91 FZR 600 Break Lights Stuck On

[Z3r0x7]

So I found out my battery was getting to much of a charge 17 volts. For some reason I decided to remove the battery to see if the stator would run the bike (I found out this is not a good idea). So it blew my headlights and from what I can tell, the break lights are stuck on with the ruining lights. I replaced the VR/RR and no longer overcharging and replaced the battery. I also replaced the headlight, that now works. The break lights, I've replaced but still they are stuck lighting both filaments. I've removed the rear break switch and the front break switch but the lights are still on. Next step is to check for a short or a misground. Is there any computer parts that I could have fried that would keep the break lights on? And how would I check for a short? Or what else do you think I should check?

Any advice would be awesome.

Bump.

There's nothing electronic that would affect the brake lights. If the brake lights are staying on with both switches physically disconnected, then you have a physical short somewhere. The first places to look are the switch connectors and the tail light sockets.

Don,
Thank you for the reply.
The switch connectors? are you talking about the wiring harness? Is there a way to test the tail light sockets? Or just eyeball them?

Don,
Thank you for the reply.

He means the plugs that connect to the brake switches, I would assume.

Also yes physically checkout the sockets for damage, burning melting, you might check the circuits (wires connecting from a to b) as well.

if you need some sockets, let me know, I might have some.

Thank you!
I found out the issue. It was the back break switch. I must have not disconnected it before.
But for shits I decided to check to make sure everything was charging and I'm now geting 12 volts and when I unplug the headlight fuse I'm around 13.8. From what I can tell the bike needs to be 14-15v. The replacement regulator was a cheep 22$ one. Think I need a new one? Also I checked the ac on the stator and at 3000k its geting around 40 volts. Is that to high?

40vac across each of all three legs is fine. 13.8vdc while charging a flat battery isn't great; see what it is with a freshly charged battery and the headlights on at 5k rpm.

I just replaced the battery. Its a sealed self contained battery, if that matters.

What's your voltage across the terminals with the bike off, key off?

12.1

[DonTZ125]

That's fairly discharged; should be around 12.8vdc. Do you have a charger, throw it on overnight?

Yeah, I can put it on. When I first got the battery it was charging at 14 volts and when I went to 3k it went down to like 13.8.

Not sure if that's the info you're tying to get at by me charging the battery.

Ok, I think I've lost track - let's back up a step. With the headlights on and the bike turning 5k, what is the voltage across the battery terminals?

13.3 with headlights on at at 5k. I did check the headlight and it's a 55/60 watt light. So tomorrow I'm going to go to the cycle shop and see if they have the correct headlight.

I wouldn't think it would make that big of a difference, even with a new headlight.
