ABS light stays on

[fatboy]

Hi
I recently had a problem with a bad earth from the battery. Both high beam headlights bulbs at the same time and the abs light came on. I have sorted out the bad earth and headlights are working fine now. The ABS light will go out when I pull off but after a couple of hundred yards pops back on again. If i stop the light goes off after a few seconds.
I have checked the error codes and I have 3, power supply voltage under/over and front wheel rotation signal abnormal (sensor or rotor missing, too large clearance, rotor tooth worn or missing.
I had a sparer sensor and rotor lying around so I have fitted that and still have the same problem.
Do I have to clear the faults 1st ?. If so how do I do that, I have tried but failed.
Can I still ride the bike?
Any help on this would be gratefully received, I have very little hair left to pull out.

Thank you

Managed to clear the faults codes,but abs still the same. Took the bike for a spin and then checked for fault codes. The only fault was over voltage. I checked the dash display and it was reading 16v, if memory serves me it was normally around 13.5v. I am guessing this could be the cause of my problems. Have ordered a replacement rectifier/regulator so will hopefully will resolve my problem.

Mine normally reads 14. Something on a ride I can't recall the last digit and when it's plugged it to my oximser charger between 12.7 and 13.7 normally hope you have sorted it

Hi Fatboy.  Where exactly was the poor earth connection which caused the light problem?  Will be interested to hear result of new R/R.

Good work on the ABS unit.

Earth cable to the frame was the short. Noticed this morning the battery was reading 16v and the abs light was on but when the voltage dropped to 15.2v the light went off. I am reasonably sure that the over voltage is behind the problem. Got a r/r for £39 so a cheapish fix I hope.

New rectifier/regulator fitted and everything working great. Battery voltage showing 14.5v and abs light going off.

Nice one. Sounds like you saved it just in time, before something expensive got toasted!
