Title: Indicator fault
Post by: davidrsmith on September 28, 2016, 08:49:10 PM

Hi

Now got the carbs fitted (thanks for the help) I have fitted the airbox and the battery. I have tried turning the electrics on for the first time, all seems ok except the indicators. Moving the switch to either left or right just gives me a loud screeching noise, the bulbs don't light and I can't hear the relay at all.

Anyone ever seen this, I haven't had a chance to fault find on it yet but I guess either the relay is shot or there is a short?

The screech could be the relay if there is a short or could be the audible device depending on what bike

Hi
The bike is a CB550k3 which was imported from the US. So it was built to their standards, on the circuit diagram in the haynes manual it does show a turn signal buzzer, but I haven't actually seen it (not that i've looked) on the bike.

May not be related, but it's good practice to run a separate earth cable to each of the indicators. Sounds like the flasher relay has gone, and take the opportunity to remove the awful buzzer.

Agree 100% with the above advice.

Thanks for the replies, where is this buzzer located on the CB550k3,  I must admit I haven't noticed it?

Fixed, it was the buzzer, as soon as I removed it the indicators started working.

Thanks for the advice.

LMAO, must only be me that likes that buzzer. I still have it fitted to one of my 500s.

Ha ! No you are not alone, I've put one on my CB500 I would not be without it.

But honda asked the dealers to remove them as they sounded too much like crossing beepers to the blind!!

My CB550K3 came with the original buzzer removed so I put an aftermarket one on which isn't too obtrusive. I also changed the indicators to led's and got an led relay at (total cost £10) and that was one of the steps which solved my charging problems (the others being a Phillips Eco H4 bulb and an led stop/tail)
