NC30 Ignition Problem

[vfrman]

You might be right.

Over voltage could be three things. Poorly grounded reg/rec, bad battery, or bad reg/rec.

The Haynes manual is kind of sketchy, but the Honda NC30 service manual is better.

To inspect the regulator check the following..
There should be voltage (like 12ish) between the red/white and ground.
There should be continuity between green and ground.
There should be between 0.1 and 1.0 ohm resistance between all yellow wires.

If any are weird, replace the regulator.

Thanks for the advice chaps. I'm unfortunately mechanical and not electrical minded so a couple of questions.

1 what do I need to set my meter to for checking continuity
2 how should the reg rec be grounded/earthed?

yes its knackered mate voltage from battery when bike running should be between 13.5 and 15 volts max. you prob need a new rr and battery now.

And definitly check the genny too. Dont want to have melted something in there and have to replace it all again like someone i know ... (ok it was me)

1. There should be an ohm setting on the meter, and some of them have an alarm that will sound when there continuity. If you set it to ohm, there should be some sort of reading when you check the wires. If it doesn't register anything, then there is no continuity.

2. The reg/rec is grounded by the green wire coming from the connector. It wouldn't be a bad idea to check all of your grounds, the battery negative cable being the biggest one.

And as suggested, check the wiring from the generator, they are the three yellow wires. If you have to replace wiring, don't worry about which yellow wire goes where, as long as they all go to the same connection as the original three yellow wires. There is no order, in other words.
