New Alternator question

[Buzzard67]

Well the other day 3 dash lights turned on my Toyota Tercel DXL 84. Temp, battery and break light.
Was able to drive home and park it. Ordered alternator, installed alternator and new belt. Also noticed my positive battery clamp needed replacement so I did that as well.
Car started fine, ran fine, lights off. The next day started up fine but now only the brake light is on. Checked fluid reservoir, full. Pulled hand break and light gets brighter.
I believe everything is working well. ( wiper,lights, fan, radio) no drop in power or preforming with all accessories on. Just that dang break light is on. I know it mean something, I just don’t know why it started after sitting overnight.
Any help?
I did read the forum for similar topic’s.

Try disconnecting the wires going to the brake fluid level switch. Maybe the switch is stuck closed or shorted to ground.

I just tried disconnect the break wire that is located on the top of the break fluid reservoir and the break light remains on.
But I check the fuses under the hood and -#12 fuse ( alternator voltage regulator 15a is blown and replaced it twice. Blown both fuses.
So I don’t know what that means but I think I should return the new alternator and replace it.
Any recommendations?

Buzzard,

I would guess there is some wiring askew or possibly a bad alternator, but I would check wiring.
