stavinor Posted November 7, 2017 Share Posted November 7, 2017 Been having a small issue with my bike. It starts fine however when I go on a small ride out and turn the bike off. When I turn it back on it sometimes wont start. I have to Pull the clutch in and open the throttle and it starts. However today it was raining I just on my way back from its MOT and it cut out about 40 MPH. At the side of the road it was trying to start back up but when I put it into first gear it instantly died. Eventually the battery went and I had to push it home. I got the battery on charge now. When I start it it Idles for a few minuets then cuts out and wont start again.Anyone have any ideas what it could be? Quote Link to comment Share on other sites More sharing options...
Guest Posted November 7, 2017 Share Posted November 7, 2017 Does it start ok on a charged battery - then die again after a bit? If so, it could be the regulator not charging the battery. To find out, check voltage across battery with engine running - should be about 14 V. Quote Link to comment Share on other sites More sharing options...
stavinor Posted November 7, 2017 Author Share Posted November 7, 2017 Thank you for your reply. I have it on charge at the moment after its reading 13.1 volts and 20 amps. After an hour of charging I started the bike fine it ran for about 30 seconds then cut out and then wouldn't start. I then left it and tried it again it was the same scenario. However the second time it started then again but cut out after 5 seconds. Someone suggested it could be the side stand sensor? Quote Link to comment Share on other sites More sharing options...
stavinor Posted November 7, 2017 Author Share Posted November 7, 2017 Sorry that was when it was charging. When it runs it 14.1 volts and 83 amps. Kind RegardsScott Quote Link to comment Share on other sites More sharing options...
Guest Posted November 7, 2017 Share Posted November 7, 2017 How are you measuring the current? 83 A sounds a bit steep to me. Are you sure the battery is OK? Quote Link to comment Share on other sites More sharing options...
stavinor Posted November 7, 2017 Author Share Posted November 7, 2017 Its just the readout from the battery charger. Quote Link to comment Share on other sites More sharing options...
Guest Posted November 7, 2017 Share Posted November 7, 2017 (edited) When charging a battery, max current should be capacity of battery in Ah/5 so on the charger, you should be reading about 3.5 A max. I suspect you've got an internal short - can you try blagging another battery from somewhere and seeing if that makes a difference?
