palanchou Posted January 21, 2012 Posted January 21, 2012 hi. having problems with a intermittent weak spark.set plug lead 6 mm. from cyl. head, great spark, suspect ngk resistor plug cap. put plug only finger tight in head, kicked her over, no spark. can anyone help me, thanks bj.
blackhat250 Posted January 21, 2012 Posted January 21, 2012 Elimination process" change cheapest component first,, , do you have a meter " [ohms] and a manual ?
Moderator Airhead Posted January 21, 2012 Moderator Posted January 21, 2012 replace the plug and plug cap and try again, not really expensive to do
palanchou Posted January 22, 2012 Author Posted January 22, 2012 good morning,thanks blackchat &airhead for replying.got my haynes & multimeter.new points, new ig.coil. new wire from mag.resistance of mag coil ok. removed plug & ngk resistor plug cap . set ig. plug cable 6mm from cylinder, 4 out of 6 sparks only. thanks again. bj.
Moderator Airhead Posted January 22, 2012 Moderator Posted January 22, 2012 4 out of 6 eh, try disconnecting the capacitor during the checks? 10/10 ? new capacitor required !
palanchou Posted January 23, 2012 Author Posted January 23, 2012 thanks airhead, new capacitor& plug fitted, no joy took cap. out of the circuit, same result, thanks for all your help, b j.
Moderator Airhead Posted January 23, 2012 Moderator Posted January 23, 2012 do you have a haynes manual?
Moderator Airhead Posted January 29, 2012 Moderator Posted January 29, 2012 "thanks airhead, yes i have an haynes. today put ht lead 6mm from head bolt, great spark. screwed in plug, not connected to ht. lead, not a spark in site????????? any clues greatly appreciated bj." say that again?...but differently did you mean screwed in plug cap, fitted plug and rested on cylinder = no spark?
palanchou Posted January 31, 2012 Author Posted January 31, 2012 thanks airhead, no plug not connected to ignition coil lead, plug screwed into cyl. head, no spark what so ever thanks bj.
