heres my problem
car is an aw11 MR2
when i turn the lights on the lamps raise but theres no light, and the volt gauge hits 0 and the indicator dash lights both light up and the "lights left on" buzzer sounds. while the headlights are on (well switch to on) the indicators or hazards wont work. but when they are off they work, but some times super fast..... (theres no blown bulbs)
also when the indicators go into hyperdrive mode, the dash indicator flashs opposite of which way iv indicated. while this is happening all other lights (clock dash etc) all flash in time.... and the volt meter ticks in time. in fact when the hazzards are on the volt meter rapidly vibrates.
when i took a headlamp bulb out to see if i was getting power to the bulb, i found power at all 3 pins in the plug (h4 type bulb) hmmmmm
so i pulled the other plug off to check that one. that was fine... except only had power to one pin. when i rechecked the other plug, i found the same thing. only power to one pin as normal, but when i switch to highbeam its still only that same pin with power. yet with bulbs in, theres no light
so with one or both bulbs in i get power to all 3 pins on each plug (both bulbs work fine when plugged into battery) but when using a test light on the earth pin and a power pin, everything is fine.
im f**ked if i can figure it out HELP
cavalier with a similar problem. in the end it was a earth strap in the engine bay loose.... has the engine been removed recently or have you been steam cleaning the engine bay at all lately???
) but how can a bad earth result in power in the earth wire?
