Dudes,

I've stripped and cleaned the corrosion of my MC28 I imported from Japan earlier this year.

So I've put it back together again and now when I put the card in the indicators at the front of the bike are on all the time. Apart from when I switch the indicator switch to the left or right, then they flash properly.
The headlights, that worked a week ago now doesn't.
Weirdly, when I opened the neat little black box with all the connections that sits under the tank near the headstock, I pulled the horn plug out and the indicators worked properly.

I did the usual of making sure the headlight bulbs are working, I put a new and charged battery on the bike, checked the connectors which all seem fine.

I suspect it could be the handlebar switch unit on the left handlebar being corroded. When I push in the hazards button it's really slow to pop back out again.
The horn works.
All the connectors seem to be connected properly.
I checked the fuses which are fine
I sprayed WD40 into the switch unit but it didn't make any difference.

A chap at work suggested it could be a bad earth from the horn.

And that's everything I know.
Is there anything i should test or check?
I've got a multimeter and I'm ok ish doing electrics.
Any help would be greatly appreciated.

Cheers,

Rich

I think you'll find the indicators staying on issue is how they are in Japan, mine were the same. One of the three connections to each indicator needs disconnecting.
The headlight? Can't help you there I'm afraid.

Hi

I had the same exact problems with my indicators and headlamp as I am rebuilding mine too.
As said by eggsy01, you will have to unplug one of the wires because otherwise they will stay on. I believe there are three wires but you just need two.

Try to give the kickstart a few kicks. My headlamps went on after the third kick.
I have no idea why because I had a fully charged new battery too.
I even bought new headlamps which are extremly expensive.

Hey thanks guys, unplugging the third wire to the indicators worked a treat.
I'll fire the bike up tomorrow to see if the headlights work. Hopefully it doesn't fail the MOT if it's a requirement for the headlight to work if the bike isn't started.

If I don't oversleep I may be able to get the bike in for MOT tomorrow.

Cheers

Rich
