My IP67 12V / 17A has been working fine until today, when it failed to charge the 135AH AGM in my motorhome. I had to pry the inline fuse holder open so figured it must have a problem. I wasn't prepared for what I found! I've had this about 12 months.
Can anyone shed any light on what has happened here and why?
Also, is this covered by warranty?
Poor quality fuses - not fit for purpose. Known for high resistance contacts, causing heat and melted fuses. Often the plastic will melt and not the metal, so they are also a fire risk.
Change it to a MIDI fuse and your problems will go away.
On further reflection, the fuse hasn't been touched since purchase of the charger, and the vehicle has been stationery for 2-3 months, with the charger having been run perhaps 6 times... I wonder how the fuse contact would have differed? I mean, this could have easily been catastrophic, couldn't it?
For other people's reference, I'll include a link here with a good detailed explanation, answering my own question of how the fuse contact can differ, or deteriorate. It is worth being aware of for sure.
