Hello fellow Noble owners

Can you help on the below

I am changing out my gauge lights to LED (Speedo light was out). What a total PITA. Unfortunately I am not a hobbit from the shire with tiny hands.

Anyway I have changed out the water gauge with great success. However i have changed the bulb to LED on the oil pressure/temperature gauge but i still get hardly any light coming through see pic. I was going to disconnect the gauge and open it up, but it has this strange connection on the back that i am not sure how to remove and i dont want to mess it up.

Any idea on how to remove this connection, it looks like the metal sleeve is crimped on?

Has anyone done this before or had the same problem with a gauge light not showing not showing

Also on oil temperature what temp does your oil sit at?

I'm sorry, I can't help with this but can I ask if you just brought 12v LEDs and did a straight swap as I intend to do mine soon.

Thanks

The oil temperature sender signal can't be disconnected at the gauge, it goes all the way down to the sump!

LEDs only shine straight ahead whereas bulbs spread the light.

LED's are specified by luminescence, colour and viewing angle.

Yes but compared to bulbs they shine forward only, I gave a simplistic answer to the OP to answer his question.
I deal with cluster illumination as part of my job and getting linear light spread across the gauges isn't as easy at it might look, LEDs and bulbs require different solutions generally.

Depends how hard I'm driving but between 70 and 100 deg c

Don't try to remove the connection at the gauge.
The temperature sensor is a sealed tube that is piped to the gauge and is not removable from the gauge.
To remove the gauge you need to remove the sensor tube from the oil pan and pull the whole length of tubing and sensor out of the dash.
The whole thing is sealed and there is no electricity involved.
The oil in the pan heats up the liquid in the sensor tube which expands and causes a pressure rise in the Bourbon tube in the gauge.
The bourbon tube tries to straighten out and this makes the indicator needle to move.

Does the sensor have to go into the sump? Is there not a more appropriate place to have it?

Can the gauge tube be replaced if it gets damaged or do you need to buy a whole new gauge?

Surely that is what light guides and pipes are for, I can't say on here but I play with LED's for some well known car manufacturers,

OP your biggest problem trying to retrofit LED's into the gauges is heat, I played with them a few times without much success,To look good the best way would be to have a separate circuit for the gauge lights, using a constant current driver, then you could dim them properly.

Thanks for all the comments and advice folks.

Ok I will maybe need to live with this as I am not going to disconnect the whole thing.

I should of mentioned before that the gauge light with the normal bulbs provided worse lighting on this one gauge.

In regards to temp recently mine is hardly moving up when driving. Sits about 50C. I dont remember it being that low before. I did recently do an oil change. Any ideas on why it would be so low? I put in 5w 20 as mentioned in the manual. i believe it was 5w 40 before

To mgbonds question

Yes I bought 12v led from superbrightleds.com

They are plug in play. On all gauges they made a big difference apart from the one oil temp gauge

Drop me a message if you need anymore info

All of mine are led, I Colour Matched some
Blue ones I bought on eBay then soldered them into the correct bases, one thing you end up seeing is the different construction of the gauges, the speedo and rev counter look slightly different, so do the booth and oil pressure,

I now have boost and oil gauges from SPA so can have a few different colours. Wanted to change the dash one to blue to see how that works with the SPA gauges in blue mode

Thanks for info.

What oil is everyone using?

This was Copy and pasted right from the manual.

Engine oil: First oil change after engine install at 500 –1000 miles. Use a 5w-30 mineral based oil for at least the first 3000 miles. Use a SAE 5w-20 synthetic like Mobile 1 after this. Change oil every 3000-5000 miles. More often under sever driving conditions. See engine manufacture for specific recommendations.
Capacity: Stock Pan - 5 quarts
Track Sump Pan – 7-8 quarts

My book says shell helix ultra 5w40.
20 would be way to thin!
