LED Flash Relay Modification

Just found a link http://www.600rr.net/vb/showthread.php?t=294551 , written by kritip



This applies to EU and other bikes with hazards and 4 pin relays, type Mitsuba FR33-025 (however, if you show me the insides of a 2 pin I can advise as well)


Cut into the relay case, very carefully, and don't go deep. From about 1.5cm to 2.5cm from the top of the relay on the printed side, roughly where you should see >PBT+GF30<. Do not cut deep as the circuit board is only 3-4mm away from the plastic casing.


There you will see the flasher IC chip...its a freescale MC33193:

Simply, and carefully cut pin 7 or the copper track that links it so it's not linked up anymore....that should do the trick. It's very easy to apply a bit of pressure with a small tipped screwdriver to the top of the leg of the IC, and it will snap off.





BE WARNED THAT PIN 7 IS THE FAULT DETECTING PIN> so no rapid blinking warning in case of a single bulb failure if u switch back to bulb.
