Hi all,got another electrical question,problems while refitting all my cars lights,indicators.
I cannot remember which wires plugged where,on the rear loom going to lights,indys,fog light.The wiring in the boot was a bit wrong to start with, from previous owner converting from brake,indy,reverse lights,to the mk2 lights of no reverse light.I seem to have what seems like wrong coloured wires,and maybe a few extra,that do not seem to connect anywhere?

I have connected the 2 loom plugs to each light,so surely there not wrong,as there only one way fit.Now the lights are just placed on parcel shelf at the moment, while I try and get them working.My tail lights are working,but when I press the brakes the stop lights are not working and if I switch indicator on the tail lights flash, not indicators?
If I switch hazards on,the indicators all flash,but there is slight current/light on the tail light bulb?

Sorry for long post,but before stripping car down,they all seemed to work ok! can a bad earth cause this...its a 1991 4 way fusebox, with 2 pin hazard,3 pin flasher if it helps.Been trying most of the night to sort it, with no luck.
Thanks in advance.

The extra wires seem to be twin black wires each side at rear and 1 each side with blue/yellow? I cannot find blue/yellow in my haynes diagrams

Yes, if there's no earth connection the current will back up another earth wire if it finds a path via another earthing point. If that's via a higher resistance it'll limit the current at the indicator (that's now wired in series) and it might not light up even though there's enough current to heat the tail light bulb to a glow.

Hi, all sorted now I hope after messing for hours I put a jump lead to all the earth wires and clamped other end on a earth point, and all worked as they are suppose to. Earths causing all that...I know for future problems now.Cheers again.Olly

I thought it was all sorted, but now either after wiring up the rear lights or changing my fuse box, i am now NOT getting just the front sidelight on its own.
The 1st click on light switch is bringing the side and dipped on, and 2nd click still the same.For some reason, which is now blowing my mind, i cannot think whats causing this? Any help please, and thanks in advance.Olly

Is the ignition on when you try this?

[olly33]

Hi,
No ignition off.It seemed fine before even with ignition off,either fitting rear lights or since I changed from a blade fusebox back to standard glass fuses.

Give the big pink relay under the dash a smack.

Hi,I have been messing under the dash, but also i used a feed off the lights to power the foglight, and now i have disconnect this wire everything seems ok again.Not sure if the pink relay was knocked or because the wire i disconnected. Cheers
