A couple of months ago I finally got the Jag back up and running after about 3 years of work. Since the weather has been decent I took it out for a test run and all is running great. But, when I turn on my headlights, the turn signals/indicators don't work as does the 4 way flashers. with the headlights off they work fine, which is not too much of a problem since I only really use it during the day, but there is always that change of some night driving. Another weird thing, with headlamps on, push the hazard switch on and the computer flashes

things I plan on checking,

1) recheck the grounds that where undone during my adventure, as well as others.

2) check the 4 way hazard switch as it may have gotten some corrosion during the long time sitting

3) check headlamp switch for corrosion that may possibly built there during the sitting time.

4) recheck wiring portion for the front lights as that is where all the work has been done

So, guess trace, trace and trace to find the culprit/gremlin

any other ideas will be appreciated

 

Alcohol, lots of it.

Other than that I am on the same page.

 

I intend to have my favorite water with me, It's called Stoly

 

+1 on the alcohol, we'll all have a drink for you.

Fuse no5 and the terminal post are the only things I can see that are common to head lamps and indicators.

The only thing I can think of ATM is a bad earth or corrosion/bad connection in the indicator wiring. My guess would be either, the flasher unit, hazard switch or the indicator stalk.

If there is a bad connection (ie high resistance) it will cause a voltage drop, reducing the current available for the indicators, turning the head lamps on will reduce the voltage again and prevent the flasher unit operating.

 

Well from what I read I am on the right track, Thanks guys

 

Twelve cylinders scotch with me.

 

I thought the ROM specified brown liquors. Hey, it's your car!

 

 

Well solved the issue or mystery with the turn signals/flashers. to be honest not sure how, removed the headlight relay to clean the connectors, and ordered a new one in case, anyhow, not sure if accidentally dropping it, or the cleaning did the trick, but turn signals/flashers work now with headlights on. only a new thing popped up, the side marker light on the drivers side flashes when the left turn signal is turn on as and does not light when park/driving light are on, right is fine with park or headlights are on, but goes out when the left turn signal to turn on, DAM That Lucas, if it were possible to meet, I would pull his head out of his *** LOL
