thall1 Posted December 8, 2017 Report Share Posted December 8, 2017 this is the 'ignition generator check' as per an Evo 2013 4t manual (pg66) found on beta usa website under 'support'.....the check may be suitable for yours...... Disconnect black 12 way between the generator and CDI Disconnect the white 2 way connector between the generator and the wiring Black-White (pick-up) 320 ohm +/- 15% Red-Blue (condenser charging) 15 ohm +/- 15% ......not sure the 2008 has a condenser/capacitor on it? yellow-yellow (Service power supply) 0.6 ohm +/- 30% after having stripped a Montesa 4rt and a beta 4t loom i'd say the wiring seems to be generally pretty poor on the beta so it could just be a bad connection. There are some wiring diagrams on the Beta usa sight that are readable but they are from later bikes -2014 onwards I think, but it may give you a clue... good luck!

vectradam Posted December 10, 2017 Author Report Share Posted December 10, 2017 thanks very much for your help tried new plug and removed kill switch but no change. when you say 12 way connector thall1 i have a plug and socket with 6 wires in and 6 out . black - white i have open circuit yellow - yellow - 0.6 ohms red - blue - 15 ohms so its looking like the pick up is finished. anyone have any ideas of the best and cheapest solution ? many thanks for your help Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted December 10, 2017 Report Share Posted December 10, 2017 There are two places in the UK that can replace such components. Easily found by a search as I don't think I am permitted to name them on the forum. Quote Link to comment Share on other sites More sharing options...
