Where did those indicators go?

    I bought my current 82 R100RS a year or so a go. It had a intermittent problem of indicators not working. I replaced the original indicator relay with a new BMW one from Moto bins. Problem solved. Now a year later.

    Over the last couple of days. The left side would stop working and the right side would work or visa versa. Today I have no indicators at all. Looks like I will have to dive into the headlight shell and have a poke around. Any suggestions on where to start?

    Start by checking every connection. Sounds to me like you have a break somewhere. Could be in the shell, but could be almost anywhere.

    Every winter I do a bit of a strip down on my bikes. Take the tank and seat off and go thru all the connections. Make sure they are all nice and clean and tight. Open up the headlight and clean all connections in there. That way, I don't have any electrical issues during the riding season.

    I feel it could be a bad earth or maybe some thing simple like the indicator relay may have blown.

    I solved the problem of missing indicators. A few people suggested that my problem could be related to the indicator switch itself. I felt the problem lay, in that the relay itself was not getting power to flash. I borrowed a friends power probe to check the indicator switch was not problem first before moving on. The switch tested correctly.

    I traced the green power wires from the indicator relay back under the tank and found some DIY wiring from a previous owner. A home made fuse holder had wiggled part way out and would connect on bumpy roads and not work on smooth. I ditched the faulty fuse holder and now the indicators works as they should.

    That was a nasty bodge. I hate those crimp on connectors at the best of times. At least you haven't got to buy a new indicator relay they aren't cheap. My 100/7 has just decided to leave the warning light on permanently even though the indicators work fine, looks like £45 for a new relay :cry
