High beams issue!

I am using Mitchell the same as James ..so we are both giving you the same diagrams !!

These are the correct terminal number's ... is this what your relay looks like ?? the diagram is not an exact replica of the fusebox or how it is sat .. this could be causing the confusion !!.. on the wiring diagram the relay may be turned around and plugged in a different way ?? Use this diagram to check your PIN voltages please ?

OK and do the light's work in any ... especially the last test ??

Jumped #1&3 with H/L switch off #1 is 12 volts , #2 is 12 volts , #3 is 12 volts ,#4 is 0 volts .

Jumped #1&3 with H/L switch on #1 is 12 volts , #2 is 10 volts , #3 is 12 volts , #4 is 0 volts.

Not jumped H/L switch off #'s 1,2,3, are 12 volts , #4 is 0 volts .

Not jumped H/L switch on #'s 1&2 are 8 volts , #3 is 12 volts , #4 is 0 volts.

OK ground out #4 to chassis or a good ground point !..does anything work now, the light's should come on .. but with no switch control ??

You are saying "Not jumped H/L switch off #'s 1,2,3, are 12 volts , #4 is 0 volts" ... we should not have voltage @ #2 with switch off .. unless our diagram of the relay is also wrong like the wiring diagram ?

This is what we should have (not jumped) switch off

#1 12 volts
#2 0 volts
#3 12 volts
#4 0 volts

not jumpered switch on (if it is working)

#1 12 volts
#2 12 volts
#3 12 volts
#4 slight voltage increase

How are we getting power @ #2 with the switch off ??

OK jumper #3 to #2 with the light's switched ON

Take out the relay and check what voltage we have coming from battery to J/B .. 2 of the pins should have 12 volts and 2 should have 0 volts with relay removed !!

Also try jumpering #3 to #2 with the light's switched ON the light should work but not be able to be switched off !!

let me know

Sure .. I don't know if he is actually online in the forum at the moment as he has not answered a message I sent him earlier .. but i will forward your request to him .. no problem !!

Hey Mike.

I think James had family commitments yesterday, so let's try this .. the diagrams are showing the relay terminals but I want you to use the corresponding terminals on the JUNCTION BOX for the test's OK.

First check the R/H and L/H headlight fuse's and bulbs to make sure we have not blown them !

Do you have a test light ? if not, can you make one like this .. get a bulb from the car(flasher bulb) connect (solder)a red wire to the bottom pin of the bulb and (solder)a black wire to the metal surround at the bottom of the glass .. like this

OK ... remove the relay from J/B .. put the RED wire from test bulb into #1 JB terminal and the black wire from test bulb to battery or chassis ground .. the bulb should light up !

OK leave the RED wire in #1 and put the black test bulb wire to #4 JB terminal, the bulb should be OUT when you turn ON the light's at the switch the test bulb should come ON and go OFF when you turn the switch off ..if this is not happening we have a break in the RED/YELLOW wire from the H/L switch ..

Exactly the same results should happen if you move the RED test bulb wire to #3 terminal on JB and leave the black to #4 terminal on the JB ..

If the test bulb is working correctly... we have a break in the wire from #2 terminal on J/B to the headlight bulbs or the fuse's or headlight bulbs have blown !!

We can test this by checking the fuse's and bulbs .. are good ...the put the RED test bulb wire into the #2 terminal on J/B and putting the relay back in place (RED test bulb wire AND relay in the #2 terminal at the same time) put the black test bulb wire to battery or chassis ground and NO light should come on, untill you put the H/L switch to the ON position .. then the test bulb should LIGHT up and go off when you turn the H/L swith to the OFF position ...

Let me know

In answer to your question to James !!

I can see where your confusion is coming from ??

But does your relay BOTTOM look like this and are the terminals numbered on the relay ?? notice that the #1 and #2 pins are smaller and offset ??

OK we should have 2 hot's @ all time, one large terminal and one small !! using the test light I asked you to make ... put the black wire to battery or chassis ground point .. use the red wire to probe which 2 are HOT with the relay removed from the vehicle ... we should get one of the smaller terminals hot making the other smaller terminal #2 and we should get one of the large terminals hot making the other large terminal #4 do you agree !! even if we are not correct we can figure out which is #2 and #4 by putting in the relay after we know for sure which are the hot @ all times... remember remove the relay and test on the cars J/B, find me the 2 hots please mike and we will take it from there, once you have located 2 hots we will use the diagram on the last post marked with the 2 red crosses as both our references for terminal numbers OK .. sound good !!

Let me know

OK ...leave the relay out... using the test bulb ... put red wire to # 1 small terminal female connector on J/B .... and put test bulb black wire to the large female connector #4 on J/B ... turn onthe H/L switch ...this should light up the bulb .. if it does turn off the H/L switch ... the bulb should be out with H/L switch OFF

If you then swap RED test bulb wire to large female connector # 3 on J/B ...and leave the black test bulb wire to #4 female connector on J/B ... you should get the same result's ... test bulb on with H/L switch ON and test bulb OFF with H/L switch OFF ...
