i have a doubt of my v-tec is engaging correctly so i tried to hook up a bulb to see if it is ok but no success the bulb wont come on at any time and at any rpm even when it hits the rev limit at 9k. so then i wired up a little push button to the v-tec solenoid and the bulb lights up when i pushed it. i even noted that when revving up to 7k and up and the button is pressed you can hear the loud vtec crossover , something that i have never heard my engine do before. any ideas? does anyone know what voltage suppose to flow to the solenoid?
