Trig Posted January 17, 2009 Share Posted January 17, 2009 Was driving along today, the cat sensor and batt light started flickering, then stayed on, then dash lights died, then headlights, then the car died. Luckily it died as i was on my driveway. jumped it and i checked the pulley was spinning. everything seemed ok. im guessing this means the alternator is knackered?

Luckily it died as i was on my driveway. jumped it and i checked the pulley was spinning. everything seemed ok. im guessing this means the alternator is knackered? dash lights wouldnt die before headlights alternator would power all the car even if you took battery out also battery would power most stuff for about 20 minutes without the alternator charging check the voltage on the battery 13.0v plus (disconected) check the voltage under load check the voltage on the alternator output should be higher than on the battery terminals @ 13.8v could be just the rectifier on the alternator if alternator gone either have very high voltage eg 15v+ on output or very low voltage eg 11-12 v check cells in battery aswell (need topping up maybe) could also be a majot ground cable loose. check grounds to engine block and grounds to body. and check battery terminals put new battery on and if all electrics run ok you know its not battery Quote Link to comment Share on other sites More sharing options...
Trig Posted January 18, 2009 Author Share Posted January 18, 2009 (edited) dash lights wouldnt die before headlights cheers for the reply, they pretty much died at the same time. will check the voltages etc and come back PS battery is less than 6 months old Edited January 18, 2009 by Trig (see edit history) Quote Link to comment Share on other sites More sharing options...
spiderpigcity Posted January 18, 2009 Share Posted January 18, 2009 cheers for the reply, they pretty much died at the same time. will check the voltages etc and come back PS battery is less than 6 months old if alternator faulty and overcharging it would destroy your battery in a few weeks by boiling it dry i would check the grounds and connections before you assume its alternator Quote Link to comment Share on other sites More sharing options...

Terminator Posted January 18, 2009 Share Posted January 18, 2009 Check the battery. negterminal connection. I had a similar problem, the clamp had worked loose. Car was totally dead, gave the clamp a slight twist and everything came back on. Quote Link to comment Share on other sites More sharing options...
