My 90 vert's E-brake light doesn't work. I thought the bulb was bad but i tested it by moving the master cyl float to the bottom and light came on.. To test the e-brake sitch wire i shoud just ground out the wire right? Any more suggestions? Thanks

 

Correct.

 

Ok, that's wht i thought. I grounded out the wire and still no light on. Will look up to see where that wire runs
