Rear blinkers go nuts when I turn my lights on ?

[kenny000]

Hi all,

 

My blinkers work fine when I use them without my headlights on. When i turn my headlights on both the rears blinkers turn on, so do the brake lights and well all the lights are flashing, like its a disco back there (fronts are working as normal. What sort of troubleshooting do you guys suggest to weed out the problem ?

 

 

Thanks in advance

Negative earth problem somwhere under the dash?!?!?

Yeah sounds likely to me. Go through the loom and clean all earth points onto the body, there'll be 30+yrs of corrosion under them. Just a light rub with emery paper or sand paper should do the trick.

+1 for earth connections.  On old alfas, its always at the rear light itself - 105s the wire corrodes off the bulb holder, on alfettas they have a stupid circuit board thing which the bulb holder stops making proper contact to.

Common mistake I've seen done is a single filament globe installed in a twin filament holder; has anyone changed globes recently? When you park lights are turned on and a single filament globe contact bridges a twin contact and feeds power to a circuit that hasn't been switched on yet....

Dimetris on it ,, i had a similar problem replaced all the globes , several stop globes were shoting out on the filiment sending power back up the loom , ive had a lot of problems with cheap globes blowing and shorting out , insist on phillips and replace them all
