skabo1 Posted February 15, 2014 Report Share Posted February 15, 2014 My club bought a GDK trading, double arm, auto trap with the radio release option. Whilst putting the thing together the lead that connects to the radio receiver module and battery became tangled with an arm, the male plug that connects to the radio release module flew off and was lost . I have bought a new plug from Maplins and I am about to fit it to the lead but I don't know if the centre is positive or negative, if the circuit is not protected by a diode then connecting it incorrectly will cause serious damage, 99 times out of 100 times it is positive but I cannot be sure. I have contacted GDK trading but they have ignored my request for information, (says a lot ) can anyone help me please? if any of you kind people have one please do a continuity test on the lead. Thank you. Your kindness will be much appreciated in clay shooting circles Quote Link to comment Share on other sites More sharing options...

Kermit the frog Posted February 24, 2014 Report Share Posted February 24, 2014 Have had a few people ring me to fix GDK traps that don't work, and they can't get any help from the suppliers Kermit Quote Link to comment Share on other sites More sharing options...

FatherandSon Posted February 25, 2014 Report Share Posted February 25, 2014 Not sure but Liar Liar is on Sky Comedy at 11.15!!! Sorry! An educated guess would be the positive would be the inner (more protected) one. Quote Link to comment Share on other sites More sharing options...
tedster Posted February 26, 2014 Report Share Posted February 26, 2014 Can't you attach a multi-meter to the connector on volts setting, it'll tell you the polarity. Quote Link to comment Share on other sites More sharing options...
skabo1 Posted February 27, 2014 Author Report Share Posted February 27, 2014 Can't you attach a multi-meter to the connector on volts setting, it'll tell you the polarity. It's not the lead I need to find the polarity of, I can make that either or, it's the radio release module socket I need to know the polarity requirement of, it has no potential until it is connected to the battery using the lead I now need to make, but thanks tedster, I appreciate any help..

tedster Posted February 28, 2014 Report Share Posted February 28, 2014 Ah, I get you now, can you remove the cover off the module, maybe check the circuit board for any polarity marks? Quote Link to comment Share on other sites More sharing options...
skabo1 Posted February 28, 2014 Author Report Share Posted February 28, 2014 Ah, I get you now, can you remove the cover off the module, maybe check the circuit board for any polarity marks? That will have to be my next move, a lot of people have confirmed to expect a + centre so I'm going for it. I'm sort of thinking that the manufacturers will be aware that the clips can so easily be connected to the wrong battery terminals and will have probably built diodes into the board to protect the components. I'm thinking if it was wrong the module may just not work, thanks for the support lads, much appreciated. JC Quote Link to comment Share on other sites More sharing options...
Kermit the frog Posted March 6, 2014 Report Share Posted March 6, 2014 Have you found out yet? kermit Quote Link to comment Share on other sites More sharing options...
skabo1 Posted March 9, 2014 Author Report Share Posted March 9, 2014 Have you found out yet? kermit Yes! I soldered it up with the centre positive and it worked as best a GDK trap can which is not at all good but at least it did work. The correct connection is positive centre, thanks to everybody who helped. Quote Link to comment Share on other sites More sharing options...
tedster Posted March 9, 2014 Report Share Posted March 9, 2014 Result Every so often, get some silicone spray and put a good dose on the (clean) platform and the rubber on the throwing arm. Makes the clays go much further and keeps it much cleaner. Quote Link to comment Share on other sites More sharing options...

Makes the clays go much further and keeps it much cleaner. Good tip, I'll try that next shoot, thanks! I've always believed in keeping the platten clean, I don't like to see that tarry deposit. There's a make of clay making an appearence which seem more bitumen'y than others, they even soften and twist when they get hot. Quote Link to comment Share on other sites More sharing options...
