Hilux / KC Daylighter Problem
I know its not seven related, but auto electrics all the same. I have a '97 Toyota Hilux pickup, and have recently wired a set of daylighters
up. I wired them correctly, tapping into the main beam feed on the lights. Without the engine running, the lights are perfect, coming on with main
beam.
However, with the engine running, the lights also come on with the side lights. I guess this is due to the alternator supplying over 5 volts,
switching the relay over. Would I able to put a resistor inline with the main beam feed to knock the voltage down, or is there any other way of
sorting the side light problem? Would another relay somehow linked in solve it?
Thanks in advance,
Matt

It sounds more like you have selected the wrong wire to the main beam?
Try a test meter on the wires directly at your headlight and take your relay feed from there.

I agree - the sidelights will probably be on the wrong side of a relay. Time to get your meter out I reckon

Hi both, thanks for the replies. The feed is taken directly from the headlamp; The tricky part is that I think toyota use some negative grounding
system, but I've had a look with the meter, as I used it to wire them, but the problem only occurs when the engine is running. I'll have
to go back and double check everything now I've had a break!

That doesn't make any sense to me - Negative ground is standard on most cars so that's not the problem. If you have picked up a 12V feed
to trigger the spots' relay, then the relay must be incorrectly wired somehow. Where are you getting the main feed from? Direct from the battery
of from the fusebox? Possible you've picked up a sidelight feed there?

you do have to wire the spotlamps differentley on most jap 4x4's i have a wiring diagram for the relay at work i'll sort it out tomorrow
but you would need to pull power from 2 points on rar of lamps

Yep the last Diahatsu jeep I did had a 12v live at the light (where the neg would usually be) and two switched negatives for the lights to come on.
If it looks wrong it probably is wrong.

switched neg that's what I meant sorry Raz!! If you could get that wiring diagram for me andybod it would be very useful to have something as a
point of reference.
Thanks again all,
Matt

Yeah, loads of Jap stuff is switched on the negative side. Fooled me for a while 10 years ago on an old Subaru I had that the headlights kept coming
on on their own!
Could it be there's a Dim-Dip relay involved somewhere? They put dip beam on but only on a dim setting when you drive with the sidelights on.
