Well I tried a new relay and thet didn't fix the problem. I'm really puzzled now and don't know where to look to fix it. Any suggestions?

Do the high beams come on when you hit the flash switch?

No. The only thing that works off the switch is the tailights and the signal lights. Could there be a fusable link or a fuse I'm missing? What about the integration relay?

Well, according to the diagram, if the " integration relay" was bad, you wouldn't have any headlights at all. Also, I'm not sure we're talking about the same switch judging from your last post. With headlight low beams on, if you pull up on the turn signal lever do the high beams come on momentarily? The low and high beams are on the same 2 fuses.

Hi James: What I meant to say was that normally the switch works the headlights but at the present time it won't turn the headlights on it will only turn on the tailights and siignals. Since I last talked to you I took the top cover off the old relay and installed it in without the top and then jumpered the relay coil wires so that power would go thru the coil and energise it. When I did this the lights came on and the switch could be used to go from low to high beams and flash on high beams. The only thing I couldn't turn the lights off without disconnecting the jumpers. So it seems that I'm not getting any power to my relay. Are the lights tied into the ignition switch in any way?

Ya' done good. Pulling the cap off the relay and physically cosing it is an old Jaguar trick. Most people would think of it, but I do it all the time. Looking at the diagram, terninals 1 & 3 on the headlight relay socket should be hot at all times. Terminal 1 must be or you wouldn't have gotten any headlights. Then, with the headlight sw. On, check term 4 for ground. If no ground, ground the #4 terminal, if the relay is good, the headlights should come on. The ground comes from the headlight switch (HS) through the integration relay. Ihave checked everything I have and can't find a breakdown or purpose for this relay. It must control other functions, but I can't tell you what. But, if you have ground coming from terminal #13 of the HS, it has to be a problem with this relay. Now that I know that you had no head lights at all, we're getting close.

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)

Unless my diagram is wrong, everything was checking out good until you put the relay back in, with relay #4 grounded and had to supply 12 volts to term #3 to close the relay. #3 & #1 should be hot " all" the time reguardless if the relay is in or out. Or if HLSw is on or off. With relay in, HLSw on, would you check voltage at term #3 one more time? I'll wait for your response.

Sorry James I had to pick up my grandsons. When I put the relay in and turned the switch on the #3 leg reads 8 volts
