5 posts in this topic

Hi im working on a 07 trx420fm was blowing ign fuse till i bypassed bank angle sensor. But i still have no power to the coil or fuel pump. Can anyone help ,been tring a few other sights with no luck they seem to be more worried about what the bank sensor is than the problem i'm having thanks for any help.

i think the reason they are worried about the bank angle sensor is because the sensor is most likely part of the ignition circuit. if the sensor reads cam or crank angles it will not give the pulse generated signal it needs to tell the coil to make spark. I f i had the manual to see what the bank angle sensor is for and the rest of the circuit i would most likely be able to put you in the right direction. i will try some research and get back to you.

The bank sensor shuts power off to the coil or fuel pump if you roll the bike but you can bypass it , the street trick riders do from what i read in some forums. Idownloaded a service manual today & i think my problem is the pcm or brain

i would trace the wiring back to the fuse because it sound like you have a short to ground. that is about the only thing that will blow fuses. I would start there.
