Hi , thank the forum for let me open this account, i been reading and there is a lot of technical info to learn from. Well i own our first ATV it is a 08 Sportsman 500 Carb that the kids and me been fixing little by little.
the only issue remain is on the Electrical, actual issues is that cluster never turns off, starter wont switch ground to solenoid and brake light at tail lamps is always on. Start if manually short the solenoid and Run and drives ok, charges ok, havent seen the fans to run yet.

So i opened the SurePower 4011568 and found to bad transistors, one of them is located on Q21 and barely reads D2 (according to Google its a NPN BCW32 transistor) and the other one is located on D30, that one was severely burnt and cannot see the printing on the transistor.

I ask for your help to correctly identify those two transistors, i dont feel like spending $500+ on a new ECM yet, i attaching a picture with the SMD removed:

Thank you in advance for all of your help !
Luis

Welcome to the forums. Couldn't find anything doing the quick search I did. You might have to contact Surepower directly and see if they'll share the onfo.

 

hello. Did you find out what transistors they are. I have broken q 21 and q7
