Hi guys, Thanks for your help in advance. Our Oset 20R has been running strong but all of a sudden weak power to rear wheel. I’ve read all forum topics and similar symptoms point to a faulty throttle. This happened last year and a new throttle solved the problem. So this time I bought another throttle and I’ve installed a brand new throttle and doesn’t help. I’ve run all diagnostic tests from the Oset you tube troubleshooting vids (I think there were 12 videos approximately). Everything passes the test with ohms meter. Batteries all strong, relay clicking, fuse seems to look good and work, etc.
Oset powers on, all 3 throttle lights light up, I hear relay click under seat, when I twist throttle the bike lurches forward a few inches then stops. It doesn’t want to move any further. Even with bike on a stand same thing, wheel moves a bit but that’s it.
Theres no brake drag of any sort so not the brakes.
Ive read some posts about testing the various parts ‘under a load’ what does this mean? Do I twist the throttle full, then check all the various parts?
If it’s not the throttle, then what could it be?
We do ride in the snow sometimes but it’s always been fine. Also, his main battery cable sparked several rides ago because it came loose but seemed to work fine for several rides afterwords so don’t this this causes the issue.
Thank you!!
