mmcm Posted May 29, 2014 Author Share Posted May 29, 2014 Hi airhead ok I will try one but it wont change anything. If I take the power input off the coil and put it to earth I should see a spark but I dont? I have gone through all the switches twice an they all seem fine. source coils dont give me the readings specified but they are generating a voltage when I attempt to start it. all wires appear to test ok up to the cdi box etc relays removed an tested an all appear to be functioning.

tomyqss Posted May 29, 2014 Share Posted May 29, 2014 have you ruled out the ht lead an cap? Link to comment Share on other sites More sharing options...
mmcm Posted May 29, 2014 Author Share Posted May 29, 2014 hi I have tested the ignition coil checking the primary an secondary an both give the correct values one if these means connecting to the end of the lead so I presume its good? Link to comment Share on other sites More sharing options...
mmcm Posted May 29, 2014 Author Share Posted May 29, 2014 plug cap fits tightly Link to comment Share on other sites More sharing options...

blackhat250 Posted May 29, 2014 Share Posted May 29, 2014 The kill switch must be grounded then ,, or wire from ignition , earthing where it passes thru headlamp, take coil off too, and clean frame where it mounts, Link to comment Share on other sites More sharing options...
mmcm Posted May 29, 2014 Author Share Posted May 29, 2014 I checked the kill switch for continuity and its appears to function correctly how would I check to see if its grounded? im now having problems with the ignition conection so have unplugged an bypassed as per the Haynes but im not sure its correct as there seems a few variations! I hopefully have someone whos into electrics that can maybe have a luck so fingers crossed! Link to comment Share on other sites More sharing options...
Moderator Airhead Posted June 14, 2014 Moderator Share Posted June 14, 2014 best check the resistance values of the coils in the stator, you'll find specs in the haynes manual, if they test as good it's probably a duff ecu? Link to comment Share on other sites More sharing options...
mmcm Posted June 16, 2014 Author Share Posted June 16, 2014 ok guys the solution! tested the coils in the stator an the ignition coil had burnt out! sent it away to be repaired which was alot cheaper than buying a new one:) returned good as new an sparked once fitted:) rebuilt having secured all wires an put tank on a tried to start her an nothin:( check for spark nothin:( after sometime I located the cause as being a nick in one of the ignition wires inside the barrel which was intermittently shorting out the system. Now back up an running like a dream! cheers for the help guys 1 Link to comment Share on other sites More sharing options...
Moderator Airhead Posted June 16, 2014 Moderator Share Posted June 16, 2014 good news but why not share the info of who wound the coil, and the cost? maybe post a link Link to comment Share on other sites More sharing options...
mmcm Posted June 17, 2014 Author Share Posted June 17, 2014 I had the coil re wound at west country windings and it cost £90 Link to comment Share on other sites More sharing options...
