Reply To: Bike won’t start – GV 250 EFI 2015
Is there a chance of stripping the bike again and looking for any burn marks along the harness ? also where cables bend at the steering head + under the seat, look for fraying / chaffing ? Check the sprocket cover and see if magneto cables have any fray or chaffing ? If the Right Hand Switch Gear works (all buttons) , you wont need a meter on there, but make sure its black connector under the airbox is clean from any rust , debris etc that might disturb the signals , as the ECU does use the Kill Switch to communicate error codes to the dash when user flicks it 3 times fast before starting. Since you can get a contact cleaner and air spray, spare a day where you can clean every single socket you can find on the bike and let it dry overnight. âš ï¸ Don’t spray contact cleaner on the ECU! – Only dry air allowed. You can clean the ECU plugs though, it will help with reducing some resistance from pin oxidization, so cleaner signals can pass through. Just make sure its been 24hrs before connecting all your sensors back, so it is fully dried out. it is still spring season, so air is still a bit damp to ride away immediately. 12.5V is OK but 12.8V is a charged battery Running Idle = 13.5-14.5v max 5,000 revs = 14.5V max Any higher , bin the regulator but becareful with TEMU style regulators , they will smoke the bike in minutes , just look at the last post here
Bike won’t fire cold but it fires once working = GT250R 2012
All the wires beneath the seat look fine. (As they’re wrapped in electrical tape for the most part.) Only thing of note is that the cable cover the comes out of the right assembly is bent very strongly. I’ll try the ECU thing in a few hours, will it be able to asses electrical issues? I really thought it’d be the lead wire messing with the ignition. I also checked for a tip over sensor and couldn’t find it for the life of me. + I tried unplugging the kickstand switch and starting, nothing. At least there are a few more things to rule out.
In the morning, I’ll attach photos of the ECU connector, solenoid to battery connections, and the connectors under the front left and right air intake fairings. Please let me know if there’s any other photos that might be helpful.
