Pull the head light switch and use a 12 volt test light ($5-$6 any parts store) to see which wire dims the test light when u turn the dash light dimmer up and down, that is the wire you need to tap into for guage illumination.

Nissan Navara won't start , not getting any ignition lights , no headlights nor door locks , the house lights work alone ... the battery is good . Was driving and the van just cut off ..

you blew a fuse link at the battery wire.
It is a lower gauge wire say a 10 gauge in the normal 18 gauge wire. If you get an over load the 10 gauge wire melts breaks the circuit to protect the system.
Wire in a new fuse link from parts store. When you P/U part they can tell you exact location of fuse link on wire. It's EZ
to wire and EZ to find it will look all melted for about 8 inch.
Hope this helps Mike

Dodge Neon low oil pressure

Hi John, Im AL the owner of Big As Auto Repair.

John, Low oil pressure can be many things. BUT, first you need to hook up an oil pressure gauge just to make sure its not the oil pressure sensor. If you have already put a new sensor on and it still has low oil pressure then you still need to check pressure with a gauge to make sure its not in the wiring or connector. If you find good oil pressure with the gauge then it need to be check to see why the pressure is low. It could be oil pump OR bearing issue. Hope this helps and please visit my auto-repair-website here:

Headlights and driving lights do not work what might be the proublem?

First, check for output voltage at the headlight switch when the switch is turned on. If you do not get output voltage at the switch, replace the switch, and you'll be good. Otherwise, read on.
A common problem with those GMC and Chevy trucks is that they used too small of a gauge for the headlight wiring under the dashboard. You will need to use a voltmeter to check all points of the headlight wiring from the switch to the headlights to determine where the voltage is lost, and will very likely need to replace some wiring. PLEASE BE SURE YOU USE HEAVIER GAUGE WIRE THAN WAS USED BY THE FACTORY, so that you can avoid having to re-do the work in the future.

What would cause the headlight switch connector to melt down?

Connectors melt when the wiring is of too small gauge to handle the amperage required, and the copper becomes overheated and burns. Replace any wiring or connectors that appear... crispy with wiring of a slightly larger gauge, and replace any connectors that appear, even slightly, burned.

My head light switch caught fire and i now have to stick the three wires to get them to come on and they get real hot after about 5 mins and i cant go far because i dont want to burn the wires out how can...

Make sure you disconnect the battery, before you start this project. There's power at the headlight switch all the while that the battery is connected.
It gets hot because it's overloaded (a short somewhere) or there is a poor connection. I would suggest going to and see if any local salvage yards have a good switch. You should get the plug, that goes on the switch too, with as much wire as you can get from the junk car and splice it into your wire harness. Solder and tape the connections between the new and old wires if possible, otherwise you can buy crimp style "**** Connectors" from an auto parts store. You will have to but the crimp tool to use the **** connetors, make sure you use the right size connector for the wire. Yellow is for 10-12 gauge wire, Blue is for 14-16 gauge wire, and Red is for 18-20 gauge wire. You will have to get some of each color because of all the differant size wires.

Need to attach new electric temp. switch/sensor where aftermarket mechanical one is installed

The factory wire to the factory gauge is a solid green wire. that year truck the sending unit usually mounted in the drivers side cylinder head but i have seen some in the passanger side if they have cut the wire and you can goto the main harness connector under the brake master cylinder and booster and find the only solid dark green wire and follow it forward to see how far it back they cut then just splice and run it to your new sending unit . If you want to check to make sure the gauge works after you find the solid green wire put it to a ground and the gauge should go to hot if it does not you have a bad gauge or a cluster wireing in side the truck and that is why they put the aftermarket gauge in .

96 honda civic lxi overheating.

The car is not overheating if the temp gauge goes up and down by turning the lights on and off.  The gauge is giving you bad information.   You can confirm this by starting the car from cold, sitting in the driveway, let the temp go to somewhere BEFORE normal operating temp, then turn on headlights and fan blower on high, watch the gauge, then turn them off.   If the gauge moves significantly from the electrical load, you probably have a short or a bad ground connection.  

You have a short circuit or bad wiring somewhere in the front half of the car.  I don't know what thermostat switch you have replaced ... but it's not the problem .. stop buying them.  
If you are the original owner, was there an accident that may have damaged some wiring?  If you bought the car second hand,  get a carfax and find out where the thing was hit ... concentrate your wiring trouble shooting in that area.

I think it is something OTHER than the temperature sending unit or the gauge
