Hi, is there any troubleshooting guide for hfs3 v3 to point me to? My problem is that as of recent, my kit fails to work properly, so always, when i depress pedal, baragrapf won't read anything, just failsafe kicks in. i checked all wires 3 times around, so seems like now is the time to do diagnostic via jumpers on circuit board..however i have no idea what results i am supposed to get.
