But, as I started to check the holder it just came loose:
I had not actually fiddled with this holder since I installed my instrumentation panel at the helm. Which must have been over a year ago. But, obviously I had not seated the fuse properly back then and it had finally become loose enough to make a bad contact. I reseated it and the charger reacted normally. If you compare the picture below with the first fuse picture above you cane see the difference in spacing on the left side of the fuse:
This all goes to show that sometimes what looks like a major problem might not actually be so bad. In fact it might be just a little thing like a bad contact on a fuse that is the issue.
