Want to Bench test my xenons before I install on the car to save time taking headlamps off and dissembling and re assembling them.

I have a trickle charger than manages 5amps and barely lights the bulb. I have read it needs to be 8amps

Went to B&Q today and came home with a 2/8/12 "switchable" power pack, however it's an "intelligent" one do if it doesn't sense a battery connected it quite simply does nothing.

Most I have found are upwards of £90.

Anyone on CS Got a suggestion or bit of equipment they use?

Needs to ignit rebased H1 HIDs and 35w ballasts for a max of about 30mins. At this rate I could just buy a battery but this is something I can use afterwards.

Halp!

What about few bits of wire and a battery booster pack? Done it a few times with cd/dvd players etc. Works a treat

these things - http://www.ebay.co.uk/itm/12V-900A-HEAVY-DUTY-CAR-JUMP-STARTER-START-BOOSTER-CABLE-LEAD-BATTERY-BOOSTER-/290670077106?pt=UK_Recovery_Tools&hash=item43ad4964b2

has a 12Ah battery, so could dump 12A for up to an hour. Easily do 8A for some lights for a while.

This is what I do too, handy to have for when you/a friend has a flat battery too.

That's approximately 892 amps more than I need. Think the igniters would explode

The lights will only take the current they want/need.

This is the important point. Voltage is important, current less so, as the lights will draw what they need only.

you have a laptop power supply that supplys 8A??? Most are only like 3-4A

Btw, you van get those jump start units in maplins for about £25. And yep, as that other guy said, amperage is only supplied as the device draws it, so it'll only supply 8A if you're lights draw 8A. It can supply *UPTO* 900A (all be it for a very short time period, and would likely break)

They are rare but they exist. However Xbox power supply is plenty powerful.

Going to see if I have my old one kicking around the garage.

Do you have any PC power supplies knocking about?


Basically solder all the 12v cables together and the ground/- cables and there you go, 12V source. These are very stable, I have had a few chargers running off one drawings around 20amps or so with no problems at all.

Yeah im aware of the PC thing, but I dont have a spare and dont fancy taking a PC apart then soldering minute contacts. I dont have the skill for that.

I can manage chopping a plug off, twisting some wires together soldering and adding some connectors on the end and voila, I have a power pack!

If you can get hold of a PC PSU, then you basically just do what you have described in your 2nd sentence
