Melted Fuse

Posted: one year ago Quote #1217
I have a AP730 Battery Pack which is 15 months old and only used approx. for 2 months with a 105amp hr battery fitted.  I have just experienced the display indicating that the battery had 0% charge left.  I tested the battery and found that it was fully charged.  I then checked the fuses and found that the Main 10A fuse was melted into the socket.  It took reasonable force to remove the fuse with pliers.  The fuse had not blown but just melted on one side. I now cannot push a new fuse completely into the socket.  The display no longer works but the USB light does. I am very concerned that it could have caught fire.  Any suggestion please.

Exactly the same issue. Getting open circuit and polarity warnings as well. Assume the fuse does not contact properly now. Display disappears once power from charger is cut.

Yes that is what happened to mine.  Sent it back and they replaced the fuse box.  No problems since. Very dangerous given it sits in the back of the car in the garage and could cause a fire.

I had the same thing happen to my AP730 melted the fuse and the lid around it while in the back of my 4X4 the night before we were to leave on a holiday.
I took it back to the place of purchase and got a replacement.
I am still concerned/worried that if it happens un noticed a fire could start in the vhicle.

Hi Phamto

thank you for your question the answer would be to check the 10amp main fuse is still good from your description of the problem it would be my opinon your 10amp mains fuse has blown.

look forward to your update on what you discover.
