As you know I was having charging issues with the big burger.i fixed this buy tracing it to the rectifier and have just brought a electro sport one then all fixed or so I thought.? My first concern is that the battery is now charging at 14.4 volts right of idle but doesn't go any more than 14.5 even at 8000 rpm IS this ok and should I be worried.as the baterry is not overcharging.now my next concern is the code c50 comes up now and then should I be worried about this code as the bike rides fine with this showing .any help on these two concerns would put my mind at rest brilliant site by the way

Aniversary, this is my post number 1111


The rectifier/regulator is working exactly as it should.

The C50 code is most likely caused by a poor connection between the ECU and the CVT-controller, which are two separate entities on your K3 model, both located up front, underneath the instrument panel.

MALFUNCTION CODE: C50
DETECTED ITEM: CVT serial communication
DETECTED FAILURE CONDITION: No signal is supplied from CVT control unit to ECM for more
than 5 sec. after starting the engine.
CHECK FOR: Wiring/coupler connection.

You might check the harness ground under the battery tray, mine intermittently threw code 50 until I found a faulty connector.

Thank you all for your replies the FI light didn't come on today at all and that was a 50 mile ride to the coast so all well and good.must of been the lack of charging from the rectifier that throw up the code because the cvt motor has to get 7 volts

The code has come back and then gone away again several times you say the earth is under the battery box can I just remove this box without moving any other panels just the battery box plastic which I believe is one panel thanks for any advice and by the way great very helpful site

My 2002 build K3 has been throwing C50 intermittently for 5 years. I have now learnt to ignore it, there has been no impact from the C50 code on the way the bike runs, in any shape or form.

The code doesn't apply to K5s and above, as the CVT controller and ECU are a single unit.
