Hello and Antara issue, charging problem
Hey thought i would sign up as this is going to be the easiest way to find a solution hopefully to a ongoing issue with a car we are working on, i would love to see if this forum can help me get this sorted.
We have in a 2008/09 2.2di Antara and the issue wa had was non starter, after a battery test and alternator test with a new battery fitted found the alternator not to be charging the battey but no light on the dash to indicate the alternator to switch and activate charging. After a bulb test on the old alternator found that the alternator was not activating thus not charging the new battery.
After fitting a new alternator found that the alternator could be switched to charge battery only during a small current bulb test.
The wiring coming in from the ecu to switch the alternator to charge showed 12v and when earthed would turn the battery light off thus making is look like a earth issue on the engine.
New earth fitted and old tested, all ok but when the connector is fitted back onto the alt it still doesnt switch the alternator to charge the new battery.
Yet if i bulb test the alternator it switches and charges the battery.
I am stuck as look to chase my tail with it looking like the feed from ecu is good enough but not powerfull enough to switch the alternator?
Any ideas if there is a common problem along these lines and what can be done to fix? Possibly test the ecu?
