eazyste Posted March 14, 2013 Report Share Posted March 14, 2013 I've just had my 2011 pro frame powder coated and after putting it back together I don't have a spark, I've cleaned around the engine mounts to make sure the engine had a good earth. My question is ... Where the coil fastens to the frame do both mounts have to be clear to earth, or just the top or just the bottom? Any one else had any similar problems? Thanks in advance Steve Quote Link to comment Share on other sites More sharing options...
ducati996 Posted March 14, 2013 Report Share Posted March 14, 2013 Sounds like a bad earth,i would clean to bare metal both coil mounts 1 Quote Link to comment Share on other sites More sharing options...
0007 Posted March 14, 2013 Report Share Posted March 14, 2013 Why don't you try checking continuity to ground averywhere you are supposed to It all should have extremely low resistance to the engine cases You can test to see if the coil has contact to the frame and if the engine has good contact with the frame etc Your meter can answer a lot of questions And don't forget to test the kill switch 1 Quote Link to comment Share on other sites More sharing options...
eazyste Posted March 16, 2013 Author Report Share Posted March 16, 2013 Thanks guys, so just to clarify before I go scraping powder coating of mounts, both sides of the coil need to be clear to the frame? Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted March 17, 2013 Report Share Posted March 17, 2013 Depending on how the coil is wired, you probably only need one of the tabs scraped to bare metal. WIth an ohm meter you should be able to figure out which one. But, why worry about it, scrape them both to be sure you have a good electrical ground (earth in UK). 1 Quote Link to comment Share on other sites More sharing options...
sting32 Posted March 19, 2013 Report Share Posted March 19, 2013 I would think "yes' on that Easyste. Coil has to be grounded, might as well be REDUNDANT, as it is extremely important for it to be able "fire" the plug, you know... and will be sad/pain to trouble shoot when it isn't grounded perfectly good. IMHO. do just one if you want, I wouldn't, but that is just me... Quote Link to comment Share on other sites More sharing options...
