Coils wont fire,and hit start button and wont turn over,can jump starter relay and will turn over

Sounds like you have a weak battery, test the voltage. If battery is fine then your starter relay is the culprit. Clean all terminals in battery and relay, corrosion on the connectors will cause this too

You ave bad ground connector from the engine to the frame or from the frame to battery,all the best.

I think the purple wire (or maybe the yellow) from the neutral safety switch goes to the coil side of the starter relay, turning it on so power is sent from there to the starter solenoid. You could check for this signal to the relay with a test light. The key must be held in start while you probe the other two terminals for the relay. If the signal is there, either a bad relay or the coil side of relay is not grounded properly. It is possible that the coil side ground is the neutral safety switch-grounding the relay's coil side only in park or neutral-in which case the nagging light on shifter (between off and run, it only works?) may be telling you the safety switch is the problem.

You may need to look at a wiring diagram, Greg. But the starter relay is the last component in the start circuit before the starter solenoid. From battery to ignition switch to "crank" fuse to neutral safety switch to starter relay to starter solenoid to starter-and back to battery through ground. That is the start circuit. Just that the wiring tying them all together makes it complicated.

remove starter button cluster and check wires for corrosion etc as they can get weather in ! touch the two button wires together as if to start , if yes the prob is the button so if its a sealed part replace it ! P....

follow the wire from the starter button to the first connector unplug it and get a jumper wire connect in one side and touch it to the other side should only be two wires with key on if starter rolls then it is the starter button need cleaning or replacing

check fuel filter and shut off in float chamber , if you have spark and gas , still not firing check timing .

The starter could be drawing too many amps, if thats the case it will need to be replaced. Also the solenoid. When you say there is "no spark" you mean the spark plugs are not firing? When the bike cranks it will not start?

Hi and welcome to FixYa,

Initially, is there an alarm/immobilizer? If yes is it active/enabled?

Offhand, by "...wont start..." do you mean starter motor will not spin or engine turns but will not fire?

Starter motor will not turn:

• press start button, check for +12 on green/black wire from starter switch to starter relay;
• if there is, is there a clicking sound?
• if there is a clicking sound, short temporarily the 2 big terminals of the starter relay;
• if starter motor turns, starter relay faulty;
• if not, starter motor needs looking into particularly the carbon brushes and the commutator segments.

Starter motor turns but no spark:

• check/replace sparkplug;
• check pulsating voltage on green/white wire going to ignition coil coming from the ignition control unit;
• check pulsating low AC voltage on green wire going to ignition control unit coming from the pulse generator coil;
• check presence of IGN +12 leading to the ignition control unit.
  

Starter motor turns, there is spark but motor will not run:

• check automatic choke (blue & white/black wires);
• check fuel quality and quantity delivered to combustion chamber (check sparkplug if wet).

Good luck and thank you for asking FixYa.

bad starter relay, not sure where its located.

you don't hit the alternator, you hit the starter to help is shake free because it is already going bad. take battery and alternator to parts store and have both tested. check the wires at the starter and make sure they are on SECURELY. very important SOLID CONTACT is occurring. do your lights turn on? check starter relay if the eclipse is equipped with one.
