W202 1997. My battery had been fully charged over night and I was rushing to work and connected terminals other way round. They sparked and there a bit of smoke from engine and all lights on cluster went on.
I might have tried start it I'm not sure till my son suggested I check terminals and I realised my mistake.
Car started fine and I managed to drive 20 miles to work. Evetything seems working except radio wont come on. I have couple fuses so I replaced necessary fuses according to fuse sheet under bonnet but still not working.
More worrying is battery red light came on and stayed on during whole journey. What does mean? Is my alternator goosed? What's simple test for this and if alternator wasnt working would battery have managed 20 miles withought dying?
Worried sick. Battery was fully charged but seems weak the 2 times I have started th car during my coffee break 5 mins ago
