Have an 03 1800S went to start this morning and it lagged just a little but started. Rode about 60 miles and ate lunch went to start it and wouldn't start. Figured was battery since 3 years old. Installed new battery from Honda dealership and still wont start. Was able to push start it and made it 45 miles back home. Once home still won't start when you push the button. The key is on bike in neutral and headlight is on. When you push the button the start it the headlight goes out but the bike won't crank. Doesn't turn over or nothing. No clicking sounds either. Any ideas?
And FYI...... you can't push start a EFI bike if the battery is dead for future reference. The fuel pump needs power to prime the fuel system, if the battery truly was your problem, push start would be out of the question. This is why you can rule out a bad battery in your particular case
A lot of starter solenoid problems lately. Are the Honda original parts serviceable? Or do you have to replace the whole sealed unit?
(I recall my old original starter solenoid on my big F350 diesel was serviceable - I could open it up, clean the contactors, reassemble and be good for another 100k miles)
