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 |

its a very slow errr......long pause...... errr .......click
(IMG:style_emoticons/default/smile.gif) I have looked the wiring over and cant see anything untoward As the fuel pump can be heard running and there is small sign of life in as much as there is power getting to the starter but either not enough to turn it over or the starter has a problem, could there be anything on the relay board that could have been effected? I notice there is a circuit board on the underside, could a track have been burnt out? (there isnt any sign to suggest this, i am just fishing for ideas) |

(there isnt any sign to suggest this, i am just fishing for ideas) No. Since the solenoid engages when you turn the key to start the only circuit relevant on the relay board is good. The connections you haven't tested are where the battery cables are crimped onto the terminals at either end. These can and do corrode internally. I've used jumper cables from the battery terminals to a ground near the starter and the starter battery cable post to provide an alternate current path. If the engine spins faster you have a cable problem. If the starter was working before this issue I would look into this before pulling or replacing the starter. |
