Can anyone help with this?

 

My wife's 89 Sporty is suffering a strange elect problem. After riding about 15kms (so when the motor is nice and warm) the indicators and brake light stops working. The headlight and tail light however remain functional.

I have had a look at all the wires I can see and none of them are exposed and shorting out.

 

Any advise/help/stories appreciated.

 

Cheers

 

Steamer,
There is only only of those relays and it lives under the seat. It was resting on the side of the oil tank but I moved it so next to the rear guard (still under the seat) to keep it away from the heat of the oil tank but this didnt work.
Any other thoughts?

Relays (the square black ones anyway) usually aren't expensive - so why not try swapping it? Contacts, solder connections etc have a habit of fucking up over time (including them expanding away from where they are meant to be when heated up) and it never hurts to have a spare hanging around anyway.

Thanks guys, so far the new relay (total cost $5.95) has worked. Need to go for a much longer ride to test it properly though
