Mariusz Posted May 11, 2010 Share Posted May 11, 2010 Well guys I am puzzled with this one!! After not using the supe for a few months.. she needed jump starting , battery was so dead there were no dashboard lights. It was a new battery placed replaced in december. After the jump start and giving a few rev's for a short while , she decided to be nice and move. I drove her for 3 miles and keprt the revs up then pulled in. She stalled and wont start alone. The dashboard lights are still on so does that mean that the alternator is workin still because i presume the battery has held some charge?? The aux drive belt does squeal alot tho !

chrispot Posted May 11, 2010 Share Posted May 11, 2010 sounds as if your alternator is charging but i would get a new belt possibly, also if the battery is left dead flat for a long time it damages the plates inside and then doesnt hold a charge or has less capcity, try charging the battery over night, just giving it a 3 mile run i doubt this would be long enough to charge it fully from dead flat. regards chris Quote Link to comment Share on other sites More sharing options...
bluecoup Posted May 11, 2010 Share Posted May 11, 2010 you need a much longer run than 3 miles, as above stick it on a charger overnight, and go from there, but if it was so flat that you couldn't even light the dash you could have killed it Quote Link to comment Share on other sites More sharing options...
Dr_Doom Posted May 11, 2010 Share Posted May 11, 2010 The aux drive belt does squeal alot tho ! Crank Pulley? It could be slipping causing the belt to not move around properly and charge the alternator. It's not uncommon for it to have completely separated.

jagman Posted May 11, 2010 Share Posted May 11, 2010 You need to fully charge the battery over a longer time -fast charging can knacker the battery jump starting , get the car running and the alternator "sees" a low battery voltage so its regulator puts out maximum voltage and current - this loads up the alternator and the extra torque required can cause the belt to slip/sqeal 1 start of an engine can take 10-20 miles to replace the charge for that start alone ,let alone charge the battery If you leave the car parked up worth getting one of those sunlight powered trickle chargers and plug it into the ciggy lighter-they are only about £15 -wont do much if you park in a garage:innocent: Quote Link to comment Share on other sites More sharing options...
Mariusz Posted May 11, 2010 Author Share Posted May 11, 2010 (edited) I have started charging the battery. The battery charger is displaying that the battery is fully charged??? If thats the case , what is going on?? Could it be a terminal / connection problem? I am puzzled?

If thats the case , what is going on?? Could it be a terminal / connection problem? I am puzzled? could be that the battery is f*cked, if one of the cells gets a high resistance, the battery charger cant push anything through it and the voltage goes up and the charger thinks that its charged, the charger may still be put out a small charge when it says its full, if this is the case i would leave the charger on over night it may help, retest next day if no good take it to halfwits and have boy test it for you, good luck regards chris Quote Link to comment Share on other sites More sharing options...
PhatB Posted May 12, 2010 Share Posted May 12, 2010 If you have a multimeter you can check your alternator is charging the battery. Should be around the 14 volts with the engine running. If not then its the alternator/belt slipping. If it is charging, check the voltage of the battery with the engine off. Should be around 12.6 volts. If thats ok leave it overnight and check the battery again in the morning before starting the engine. If its below 12.3 volts then you probably won't be able to start the engine and suggests to me that the battery isn't holding a charge.
