    The two open threaded holes on the filter, have already bothered me when the HellFighter arrived...

    Hi everyone, Im new to the forum so go easy on me!

    I've recently gotten my hands on a Hellfighter and want to get it running well. I have easy access to the 2590 batteries, however the cable assembly that I have with the hellfighter does not have the battery end connection. As such I was hoping to modify this other cable I have to do the job, only problem is when I plug it all up it seems like The voltage drops from the battery. I know the battery is good, so I was wondering if I have it wired wrong?? Going with White is positive from the surefire cable and Black is neg.

    With the other cable set up I wasnt sure what the third (black) wire was for, any ideas?

    Living in Australia means the only way I can get the surefire cables really is to pay an absolute mint from surefire directly, I may end up buying one from the US and just sucking it up with like 40dollars postage.

    Thanks,

    John

    eBay is your friend on Surefire cables. They're under $25 USD plus shipping.

    If I get a chance later today, I'll pin out a cable and let you know what's what.
    Those that can, do. Those that can't, teach.

    The A and C pins I shorted with a white wire because that's what an external switch usually connects to, for remotely turning it on and off.
    B is positive and E is negative.
    D is unused.
    You'll need to test the cable with a multimeter to figure out what connects to where.

    Thanks for the photo, I had a bit play around with it at work yesterday with an electrical technician who deals with stuff like this all the time and we couldnt get the light to work at all. There is the chance that the light is faulty but I guess this is unlikely given the quality of most surefire stuff.

    Using the genuine cable which we had cut the end off and connected those wires to a 12v batt wouldnt work at all. what was really strange was the cable began to heat up quickly. Noting we have the polarity correct it was very strange. Have you guys seen anything like this when you are using an alternate power source?

    Thanks, John

    Hi again guys, ive done some more fault finding. This time with a cable a guy from work has used previously on a HF and it worked for him fine.

    Essentially a UH02 cable with the battery end removed and spliced in pos and neg to a cable which plugs directly into a 2590 battery.

    Whats interesting was checking the volts in the line prior to connecting to the HF from a fully charged 2590 was around 16v, then on connecting to the HF volts immediately droped to .546 v dc.

    Has anyone seen this before? Does the torch have an internal fuse which may have blown?

    In the interest of full disclosure the tech guys at work origianally tried a 2590 connector which rigged in series, so the HF has has almost 30v dc put to it the other day. Could this cause a fault to the internals?

    Any help would be aweaome, cheers.

    John

    No I haven't tested the runtime, but I think the light uses 3-4 amps, so a single pack should do 1.5-2hrs.
    I need the four packs because when I upgrade it to LED it will be using twice as much current.

    When does the low voltage cutoff kick in?
    It must be this PCB in the back right?

    I removed this when making my connector mod, so now I just watch the voltage on the battery pack.
    I'm not sure about the low voltage cutoff, but I'm pretty sure this is also e-switch circuitry because the handle power button isn't connected in line to the power.
    Hi Enderman mate how are you going?

    So I have posted to this thread recently as I was having a nightmare getting my two Hellfighter units running! This evening I had a little success. It appears that when myself and the Tech heads at work stupidly attached a 2590 battery up to the unit with a plug hardwired in series that we fried this part of the unit! Now whenever we plug the correct battery up to the unit the voltage drops to like .5 v from the original 12.

    To night I removed this part of the unit and just jumped the powersource to the rear of the HF itself and bingo! the light started up fine.

    So my next question is should I:

    A: bypass this regulator entirely and only run the unit of 2590 batteries.

    B: Attempt to repair the regulator?

    I need to go and get my hands on a suitable pin wrench tomorrow to get access to the board as seen in your pic to find out which part it actually burnt out! But if possible I would prefer to go with option B.

    You guys on here come across as knowing your stuff really well, so please any advice is appreciated!

    Cheers, John. (PS: Im posting from Aus so I have troubles getting my hands on any SF parts, ideally I will need to make this repair on two HF units as it appears we fried both

    That is awesome looking.Make me one of the custom battery cases I'd gladly buy one
    WTB any of the older sf lights, digital series , crosshairs.Also looking for SF displays , please leave PM thanks

    Are you referring to my battery case?
    If so, thanks

    I am just using my Hellfighter 4. I had bought one and the internal battery was dead, sent it to Surefire and after 4 weeks they sent it back fixed for free!!!

    Now that you've got a 4, you need to find the pistol grip switch and cable assembly. With the grip, you get a high and low setting as well as strobe. Without, it's high only.

    Just use any 12v battery, doesn't need to be the special military ones.
