru 11 plus a car audio “expert” have absolutely no idea why the radio and antenna do not work. ALL fuses check out fine: inside the engine, under the back seat and two behind the radio. The antenna is basically new and the radio is original equipment.
Can anyone please HELP!!!
