Have my Oze gauges installed by my tuner when he was doing my Plazmaman install.

However the oil temp and pressure both flicker occassionally. Just often enough to be annoying. Mostly noticed when stationary. Boost is rock solid.

They did this before my oil plate arrived and I assumed it was because they wern't connected to the senders yet.

Enough power or an earth problem?

Am going to take it to an auto sparky for the fix. Just need a clue to give him.

Thanks.

could be an in-adequate earth, quite a few people have had an earth problem when using a sandwich plate

What do you mean they flicker...

Does the power go on and off or is the needle just flickering around?

Not sure how the sandwich plate would effect the earth at the earth is wired. It doesn't run through the sender body.

I remember a thread about this (I think it was by RUS531) and he figured out that the sandwich plate was not a good conductor so he ran a good size earth strap to it - no more problems. I'm not saying that this is the problem, but there is a good chance the earth has something to do with it

Ok.

I have these exact gauges and the earth is wired. It doesn't run though the sender, sandwich plate and engine.

Where have you sourced the power/earth for the gauges from?

Are the 3 gauges hooked up using the jumper looms?

turn the lights on and see if the light on the gauge flickers when the pointer on the gauge does, if so you have a bad earth for sure.

Does the boost gauge light flicker aswell?

Boost doesn't flicker.

The temp and press both flickered before the plate was installed.

No idea on connections sorry.

So what flickers exactly?

The lights.

Also the gauges are set to run blue all the time but when you turn the ignition they turn white except for the oil press which turns red.

Then start the engine and they all turn blue.

The red is a warning on them. You can adjust that.

Not sure about the flckerng
