Took some pics tonight, hopefully this harness is generic or similar to what you folks have seen. It is off the 110cc yamoto I pikced up this weekend that won't start , has no spark.

Pics here: http://tbsventures.net/bike/

In pic 0002 the wires I circled were not connected to anything , and there is nothing on the bike I can find to connect them to. The single wire has no voltage, 3 out of 4 wires in the plastic molex connector have +12v , the fourth is a ground.

Pic 003 shows something that is up front on the bike and I'm curious what its for.

Anyone got any input on this? Thanks !

 

pic 3 is your cid (controls spark and what not)
it's a little hard to tell what the other ones go to, can you edit a pic with lables for what you know the others were hooked to, it will make figuaring them out easier.
I have a diagram in my profile from a 110 lance.

At this point I know where everything goes except the 2 things in pic 002 that don't have anything on the bike to plug into. The single blue wire and the 4 wires in the white plastic connector. I'm very curious what would need 3 hots and a ground in one connector -- but I bet its probably important! : )

 

I gutted the harness and laid it all out, here's what I found.


Loose Wires with nothing plugged in and nothing obvious to plug them into

4 wire connector

red goes to ign switch
green is ground
yellow with red goes to starter switch and one side of starter relay
black goes to multiple locations , to cdi and to bundle with numerous black wires at front of bike



single blue wire

goes to stator harness and to kill switch

 

shot in the dark --> Some bikes have a remote kill. The 4 wire plug might have been set up to connect to the box for a remote kill?

 

hooked the harness back up today and connected a jumper from the pos battery side to the coil (like I swear I saw a thread about!) ,,, heard a sizzling sound from the coil - kinda like fajitas - and then a couple seconds of smoke from the coil , and now nothing. So I am back to where I started except now I probably have a shot coil. Ouch!

 

I think you were supposed to go from pos+ to starter to check starter and pull the spark plug (with wire attached) and ground to engine(touch engine w/ plug thread) push starter button and watch for spark at plug to test coil...

 

This page is a good one for how to test various components, Im still looking for the one that helped me fry the coil to see what I did wrong. : )

good site

And I just found the referring page that helped me toast my coil.

This is what I did.

Take a jumper wire from the + battery to the + coil terminal. Now have a friend crank the engine over while you hold the high voltage coil wire (point C) about 3/16 in. from ground. If you get a spark with the jumper wire on, then plug the high voltage coil wire back into the distributor and the motor probably will start. If it does, the problem is probably, first: (a) burned-out ballast resistor; (b) bad or broken connection (usually as the wire passes through the firewall); (c) bad contact at the key; or (d) broken or cut wire (in the middle of the wire, as opposed to (b), which is a bad connection at the end).

 

As long as you attach + to + you should be OK, unless there was a problem with it already. Could have been a dead short in the windings.
