Guest dolly1350 Posted April 29, 2011 Share Posted April 29, 2011 Have 1995 mk iv which has been standing for nearly a year. Started ok but appears to be running on the battery. All warning lights except abs, engine management and oil light are staying on. Could this just be the alternator? Got 11 volts across the battery on a multimeter when the engine is running. Also what is the orange oil can display top right of dash? Many thanks if can help. Link to comment Share on other sites More sharing options...

Guest ugp Posted April 29, 2011 Share Posted April 29, 2011 Alternator's not charging. Should be 14.4. When my battery went flat (with the car running - dodgy alternator) I got the oil light too. Have you actually got oil in it? As soon as I changed the battery / put leads on it, the light went out. Electrics go haywire when voltage drops. Stick another battery on it and give that a go.

Guest dolly1350 Posted April 29, 2011 Share Posted April 29, 2011 Have already done that oil level fine Link to comment Share on other sites More sharing options...
Guest ugp Posted April 29, 2011 Share Posted April 29, 2011 Put a different / new battery on it or a booster pack if you've got one. If the alternators not charging you will get the alternator light on (also the low reading across the terminals) but also electrics playing up due to not enough juice to run it properly.

Guest dolly1350 Posted April 29, 2011 Share Posted April 29, 2011 Have tried second battery but has made no difference. Can see no other alternative but to change alternator? Link to comment Share on other sites More sharing options...
Guest ugp Posted April 29, 2011 Share Posted April 29, 2011 Whats the reading from the 2nd battery? If that isnt at least 13v your going to have eleccy gremlins Link to comment Share on other sites More sharing options...
Guest dolly1350 Posted April 29, 2011 Share Posted April 29, 2011 Fully charged battery now on reading 12.18 no change. Cost for new alternator £280 so will try to get a refurb. Link to comment Share on other sites More sharing options...

Chris Wilson Posted April 29, 2011 Share Posted April 29, 2011 All warning lights on usually indicates a failed regulator or diode pack in the alternator. the brave can rebuild them, the not so brave look for a good used unit. Often the cause is a leaking water pump dripping water into the alternator. Check the little nipple under the water pump for water seepage.
