This morning, I did some troubleshooting on two of three the electrical issues I had experienced last night. First thing I looked at was the right turn signal issue. It was due to a loose bulb. It doesn't lock into the socket very well, and as a result, worked itself loose. So, I put a dab of silicone sealer on the side of the bulb, and inserted it back into the socket.
The next thing I looked at was the issue of the headlights suddenly not working. That one took about 5 seconds to figure out. One half of a connector, which connects the main power feed wire to the headlight relay harness, broke apart for no apparent reason. I sent an email with pics to the manufacturer, which fortunately is a small operation.
