Fitting HZ GTS Dash to WB Ute... Help Needed..

[wbute]

As long as its contacting the alloy dash frame it should be earthed. Sender is causing the gauge to go crazy. Fuel gauge should work if the old gauge worked? Same goes for temp.

[thatotherguy]

are the temp senders the same for a light and a gauge ?

Righto, I thought that about the earth... Yeah, I just hit me about the oil pressure sender.. Didn't even think about it before.. Umm, the temp guage worked but I have no idea if the fuel one works.. I have never had the tank full either.. may have to get a heap and fill her right up and see.. If it doesn't work after that, does it mean the fuel tank sender is stuffed???

I have no idea why the temp guage doesn't work.. I think if I can't get it to work, I'll bring in the auto electrician friends..

Umm, the original WB ones are guage any way..

Ohh, and how much does an oil pressure sender to suit a guage cost?? I got quoted $60 from repco up here and thought that it was a bit steep..

No, though in many cases the sensors will look the same or very very similar. The light is "switched" on by the temp switch earthing out and the guage is "sent" towards the high end of the scale by its sender allowing voltage to earth at a progressive rate as the temperature increases (by a change in resistance in relation to temperature of the sender unit).

Cool, thanks for the help mate.. You wouldn't have any pics of you dash when it was out by chance?? I was thinking that there may be some other earth that I have missed.. Hopefully I can get to it tomorrow arvo cause I have a free period at school last, so might sign out and come home and have a go at trying to fix it..

Its a pain in the arse isn't it.. lol I hate wiring, there is soooo much that can go wrong and it can happen when and where ever it like.. hahaha

Ohh, and repco didn't have a oil pressure sensor, so I have ordered one and its on its way..

You should have an earth on your column near the ignition switch (I think it might also join the harness earth coming from the combination switch out of the column) and another in the black harness coming out of the quad guages that as has been pointed-out should attach to the alloy frame. Dependant on what harness you're using/adapting you may have another one near the clock (not sure of the colour of the wire). Make sure you've got the main harness plug together properly..... Guilty of that one myself a few times in past years.

Thanks for the info on how the switche work.. I would never had any idea on how they worked.. lol haha

Now that you said that about the earths, I went and had a look at the pictures of the wiring harness that I took a while ago, I can see the two earths that you are describing.. One is in the part that goes to the clock and the other is on the next part of the harness that is separated.. lol

Its something as simple as that that brings alot of people unstuck.. lol Well, they say first hand experience is the best type of experience.. haha well I can tell you those will be the first things that I hook up tomorrow..

Thanks heaps [MENTION=816]Taily[/MENTION]; You've solved part of the problem..
