WildPlumDx Posted November 26, 2005 Author Share Posted November 26, 2005 oh aye? mine was 11.93v when it was running but the battery was flat needed jump starting so would this effect the reading ? Quote Link to comment Share on other sites More sharing options...
Ned Posted November 26, 2005 Share Posted November 26, 2005 not if you took it straight of the altenator. should make the same power with flat or charged batt. charge the batt. and try again Quote Link to comment Share on other sites More sharing options...
Guest kris Posted November 27, 2005 Share Posted November 27, 2005 oh aye? mine was 11.93v when it was running but the battery was flat needed jump starting so would this effect the reading ? Hmmm, fckd alternator perhaps. Battery shouldn't drag it down. It wasn't at idle right, this was with some revs? Quote Link to comment Share on other sites More sharing options...
Guest Scheme Posted November 27, 2005 Share Posted November 27, 2005 leave the car at idle, take the reading. turn the lights on and check the reading again, if its below 12v your alternator is wasted. It should be just p around 13v. Quote Link to comment Share on other sites More sharing options...
two_days_late Posted November 28, 2005 Share Posted November 28, 2005 just replace your alternator brushes and try that bro, chances are thats the problem. they're cheap as at repco, were about $8 for my escort and $14 for my vl commodore. cheers Matt Quote Link to comment Share on other sites More sharing options...
