RT3 headlight.

The RT3 being a 6 volt system, does the engine need to be running for the headlight to funtion?

Yes, it does.

Thanks, great news. That means I have all the electrics sorted out finally. What a process. I couldn't check the light myself due to the bike still on the lift and I'm putting it all back together or I would have just started it and checked myself. Asking you guys was just a faster way to ease my mind.

Time to find and buy another old Yamaha and get it going. This hobby is very addictive. Thanks again.

Have I mentioned voltage regulators yet?!

I have attached a link below to Yamaha's own Service Bulletin on it.

Some people swear by sticking a 12v bulb in the headlight. However, if you're still running the sealed beam (which you can test by connecting it direct to a 6v battery), then that isn't an option for you at the moment.

What are you looking for? I have some for sale.

The bike has a sealed beam, I suspect that's stock for this bike and it is working. Would this be a good way to stay for now? I won't be driving at night anyway.

I want to stay with enduros due to the fact that I can use them on the street as well as trails. Nothing smaller than a 250 and preferably Yamaha due to the help in this forum and parts availability. I have this RT now, probably a DT series for a change, mid to late seventies, 175cc and up. It would depend on where you are. I'm on Vancouver island in British Columbia.

I'd go with fitting a regulator then.

So you've waved farewell to our royal resident then?!

Got your message about getting a regulator. If my sealed beam is working now, why would you suggest a regulator? I suspect, like our other messages on my bike's issues that you have helped me with fixing, you must have a good reason for this. Sounds like it would be in my interest to hear it. Thanks.
