Hey Guys,

Hope its ok to post in this part of the forum?

I have a few issues with my datsun lighting.

Left indicator dash light will not work, due to tight behind the dash I cannot feel any fittings for bulbs? Is it a bulb behind the dash to come on when turning left indicator on?

SOrry I have tried the Tech Wiki, I am sure the answer is there but I havent had luck, I may not be looking in the correct spot.

Any help would be highly appreciated.

Thankyou Guys!

Yes it's OK

Left indicator dash light is just to left of speedometer



It is tricky to reach. Basically it's at the very top and pushes in/snaps out

See those two holes? Deep past the back of the gauges



It is more straightforward to remove the cluster, but that takes a while
otherwise it is possible to reach up and gently rock/pull the lamp out

Once the lamp socket pops out of the hole, you can push the bulb in and twist to remove it from the socket

Thanks Mate.

Got to it, changed the bulb with a new one, still doesnt work.

Seems like it is a wiring issue.........

Probably best to remove the cluster so it can be examined closly

You see that socket has only one wire? The bulb is earthed via contact with the cluster metal body. Maybe the socket is slightly corroded? or maybe the spade connector is corroded? A pencil eraser will clean up the brass coating. The bottom contact is some kind of lead, and can be scraped clean with a screwdriver tip

Thanks Mate.

Will give that a go afterwork tomorrow.

Thanks Mate

Got all the dash lighting sorted!!

Wining!!

Now, weird issues.....

Sometimes the head lights will work in low beam, sometimes only highbeam the right hand one,

Wipers wont work, washer bottle wont work, horn wont work>>>>

I have tested each item with full power from battery and they all work fine no dramas, its when I pull the switch to operate them from the dash they wont work........

I connected up the from indicators the go under the front bumper bar and the flashing was very slow but can hear 2 clicks per flash when operating. Normally one click per flash. Really Weird!!

I am thinking have I got a bad Earth??

Or is it likely I have broken wiring in the harnnes?

All the fuses are ok and not blown, connections look clean, but thinking I probably should stick some emry paper an clean it just in case?

When that kind of thing happens I tend to suspect the grounding wires.

First make sure these wires are connected well, if the connectors are rusty, sand them to bright metal

Ground/Earth main connections



Make sure they cables are not damaged, and that they are securely fastened. If they are loose, remove and carefully inspect for corrosion. Clean thoroughly if possible, replace if necessary.

Thanks Mate

Unfortunatley its not the case.

I have cleaned the earth wires and where it bolts to the chassis, new bolt also installed. All bright and shiny.

Done a clean, spray contact cleaner in some of the connections to the horn, washer and wiper.

Along the way when i was moving wiring to clean, the lights were flickering.

I suspect i have a dodgy wiring harness.

I also noticed the wiper motor was warm when checking the connections.

I will have to go over it all with a test light and see if it is the harness.

Fingers crossed it isnt as its no fun job swapping the harness etc out of the dash when i have just had the dash out and put all new bulbs in.....

A new used dash wiring harness is not very to find.

I have a spare if you get stuck, and i am sure plenty others here do too.

Wiring is always a pain, even on our simple Datsuns

Dogdy harness?

Replace it IF
* Cut/hacked/spliced
* Burnt/melted
* Physically damaged

Otherwise a harness just needs a good cleaning. Clean the connector terminals. Spray with De-oxit
