• Cracked cover, failed seal or damaged cable glands

🛠️ Service Notes

• Isolate the batteries before opening a junction box, and photograph or label the connections before disturbing anything
• Mount it where it stays dry and reachable, the right way up, so the lid can still be removed and any water that does get in can drain
• Bring cables in through the glands or grommets provided, from below where possible, and leave a drip loop so water runs away from the box
• Make the connections clean and tight on the correct terminals, support the cables so nothing hangs on them, and refit the lid with its seal properly seated
• Check the circuits work, and that any fuse ratings match the original, before returning the engine to service
