Engine Swap Problems!!!!!!!!!!!!!

[90gs500]

Ok, so I've got the new engine in the bike and bolted in, I started hooking things up, but now I have problems...

When I turn the key, the only light that comes on is the neutral light.  No oil light, no headlight, no taillight, no brakelight, no blinkers, etc.  The only harness I haven't hooked up is the harness that goes to the ignition advancer area...

The fuse is good and I'm out of ideas...

So I'm calling on this forum, ONCE AGAIN for some guidance and help.

If anyone has any Idea's I'm open to try anything, I don't want to bolt the carb on or anything until I know whats goin on...

Thanks in advance for the help...

if i remember right the oil pressure sensor is behind the iginition plate, so that wire whouldn't be hooked up yet. so no oil light.  and it sounds like you may have missed a power lead some whare from the iginition to the lights. check the connections in the headlight bucket.

the next thing is the grounds, you may have a bad ground from the wire to the motor/frame so your not completing the circut on that end.  but you say you are getting a netural light. so then hook up the wires on the other side (iginition) if the oil light works then you know that you have a good ground  to the motor, and that the netural light isn't just a fluke. then the frame ground.

so when I took the advancer and stuff out, those three wires, the one below the advancer is the oil pressure switch?

ok, I'm still stumped on why the lights don't work and I tried to make it turn over with the starter and NOTHIN...

not having lights, tells me that when you turn the iginition on your not gettign power from the batt, to the headlight. so i don't think you hooked up the wires right in the iginition switch, or missed a connection in the bucket.   maybe ( I have been known to give crappy advice)  so anyway the diagram that Kerry mentions in the thread below will show you whare you need to go to figure it out.  do you have a test light so you can see if you have power? they are like 5 bucks at a auto parts store.  or if yoru really cheep take a 6 inch piece of wire and hold it against a 12 v  bulb on one of the contacts and then ground the bulb to the bike with the other contact and use the wire to find the power.

You need to look at this one problem at a time - although they may have a common cause.

Did you remember to connect the ground (negative, "-", black) cable from the lower part of the engine that runs to the battery negative side?

Does your starter relay even "click" when you push the start button?

Do you have John Bates' starter circuit schematic?

More basic question, have you ever learned to read a schematic? No shame if not. You just haven't been taught. I wasn't born with that knowledge either, just spent all my adult life and the end of my youth doing it.  

What exactly did you disconnect to swap out the engine? It should have been just the spark wires, the signal generator/oil pressure wire, the negative battery cable, the neutral indicator switch, and the starter motor cable.

What year chassis and motor are we talking about?

There. That's enough questions to get us rolling.
