2009 Burgman 650. The right brake light and right rear turn signal don’t work and I’m not sure why.

Both bulbs are good.
Checked the fuse panel and don’t see any fuses that are blown.
Both brake levers work and activate the left brake light.
Both front turn signals work. The right one blinks fast (of course) since its the only one getting power when activated.

My question is what would cause both of them to be out? Could it be the turn signal relay next to the fuses? I’m not too familiar with electricals or the Burgman’s writing harness in general so any suggestions would be much appreciated.

Seem to remember that I had this problem many years ago and it transpired that there's a plug buried under the battery that had somehow become disconnected. Memory a bit hazy; as I said, it was a long time ago.

There is a connector under the rear cover that is known to corrode pull the cover off and give it a once over.

Thank you! I’ll check that area out.

I gave a light once over when I checked the bulbs but my next that was to go through and look at it all in greater detail. I’ll keep an eye out for the connector. Thank you!

My experience with several vehicles is that a ground wire has disconnected. Check that there is power to the bulb socket by using a known good ground connection, then find where the disconnect is. It often involves corrosion. Hope this makes sense; I'm just blurting it out as I try to get back to work.

That definitely makes sense I hadn’t thought to try that. I’ll definitely give it a go. Thank you!

Your best friend when doing electrical troubleshooting. Clamp on the battery Neg lug and then use the sharp point to probe connectors. You are looking for power this way. To look for bad grounds see next post below.

Then to check for bad grounds, clamp on to the PoS lug and probe ground connectors.
