Working on old bikes (or any old vehicles) you often find connectors full of nasty corrosion. It can cause electrical gremlins that are hard to track down, reduce the power getting to your lights, and even stop the bike from running at all. You can painstakingly remove every contact and hand clean them or you could do this.
Step 1: Disconnect the battery. Seriously, you really must do this.
Step 2: put enough white vinegar in a plastic sandwich bag to immerse the connector.
Step 3: Make sure you really did disconnect the battery, then go away for a few hours.
Step 4: Remove the bag and discard or to another connector.
Step 5: Rinse it out with clean water and if possible blow it dry with compressed air.
Step 6: Fill the connector with dielectric grease, including packing it in the back side.
Snap it together and ride! :moped:
