I have had the battery off the car whilst stripping paint and priming etc.... but thought it would be good to turn the engine over and run it for a while to keep things in good health etc.....
I had the battery on the bench to charge it and then put it back in the car but very stupidly put the negative lead to positive terminal and positive lead to negative terminal. I didnt turn the key as I was checking other things when I realised what I had done. I noticed that there was a smell of smoke coming from the alternator area and the tin on top of the engine in that area was warm so suspect there is a connector to the alternator under there? I put the terminals on the right way around and tried to start the engine but it appeared the battery had drained? I recharged the battery overnight but wouldnt start, again the battery seemed low on charge Apart from seemingly screwing the battery, is there other damage likely to have occured cheers David |

Is it safe to put a new battery on the car and try it?
If the alternator is toast, what effect would trying to start it have? |

I would not start by installing a new battery and hoping for best given that you smelled smoke. You likely have shorted wiring now either from melting and possibly from diodes. When diodes fail they usually go open but I wouldn't risk it. At least start by using an Digtital Multi Meter to see if the battery + is shorted to ground. After that I wouldn't even consider attaching the battery until you've inspected all the engine harness wiring starting with the alternator and the ignition coil. |
