3. POOR CRIMPING
It seems just about every 12V electrical connection in a modern caravan will be done with a crimped connection of some description. It’ s no surprise, given they are cheap, easy to assemble with the right tools, and, if done correctly, extremely reliable. It’ s important to check yours as many cablers and DIYers somehow manage to get it wrong to the point that they become dangerous.
Poor quality crimps and unsuitable connectors have likely contributed to this failure.
There are tell-tale signs that the crimps have been done poorly. Exposed wiring, loose connections and damaged insulation on the connections are commonly seen issues. These lead to many of the same problems we’ ve already talked about. Poor connections can lead to resistance, which builds heat. Damaged insulation and exposed wiring can cause short circuits, especially if there are a lot of wires packed together in an enclosed space.
Unfortunately, many of these poor crimps can go unnoticed, and it ' s only when they fail that problems manifest. If you do manage to see any obvious signs of poor crimping, get a qualified auto electrician to inspect your system and rectify as necessary.
These inline blade fuses are a disaster waiting to happen. We see this sort of heat damage a lot in our groups.
