YY250T charging help needed By dannytroy (Read 1,259 times)

The OMP RR is by far the best...... If you found my Thread on the YY250T charging issue and my issues that was the Biggest key to fixing my charging issues also.

Did you add cooling to the R/R? I'm a little concerned that since it appears to be a "high performance" unit compared to stock, it will also run hotter. It feels pretty hot to me, and that's without the shell on. I know people add cooling fans, but to do it the right way it would have to be relocated to an area with more space, for the fan to pull in more air.

It does not need it. I was going to but after talking to "name fart" at omp there is no need it is a high performance rr and does not need the extra cooling

CDIs and R/Rs try to mount toward the back away from the motor and front of the seat. Up there not to much fresh air gets to that area.

I moved my R/R, and the relay that replaced the blocking diode, to a location under the seat of my 2011 Roketa, because I hate removing plastic to work on things and had more than enough under-seat storage space. I also added a cooling fan to it, simple 12v lead and ground and attached to the R/R with zip ties. So far that has worked out okay; of course mine is not a high performance R/R. It does get quite warm on longer runs, but have not had any electrical issues. It has occurred to me that some kind of air scoop that eventually routes air to that under-seat area might be a useful modification, but that's pushing the outer limits of my fabrication skills.

Well, it's still charging fine so I guess I'll leave the R/R where it is and hope for the best. I may remove the shell again to check the thermostat, since it's getting way up on the temp gauge in hot weather, and I'll have another look at the R/R location then.

I decided to add an illuminated voltmeter where the radio interface is now. I never use the radio, so I'm disconnecting it, and will use that location for the voltmeter. It will be nice to always know how the charging system is working. I'll hook it to a switched 12 volt lead, so it reads when the key is in the on position.
