No start

[jeffschnase]

Good morning everyone. My 95 1st gen doesnt do the all familiar rattle when I turn on the key. I checked all the connections, replaced the battery, (it was in bad shape anyway), and still nothing. I hit the starter button and nothing. When I turn on the key the green nuetral light comes on along with the head light and tailight. When I hit the button the headlight goes off the way its supposed to. If I jump across the starter relay the engine turns over but it wont start. HELP!!!

Where's MaxMidnight's procedure diagram?

What about the sidestand switch?

It worked fine before all this went wrong. Im not sure what the procedure is to check it if the bikes not running.

Not sure which one you are referring to, the only one I can think of is the one for checking charging.

Jeff, when you say 'nothing' I assume you mean the starter doesn't turn?

It's time to get the multi-meter out. Can we assume you have c. 12.7 volts at the battery?
Given that you have head, tail and neutral lights the main feed (brown wire) and associated earths should be OK.
Have you checked that you have 12v both sides of the ignition fuse?
The neutral light gets power from the starter cut-out relay and I'm assuming the feed comes via the stop switch and cut-off relay which would suggest that part of the circuit is working. Check you have 12v on the red/black wire at the cut-out relay.
When you press the starter do you get 12v at the red/ white wire at the starter solenoid?

If that checks out then my best guess is that there is a problem with either the side stand or clutch switches or associate wiring.
The side stand switch should have continuity when up and open circuit when down.
Also check the clutch switch, you should have continuity with the lever pulled in and open circuit with the lever out.
If OK then check continuity of the blue/ yellow wires to the diode block and ICU.

When you press 'Start' do the oil and fuel level lights come on? They get their feed via the stop switch.
If not have you checked the 'Run' switch for continuity and that you have 12v at the red/ white wire going to it?
If yes, have you checked continuity from the stop switch red/ green wire to the ignition control unit (ICU) and starter.

A fair bit to be going on with, I hope it helps.

Probably he must try to jump start first.

I had a conversation with Jeff, and I'll wait until he posts his follow-up. He solved the issue.
