Initially I used a CTEK charger through the power socket in the car. I used to notice the charge light flashing on the charger. I was getting an unreliable connection. I connected up a fused connection directly to the battery no more issues.
Same here. Worked fine until the cold snap started this winter. Then the flashing started - no way could I get a reliable connection. I now have a fused, wired connection to the battery through the bulkhead.
