Brake lever not signaling rear brake light. Found rectifier dangling :(

Guys,

I just realized that my brake light isnít getting brighter when I engage the brake lever but works fine when engaging rear brake. I then noticed the rectifier was dangling under the seat (did a relocation). From what I can tell all cables are intact. Apart from the plastic tray do I need to replace the rectifier to fix the brake issue?

Cheers,

Mike

That looks gnarly, how'd that happen?
Most likely you wont have to replace the R/R to get the brake light to work. First Id check the switch and then the brake light. Unless your R/R is fried there wouldn't be a reason to swap it out.

I have no idea how it happened and I honestly donít know how long itís been like that. Not too long I think.

From what I can tell the switch is going up and down as it should.

The brake light is working as it should when I use the rear brake (gets brighter when itís pressed).

Iím going to order s replacement tray but Iím at a loss for why the lever isnít making the light go on.

i would expect it's a bad front brake switch. if not that, bad connection.

You might want to look into replacing your rectifier with a Mosfet unit. I wonder if its been heating up the plastic over time to where it just became so brittle it cracked.
