The two wires that are running from my ballast that connect to the oem headlight connectors are white and black, any idea which is negative and which is positive. I have read other tutorials and everyone else's seem to be red and blue. Is there a way for me to test it and see? Its a Mcculloch Kit..

 

White is concidered in the electical/eletronics world as Neutral.
I am very surprised your kit doesn't give you guidence on this.

I was going to say just the opposite, I have installed two different brands of HID's and black was negative on both sets.

 

I was thinking black was negative. looks like we got 1 for 1 anyone else wanna add .02

 

In most of the electronics that I have dealt with black or green is ground(-) and white or red is hot(+). It looks like MB uses brown for ground.

 

I have a HID question since this thread is up, What type of bulb do crossfires have? Also anyone know the tail light bulb type?

 

H7 for headlight
7528 for tailight

12 Volt DC black is neutral.....now AC that would be white is neutral.

Big difference from car to house.

Wiring a boat gets real interesting...you have the 12 volt system and your household ac system all in the same place...

 

You guys amaze me with your INSANELY informative replies! Thanks a **** load!

 

this is getting confusing....

 

Where did you buy your HID kit where it doesn't have a install guide?!?!

 

Long story short.... Bought the HID Kit about 1 1/2 years ago, installed it myself (which was a biotch btw) and then a little bit later I was having issues with he headlights fogging up, based on past experience with my local dealers I knew they would try and blame everything and anything for causing this issue. I didn't wanna give them more reason to weasel there way out of fixing my headlights so I removed the HIDs. Now about a year later I want to reinstall them, however after moving twice within the year, they have been misplaced. I was hoping that someone here on the forums might have the same McCulloch HID and maybe able to tell me which one was which. Sorry for the inconvenience guys.

 

Chase,
Did you try going online to McCulloch and getting the instructions? Many manufacturers have pdf files for their instructions available.

 

The simple check is to use a voltmeter/multimeter or a 12 volt bulb attached to two wires. Attach one wire from the bulb or the negative probe of the voltmeter to a good earth on the car frame and then touch the wire that you are checking to the other wire or positive probe, if the bulb lights or the meter shows 12 volts you have found the positive. Touching two negative wires or two positive wires will not light the bulb or show any movement on the meter. Check that the bulb is not broken by touching the two wires to the positive and negative battery posts.

Of course the battery has to be connected, the switch turned to the correct position that operates the headlight and the voltmeter/multimeter set to the correct voltage range. Take care that all other wires are not touching the car body in any way. Cheap voltage testers with a suitable range, with a light inside are readily available and easy to use.

Multimeter's capable of measuring low Ohm values with digital read outs are also invaluable to check any suspect car sensors. You can save a lot of money when you can prove that your crankshaft position sensor is broken and not rely on a dealer to do it for you.
