NC30 elec fault - reg / rectifier ??

Post by Redsbike » Sun May 19, 2019 5:31 pm

Hi,

As the subject says think this might be reg / rectifier fault ???

Out on bike - 2 hour ride, bike suddenly looses all power, nothing on starter button, only light that works is neutral light.

Can't fix so get recovery out, bike starts with jump pack & revs, seems fine but soon as jump leads disconnected engine dies. Battery still showing as fully charged.

Any ideas / suggestions.

Thanks.

Battery was checked with multimeter when it broke down at the side of the road & was showing fully charged.

Sorry bit vague details, does anyone think it might be reg / rectifier ?

Thanks

Neutral light only item that works, suspect loom earth wire is no longer connected to chassis. Loom chassis earth lug located just forward of front ignition coil.

The source of so many posts on the forum ..the good old regulator/rectifier.
Sounds like the battery was overcharging as a result of the voltage not being regulated. If the voltage is higher than the 14.4v (roughly) that it usually receives at 4-5000 rpm then it fries everything unless caught early.Saw my own cdi unit generate smoke some years ago Need to check the pick up block connector for burnt out pins /melting and the ones on the regulator/rectifier and cut back to good wire,solder new connectors ,remake the block connectors and source a battery and decent regulator/rectifier before trying to restart your nc. I'm sure you'll get more posts on doing this .
Good luck.
