Current flow question

[MMACH 5]

So the drivers I ordered, back in February from DX, finally showed up.

I know that it will run battery to driver to lamp and then back to battery.

However, does it matter which side of the battery the driver is wired into?
i.e.—Does the driver need to be attached to the wire coming off the (+) or (-) post? Or does it make any difference?

Thanks for helping a noob out.

 

[HEY HEY ITS HENDO]

can you post a link for the driver you got from DX,
it will make it easier to explain where you are going wrong
and may make it easier for you to understand how to wire it up ....

Two wires run from battery to driver and back to battery. Typically you need a switch on one of the wires.
Two more wires run from driver to LED, Typically these are hard wired(no switch, no connectors).

On a typical flashlight driver there is a center pad and an outer ring, both on the opposite side to the + and - wires. The battery is connected to these pads, center pad is + and the outer ring -.

I got a P7 driver in from either DX or Kai, and it just has a red and black wire! No idea what to do with this.

This is the driver I got

And I'll be running off a 4.0A 6V NiMH battery with a Cree XR-E. The switch is built into the headlight housing I'll be using. So, yea, I left the switch off of my original post (oops).
The circuit then runs battery>switch>driver>lamp>battery
I just need to know if the lamp needs the driver between itself and the hot post or the negative post. I would hate to fry this thing the first time I turn it on.

Thanks again.

The two wires each go to the LED. The inside pad on the bottom of the driver connects to positive on the battery and the outer ring connects to negative on the battery. It should be switched on the battery side so as not to fry the board.

The circuit runs battery>switch>board>LED+>LED->board>battery.

ahhhh

Thank you, LukeA. I'm pretty sure you just saved me a big headache. I didn't realize I needed to connect up to the back of the board.

I'll let you know how it goes today.

I got it all finished and re-assembled at about 1:00am. Consequently, I overslept and didn't get to ride my bike to work, this morning.

The one surprise I had was with the silver, heatsink compound. That stuff gets on EVERYTHING. I may have overused it on my first application, but I had to dis-assemble the light to re-route the wires. This gave me a chance to clean it up and go with a lesser amount.

I'll try to get some shots of how it came out.

Thanks again.
