    My headlight switch burnt while reving...

    All,

    My headlight switch melt suddenly while I was driving - I replaced it with a brand new one - on idle the headlights were on and no smell, then while reving smell of burn again....
    I wondered if a faulty regulator would cause this.
    I checked the battery charge at idle and 1500rpm, battery charge seems ok (nearly 15v - it is a 3.2 alternator)
    Checked the fuse panel, ok
    I noticed there is no relay.

    Any one faced this ?

    Cheers

    Anything over 14v starts getting dicey.

    90amp alternators have internal regulators. Try that right after you check all of your connections.

    H4s need a relay(s) or they will fry your H/L switch. The wiring gets too hot. Ask me how I know...
    I installed this kit:

    That fixes the problem. Too bad that relays are "not correct" on these cars...
