My Runke charger stopped charging half way through a regular charge cycle in a cool garage (70F or thereabouts air temp).
The 20A fuse on the outside is blown. Replacing the fuse does nothing, so I removed the charger from the bike to troubleshoot further.
There is voltage at the connector to the charger, so the cabling from wall to charger seems OK.
No burned smell or visible issues from the outside.
I am about to take it apart. Any guidance on where to start, what to look for, how to open it properly?
Again, this is the gold Runke, revision 4.0.
