Question about Yamaha YZF-R6 Motorcycles
You exchanged the ecu box with another vehicle. Did you try exchanging the kill switch or the ignition switch? Also you say you have checked the continuity of the wires. Make sure there are no broken connector pins and that the wires are not broken inside the insulation. The most common place to have a wire break inside the insulation is where the harness wraps around the frame neck. You may have to move the wires around while checking continuity to find this kind of break , then a wire bypass will repair the bad section. If the continuity break is in the kill switch you may be able to carefully disassemble and clean the contacts. I sure hope this helps.

It sounds like something is connected wrong if you have power at a ground.It would be a good idea to go to a bike shop that has one like yours and compare the wiring to be sure you have all the connections in the right place.If you have power everywhere you need it but none from the coils
it sounds like the coils are bad...Does it turn over ? If the frame has voltage you definitley have a bad ground and something is touching where it shouldnt be....It sounds like you have a hot wire touching where a ground should be....That would be the first thing I would look for before you go and buy something you do not need...What size bike is it ? how many miles are on it.
You stated you hooked it to another one like yours....Is it connected like the one you hooked your ECU to ?....I would check and double check ...Take photos of the other bikes wiring system if it is exactly like yours....It all sounds like a wrong connection......Hope this helps .............Metalpoet

If all of the following check out, the Ignition Coils will get power. Let me know if you need more assistance.
1. main and ignition fuses - Check the main and ignition fuses for continuity.
2. battery - Check the condition of the battery.
3. spark plugs - Is the spark plug in good condition, is it of the correct type, and is its gap within specification?
4. ignition spark gap - Is there a spark and is the spark gap within specification?
5. ignition coil resistance - Disconnect the ignition coil leads from the wire harness and check the following:
Measure the primary coil resistance.
Positive tester probe - ignition coil terminal 1
Negative tester probe - ignition coil terminal 2
Primary coil resistance = 0.17~0.23 ? at 20C (68F)
Measure the secondary coil resistance.
Negative tester probe - ignition coil terminal 1
Positive tester probe - spark plug terminal 2
Secondary coil resistance = 4.8~7.2 k? at 20C (68F)
6. crankshaft position sensor - Disconnect the crankshaft position sensor coupler from the wire harness and check the following:
Positive tester probe - gray
Negative tester probe - black
Crankshaft position sensor resistance = 248~372? at 20C (68F)(between gray and black)
7. main switch - Check the main switch for continuity.
8. engine stop switch - Check the engine stop switch for continuity.
9. neutral switch - Check the neutral switch for continuity.
10. sidestand switch - Check the sidestand switch for continuity.
11. clutch switch - Check the clutch switch for continuity.
12. starting circuit cut-off relay - Check the starting circuit cut-off relay for continuity.
13. lean angle cut-off switch - Lean angle cut-off switch voltage:
Less than 65 degrees - Approximately 1 V
More than 65 degrees - Approximately 4 V
14. wiring connections - Check the entire ignition system's wiring. If found to be good, replace the Ignitor unit.
