Morning!

 

I am looking to put together a proper test rig for the HID kits I sell. Now, I know just about bugger all about wiring up electronics so thought I'd pass this by some of you who "are in the know" before I c*ck it up.

 

Please have a look at the attached wiring diagram I quickly threw together. Basically, I have a 12V battery, a rocker switch and a wiring loom connector. How do I connect everything up so that I can use the rocker switch to turn the HID bulb on and off at will? The rocker switch I bought from Maplins yesterday has two terminals on the back marked "1" and "2". I take it this relates to positive and negative connection. If I connect the lot up as per the attached diagram - will anything work? If not could you explain how I need to run the wires to make this work? Incidentally, I also saw another style of rocker switch whilst at Maplins - this had four terminals on the back with a pair of "1" & "2"'s marked. If I had bought that type of switch would I have connected the positive and negative wires coming from the battery to a pair of "1" and "2" and then connect the positive and negative wires coming from the wiring loom connector to the other "1" and "2" terminals?

 

Many thanks for your time and explanations! Please assume I'm "thick" where it concerns electronics so layman's terms are most welcome!

 

Cheerio!

Yeah, that should work - can't go far wrong with that.

And a switch with four connections would normally be a double pole - don't worry about it - not needed in this instance.

Many thanks for that Andy - nice to see that common sense hasn't let me donw today! ;)

 

Cheers,

maybe wire in an in-line fuse? if the unit is faulty and is drawing too much current you may not notice... i might be talking rubbish here but just an idea ;)

Good idea - what fuse to get though...

 

The battery is rated at 7.2Ah and the bulb draws around 3Ah current so presumably a 5Ah fuse will do the trick?

no idea lol... is there a standard fuse for the headlamps from the factory?

in the instructions with your kits it says to uprate your headlight fuse (to 15A iirc)

doh, didnt read that part... nevermind, iv removed mine now to sell the car :(

Amps equals watts divided by volts, so if it's a 60 watt bulb (HID isn't), divided by 12 volts equals 5 amps. So 5 amps would be sufficient for a single HID.

Amps=Volts Divided by Watts

Example

If the bulb was 100W,12v into 100=8.3 Amps

HTH! ;)

Bugger!-too slow! :D

Bugger!-too slow! :D

 

Cheers for all the help chaps! Much appreciated. I think I'm on the right track now.

Dont connect the positive AND the negative (1 and 2 on the switch) to the battery. Connect 1 to battery positive and 2 to the HID bulb/ballast positive. connect negative direct to other side (nagative) of HID bulb/ballast

As in that diagram really :nelson:

And yes, an in-line fuse is a good idea
