Hello. Welcome to Just Answer. Please allow me to assist you today. The first thing we need to do here is check the fuses under the hood. DO you happen to have a 12 volt DC testlight? That is the best way to check fuses
We need to look at two fuses under the hood, in the fuse box. You want to check the following:
HEAD LO LH and HEAD LO RH
If you do not have a testlight, just locate the fuses and remove them. Look at them closely and verify that the small piece of silver metal is intact between the two legs of the fuse, inside the plastic
i don't have a test light , but i can check the fuses
OK. Please check them for me.
fuses are intact
DO you have any means of measuring DC voltage? A volt-ohmmeter perhaps?
Can you obtain a 12 volt DC testlight form your local auto parts store? In order to properly diagnose this, we need to check to see if you have power in certain areas.
ok, i'll need a few minutes to go down the street and get one.
Excellent. You don't need to get a fancy one. A cheal 12 Volt DC light will be fine.
After you get the light, connect the clip to one side of the battery, (Neg) and touch the pointed end to the other battery terminal (POS) , this is to verify the lightbulb in the tester works.
After you verify that the bulb in the testlight is working (we need to know that first, so you do not waste your time with a dead bulb; happens)..........Attach the clip of the light to the NEGATIVE battery terminal, turn the headlamps on, low beam, and touch the pointed end to the head LO LH and the head LO RH fuses, both sides of each fuse. Pls advise if the testlight illuminates
Leave the fuses where they belone; no need to remove them
just checked the bulb in the tester and the rest of the chat was erased
what is next?
Hook the clip to the Negative battery post. Turn the headlamps on, low beam. Check the Head LO RH and the Head LO RH fuses by touching the pointed end t othe metal on top of the fuses, both sides. No need to remove the fuses.
nevermind, it's back
ok, both sides of both head lo rh and lh light up
That eliminates a lot of work.
Next, we need to look at power going to the headlamp belbs themselves. Please remove the wire connectors from both headlamp bulbs. We will be continuing this test with the headlamp lo beams on.
Remove the wire connectors, and check the Red with a Yellow tracer (on the LH headlight) and the Red with a Black tracer on the other side. Verify if the light illuminates or not.
After thsi test is performed, we will be checking the ground wires at each headlamp socket
ok, there is power going to those wires
Now. Remove the clip form the Negative battery post
Clip the clip to the Positive battery post
Touch the pointed end to the White with a Black tracer in both sockets, with the sockets unhooked form the bulbs
Advise if the light lights
they both light up as well
Ok. We have tested the entire circuit. We have power where it needs to be, and we have grounds where they need to be.
You have two burned out headlamp bulbs.
but i replaced them not too long ago, would something cause them to burn out so fast?
No shorts, no bad grounds, I am please to say.
Headlamp bulbs these days are pretty shabby when it comes to longevity. If you buy the "higher brilliance" (for lack of a better term), the light half-life is shortened pretty good.
The brighter the light, the less life it has. They burn up too fast.
Do you have any other questions fo rme today?
so the 'cheaper' the bulb the longer the life?
The "Less Brilliant" have longer life, but you sacrifice illuminating the road.
I appreciated your patience with me today. SOme of my clients get in too much of a hurry when we do this, and they get frustrated. Thanks
Is there anything else I can do for you today?
of course i know this isn't a simple procedure, it just seems that i've replaced both bulb 2 times in the last 18 months.
any other suggestions for longer bulb life?
That, to be honest, seems about normal these days.
No. Sorry. Unless your auto retailer can suggest "longer life bulbs". ....they might be addressing this issue.
thank you for the help, i actually learned a lot today.
nowadays nothing lasts like it should.
