Fitted marks quad gauge today, when turning ignition on the temp gauge goes straight to max, checked the sender wire and that's ok. What do I check next?

Start wiith the wire on the back of the guage. See if it is grounded from there. (probably is) Find a ground somewhere between guage and sending unit.

Sounds like the wire from the sender to gauge is grounded somewhere. |

or one of the (+) wires is touching the gauge at the sender feed |

Check the sender wire for grounding. Check
check the wiring at the gauge. Check no probs there, what next? (IMG:style_emoticons/default/smile.gif) |

Did you check the sender wire all the way from the sender to gauge???
Maybe something inside the sender is shorted??? |

Do the gauges not fail? It's 100% a wiring problem then?

If the gauge combo you got was new, then I'd not think the guage is faulty. I still think there is some wiring problem.....

Check the resistance of the sender .... If it is 0, the guage will peg. The guage reads resistance ... the sender is variable resistance according to temperature.
That said, if it pegs on the turn of the key, generally, as others have said, the wire from the sender is fully grounded somewhere. And make sure you have the wires connected correctly ... "G" is guage, not ground. |

If you disconnect the wire from the sending unit, the gauge should read cold. this will give you some indication if your gauge is working.
Also, if you have a potentiometer laying around, connect this between the gauge and ground and twist the pot. At some point, the gauge will go from cold to hot if it's working correctly. |

UPDATE -
On the back of the gauge there are two wires + and S. Am I right in thinking that + is +12 and S is sender?? If so....... as soon as I connect the +12v to + the gauge goes straight to MAX. Even if the sender wire is disconnected. |

what about ground? Is there a connection for that anywhere that you see?

I got marks Pre-wired gauge and the fuel and volt gauge work perfectly, so surely it's grounded on the pre wired loom along with the other gauges.. Seems weird that as soon as it's given +12 it goes straight to max (IMG:style_emoticons/default/idea.gif) |

I'm having the same type problem with my fuel gauge. As soon as the key is turned on it goes straight to full. It's with my Fuel Safe fuel cell sender and gauge. I haven't had time to dive into it yet.

On my single center console temp guage, I had failed to ground it properly and the result was to peg the gauge at hot after about a minute of running, I guess oil temp was just beginning to actuate the sender and as soon as it connected at all (the sender is a variable ground), the needle pegged.
I think it has to be the grounding... |

Been chatting to Mark via email and he thinks the gauge may be too tight in the housing, so we are backing it off to see if it's grounding internally.. |
