pignapper Posted March 28, 2017 Share Posted March 28, 2017 Hi guys. Not been on in a while. Hope all are well. Im after some help with a strange problem. 97 sr125. When i press the starter button i get strong voltage and good spark then it drops off and no spark. As i take finger off the button voltage grows again and spark returns. Obviously this all happens quickly but can been seen by eye and on meter. Im not the best with electrics so any help appriciated. Cheers Link to comment Share on other sites More sharing options...
finnerz89 Posted March 28, 2017 Share Posted March 28, 2017 Have you checked the starter relay and motor connectionsto see if they'reloose or corroded? Sent from my E6553 using Tapatalk Link to comment Share on other sites More sharing options...
Keith Inglis Posted March 29, 2017 Share Posted March 29, 2017 That would be a good start to check all connections first. Link to comment Share on other sites More sharing options...

finnerz89 Posted March 29, 2017 Share Posted March 29, 2017 Battery does sound suspect, either has a cell down or a bad connection somewhere is dragging the voltage down Sent from my E6553 using Tapatalk Link to comment Share on other sites More sharing options...
Joeltozer Posted March 6, 2021 Share Posted March 6, 2021 Any solution to this? I’ve got a TW125 with the same issue. changed the battery, spark plug and starter motor. Got a voltmeter to check where the electrical problem lies but hoped for answers here Link to comment Share on other sites More sharing options...
