Help! Losing all Electrical power
I'll try to make this as clear as possible...
The other day, the bike ('01 RC, full Ack exhaust + flapper mod) cut out a couple of times under hard accel. Both times it happened in second, around 8K or so. This was like a hard hiccup, the bike lurched hard and then accelerated normally through all the other gears. This happened twice that day.
Later that night, the bike started stuttering and bucking badly, the cluster flickered, and the FI light blinked on and off, and the bike stalled a couple of times.
I turned around and headed home, and as I was cruising at a steady pace on the highway, the bike started stuttering and lurching again, FI light blinking again, and stalled again, cluster still on. I started it back up and road for a short distance, the bike stuttered and lurched, and then lost ALL electrical power and died completely.
I had the bike towed home since I was in the middle of the interstate about ten miles from home.
The next day I checked connections at the battery and they were solid.
Then I tapped on the ECU itself, and the power came back on. I checked battery voltage, and it showed 12+ volts. The bike fired right up.
I then removed each of the pin connectors from the ECU and checked each pin to see if one or more of them was loose, they were all solid.
I plugged the ECU back in and with the key switched to "ON" I wiggled each wire connected to the ECU and watched the cluster to see if it would flicker, indicating a loose connection. All the wires were solid.
(I just bought this bike, the previous owner installed the undertail, and did not fasten anything down correctly inside, including the ECU and taillight assembly)
I decided to ride the bike a short distance down to the beach to see how it would act. Just as I got there it started sputtering and bucking again.
I took the pillion cowl off and tapped on the ECU again, the juice came back on.
This time when I tried to start it, I heard what sounded like a circuit breaker opening (*click*) and the power went out. Each time I tapped on the ECU, I got the power back, but would lose it again when I tried to start it.
Finally I got it to stay running again, and was able to get the bike home.
Are there any circuit breakers back there that would open the main circuit? Whatever is opening seems to be inside the ECU, since tapping on each of the relays (?) back there did nothing. Could there be a circuit breaker inside the ECU for some reason?
Can somebody post a wiring diagram?
