I have 95 izuzu and the battery light came on due to that the battery it's. Running low what could be causing the problem?
Most likely the alternator has failed, you could get a small battery charger to bring the battery back then take it to some one that can test the charging system, my book shows 2 systems that could be in your Isuzu depending on build date. One system has an alternator drop out circuit that is controlled by the ECM, the other is a normal internally regulated system, it looks like both systems use the same alternator.
