2013 tiger 800 oem fog control circuit question
« on: February 17, 2020, 10:50:12 PM »
Hello,
My oem led fog lights on my tiger are not working properly. The switch will turn green and I will see 12v at both sets of contacts of the relay socket. If I jumper out the relay I can get the lights to turn on but  they are not working with the relay installed. I swapped the relay with my heated grip relay and the relay functions for the heated grips. I was also able to get the relays to actuate it with a 9v battery so I don't believe the relay is the issue. I believe the issue lies with the signal to the relay, either a bad connection or some switch logic. The battery was not in the best state of charge, currently charging the battery now. Anyone have more insight on how the switch works? Does it maintain 12v continually to the relay? Low voltage logic? 

Thanks

There are separate outputs from the controller inside the switch for the green LED and the relay output so just because the LED works doesn't mean that the relay will also switch.

The fog light switch monitors the battery voltage and won't allow the relay output to power the lights if the measured voltage is too low. Wait until you've charged your battery then try again.

Thanks. I was able to turn them on with a full charge and the bike running after a few seconds of idling. Glad to know there is no issue with the fog light circuit but it may be time for a new battery because they would not turn on the other day when I was riding for 30 min which started the diagnostic and questions. The battery is the original so I should not be surprised it is on its last leg.

Another informative reply from T800XC, got to say that he is rarely wrong and answers are written for the less knowledgeable, like me :087:
