The hi beams will not come on when I turn the headlights on only low beams come on.

That's OK, I just got my first grandaughter last April. They're pretty precious.
We're back on track. Now, with HLSw on and you " ground" term #4 do the lights come on? If yes, with #4 ground removed, do you have?
Low beams Yes/no
High beams Yes/no
High beam flash Yes/no
Let me know. I sure hope the car is close, or your putting on a few miles.

What I don't understand is with the relay in and the hlswitch on why do I get an 8 volt reading on legs 3& 4

In an earlier reply you said that #13 wire from the switch was the ground for leg #4. If thats so then shouldn't I be able to splice into #13 and run a jumper to leg # 4 and see if I get any lights? If I don't get any lights then there must also be a hot wire that I can also jumper to the #3 leg. What do you think?

I tell ya' what. If you don't mind, if you'll give me your phone #, I'd be more than happy to give you a call. I don't mind, I have free long distance. The only thing is you'd have to have access to the car, a phone and light at the same time.
What part of the world do you call home?
To make your voltage tests, are you using a testlight or a meter.
The biggest problem most people have with automotive wiring is that everything is backwards from the wiring, like, in your house. I'm an electrician by trade retired, and I still sometimes have trouble with auto circuits. Let me know.

I checked each socket before putting in the relay.With switch off 1&3 showed 12 volts 2&4 showed 0 volts. with switch on 1&3 showed 12 volts 2 showed 0 volts and 4 showed 8 volts. After putting in the relay with switch off leg 1 showed 12 volts legs 2,3&4 showed 0 volts. With switch on leg 1 showed 12 volts leg 2 showed 0 volts legs 3&4 each showed 8 volts. Then with switch on and relay installed I grounded #4 leg and nothing happened so I put 12 volts to #3 with #4 still grounded and the relay worked and the lights came on. Hope you're good at puzzles (ha ha)

Hope you don't mind me adding 2 pence worth !!

If you are getting HOT @ #1 & #3 before you install the relay into JB .. but no HOT to #3 after relay is installed ... the problem must be under the JB on the wiring connector to #3 ?? especially when you then added 12 volts to #3 and everything worked !! #3 should be a HOT 12volts at all times as james has previuosy stated ... so i do not understand where the 8volts is coming from @ relay IN and switch ON ...also how did #4 show 8volts with switch on but no relay installed ?? hope this helps

Hi James & Dave: James, my name is Mike my ph.# Is 361-578-6705 and I live in Victoria Tx. Also I'm using a meter to do my checks and I have the car sitting in my driveway. Dave. As to your comment, I do appreciate any input I can get, thanks. You're right about the #4 leg, I don't understand why it has 8 volts either, at anytime. I would think it would have 0 volts or if it were shorted to another wire 12 volts. Thats why I was thinkig that if I jumpered 3& 4 legs directly from the wiring harness on the steering column to the relay and if the lights came on and were able to be controlled by the switch then that would show a break in the circuit from the junction box to the switch. Does that make sense?

Hey Mike.

Put the relay in and with the top off check #3 it should have 12volts ... if it does not, add 12 volts to it and test the switch ..it should work correctly .. if it does then the problem must be below the JB ...on the 12volts supply terminal or wire ? let me know

Hi Dave: Guess what? I installed the relay and checked the voltage and it showed a varity of readings depending on where I put pressure on the #3 leg it went from 12 to 0 volts. When I got a 12 volt reading I turned the switch on and got no lights but when I engaged the hi beams with the dimmer switch they came on. So I put the new relay in and tried it and got no lights and the dimmer didn't work either. So I think you're right. I think there is a problem in the junction box. So I'm going to take it apart and see what I can find. I'll let you know what I find. How does that sound?

Hey Mike.

Sounds good to me ...I think you will find a bad connection on the #3 pin underneath the JB .. let us know !!
