no burn marks that I saw, I even took it out of the housing. Prior to this the lights would not come on (intermittently) then after a few minutes they would pop on and you would hear a click or ping sound from under the dash. I know used electrical parts are a crap shoot but for 10 bucks it was worth a shot

get another one, for 10
Make sure battery holding 12 volts and Alternator charging 14 volts when running, also while watching Altenator reading rev it up dies charge stays at 14 or drops
Please let me know
