johnsilver Posted October 8, 2006 Report Share Posted October 8, 2006 I'm measuring the output resistance from two Seymour Duncan pickups I just bought - a Custom bridge and Pearly Gates neck. When I measure the resistance on my multimeter, I get only about 1/2 the output posted on the SD site. When I measure a Duncan 59 that I have already, I get the correct reading. The two new ones have gold covers and the 59 is without a cover. Any ideas? Quote Link to comment Share on other sites More sharing options...
spazzyone Posted October 8, 2006 Report Share Posted October 8, 2006 It sounds like you are either mesuring one coil or its wired parallel the SHPG-1 Pearly Gates should be 7.3k so half would be 3.65 in single coil or aprox 5.11 in parallel do either these readings sound like what your getting post how you have them wired (color wise) and your readings as far as the custom wich model # as there are several from duncan Quote Link to comment Share on other sites More sharing options...
JoeAArthur Posted October 8, 2006 Report Share Posted October 8, 2006 Actually two 3.65 coils in parallel would be 1.825K, half of a single coil reading. Quote Link to comment Share on other sites More sharing options...
spazzyone Posted October 8, 2006 Report Share Posted October 8, 2006 thats what i thought but on the SD site it says parallel is - 30% of series thus 5.11 Quote Link to comment Share on other sites More sharing options...
johnsilver Posted October 8, 2006 Author Report Share Posted October 8, 2006 Guys, thanks. I figured it out that I was only measuring one coil on each, thus roughly half the reading (i.e. 3.58 for the PG and 7.13 for the Custom). When I twisted the wires as they would be installed and then tested, I got the correct reading. Quote Link to comment Share on other sites More sharing options...

Logical Frank Posted October 9, 2006 Report Share Posted October 9, 2006 Parallel would be 25% of series.... Half the rated DC resistance would mean you've only got one coil or there's something wrong w/ it. Quote Link to comment Share on other sites More sharing options...
spazzyone Posted October 9, 2006 Report Share Posted October 9, 2006 You are correct it does say 30% less power not resistance i stand corrected Quote Link to comment Share on other sites More sharing options...
