headlight issue
#21
Can't get head lights to work!
I had these after market head lights in my truck and they worked but then I had no low beams I played with fuses and wiring and then I lost high beams, I thought it was head lights them selves so I bought new ones. Then I still have the same problem fuses are all good relay is good I hear it click. But nothing happens. How do I check for power at head lights? Where else do I check for power and how need truck on road asap!!! My truck is 1991 yota pickup sr5 3.0 v6

Well then check for power at the headlight relay and for good fuses:

The relay may be clicking but if the contacts are burned or pitted, it may not be sending power out to the lights.

You read 4Crawlers instructions how to check it?
And you searched for "Headlight Troubleshooting"?
A problem well-stated is a problem almost solved. Put us in front of that truck.
How do we know if you used GOOD after-market headlights? The headlight circuit is poorly-designed; even stock headlights strain the switch contacts; Some after-market headlights use higher power than stock/OEM so they could kill switch contacts even quicker.
And like Co says, go to HF and buy a multi-meter (pls see my signature).

Still
I still have nothing checked power and I have 12V on high beam with the volt meter and have 0V on low. But then when I plug them back in I have no highs even when I have volts going to the head lights. And of course no lows because I have 0V going to the lights.

A picture paints a thousand words. Exactly where are you checking power? Both bulbs will have 12 volts AT ALL TIMES when headlight switch is on. The dimmer switch selects which bulb to connect to ground.
Also, search headlight troubleshooting.

Ok I'll get a picture tomorrow but it is where the harness for the head lights plug into the factory wiring harness on the truck it's like three holes.

??? Sorry, English please.
I'll post exact test points tomorrow. Too cold to go out - LOL!

BTW... Many LED lights may not work with Toyota's switched ground headlight system. They are polarity sensitive. DOT-compliant but expensive Truck-lites would plug and play without modification.

Yes, you do have a choices:
1) Let someone else look at it, and possibly mess it up more, OR
2) Look at it yourself.
Disconnect those after-market lights. Check connector pins according to this:

(Go straight to alternative method - checking across connector pins)

Hmmm... 9003 bulbs? You mean you have conversion housing and not sealed beam?
Confused because you posted this on "84-85 Trucks & 4Runners"...
