A quick recap, previously the battery stayed charged if I unplugged the alternator. That has been my routine every time I stop for a while. Pop the bonnet and unplug the alternator. So its not the battery.
This has been a problem since April and have fitted two replacement alternators without success. The joke's wearing a bit thin. Any thoughts?
