bnamunds Posted March 1, 2016 Share Posted March 1, 2016 My battery icon warning light on the dash remains illuminated at all times in my 1988 LR 90. It used to extinguish a few seconds after I started the motor, now it stays on at all times. It's been like that for a few months now, and the alternator seems to be adequately charging the battery. Anybody have any idea what might be causing this? Quote Link to comment Share on other sites More sharing options...
neil110 Posted March 2, 2016 Share Posted March 2, 2016 I had something Similar for a while, it turned out to be a poor connection for the brown/yellow lead on the back of the alternator. It was still charging but not at full capacity. I have a battery condition gauge which gives an indication of the level of charge the battery is receiving.

dailysleaze Posted March 2, 2016 Share Posted March 2, 2016 Check the fan belt tension. Seeing as yours is 1988 (200Tdi conv or earlier) it won't have an automatic belt tensioner and could have been set wrong. The wiring as above is probably more likely though Quote Link to comment Share on other sites More sharing options...
Tanuki Posted March 2, 2016 Share Posted March 2, 2016 A failed diode in the alternator rectifier-pack can cause this. Quote Link to comment Share on other sites More sharing options...
