Hi group,
While searching for a solution to my problem I found this forum so I joined it in the hope of maybe finding an answer here between the Hyosung riders.
I got two problems with my GT650r (year 2015).
The first one is that the battery runs out of power very fast. I bought a new battery less than 2 weeks ago and yesterday when I stopped for a break and wanting to start it again and after a couple of unsuccessful tries it ran out of power and the clock was dead.
The second problem is that after I charged and put back the battery back, the clock turned on but when I press the engine stop switch on is show “CHE” on the clock.
From what I read and saw on different videos it look like the ECU might be the reason for both problems. Now I’m asking you for an opinion as well, maybe someone have encountered the same problem as me.
Thank you for your time to read all this and for any help provided!! -
The first thing is the charging, it sounds like the regulator/rectifier has gone. If the voltage is to low the ecu will not load properly & basically trys to set a base line to allow the bike to run, first check the stator with a multimeter you will find a plug with 3 yellow wires set the multimeter to resistance hold it on one terminal & touch the others in sequence so 1-2-3, 2-1-3 they should all read something like 0.1, 0, 0.1 if any of the readings are above 0.2 or infinity then a phase has burnt out, you don’t at this stage need to measure the ac output as in my experience if the resistance is right then 99.999% of the time the output will be fine, next set the multimeter to dc start the bike & measure across the battery the voltage should even at tickover be above 13.6v increase the revs it should ideally read 14.3-14.4 v if all good if it doesn’t then the reg has gone, carry this out first & report back.
