| Hmm , odd. To be clear: the sense wires are on separate cables connected to the battery? Can you make sure the cables are ok and not got any faults? |

i have two 'thick' wires going to the pos and neg of the battery - these connect to the 'power' on the regulator
i have two 'thinner' wires going the the pos and neg of the battery - connected to the 'sense' on the regulator
and i have put a light bulb via wires into the 'load' of the regulator,
i have checked the continiuity of the wires and they're all fine.. any ideas? |

right so it sounds like its correctly connected ..
Can you check that there is definitely 12v on the end of the sense wires at the connector blocks with it wired in?
Just making sure it is all ok.
One thought , the legs of the LED's could have touched together making it seem like its not working.
If you want to, open the case by taking off the white tape on the back and taking out the screws and checking everything inside, it should look like the picture below except with yours the heatsink goes outside of the case and theres two FET's.

agrifabs, sent you an email back but thought I'd post it here in case:
Ah, I think I see the problem,(references to position as in picture)
To be clear the sense wires are on the 'thin' wires going to the circuit board, the battery connection is in the middle and the load is on the left two connectors. Not sure how I mislabelled it but that must be it - sorry :)
The positive connection for each of these is on the left connector in each block of two.
Makes it obvious why it wasnt working I guess..
Lets see if this works ..
LOAD-----POWER---SENSE

ok, i hope this is it now!... i was going to 'scribe' those markings into the box with my dremel when i recieved it, thank god i didnt!! perhaps you could do that before you ship them out because its easy for those markings to get rubbed off!
ill let you know how i get on!

| I didnt want to make the markings permanent as some people might not want them which is why I did it that way -BTW I would only use a light bulb for testing, I think ghurd said that he used a lightbulb on one and it blew up in only a few hours. |

| argh - 'The positive connection for each of these is on the left connector' should mean 'right connector' , swap the leads round on each pair .. |
