1989 Honda Elite LX Electrical Problems

[mc1092]

Hi. I am new to the scooter world and I have fully restored a 1989 Honda Elite LX SA50. When I rode it around yesterday I pulled into the driveway and turned the key to the off position and turned the killswitch to off; however, my scooter was still running. I had to pull the cable running to the sparkplug inorder to shut it off. Is there something wrong with my killswitch, ignition, or relay? And if so, how can I fix this problem?

Welcome.
Perhaps a wire is loose? A ground wire? Try giving it a thorough inspection.
Start with the least expensive items. It could very well be an ignition or kill-switch, but I would rule out other possibilities first.
Good Luck and Happy Trails!

Bonesv your electrical troubleshooting is not very helpful.

we can probably assume that both switches did not go bad at the same time. so that only leaves one possibility......the kill wire has opened up somewhere.

It is a black wire with a white stripe that starts at the cdi box and runs to the key switch then to the kill switch on the handle bars.

Start your search there.

Either that or the two switches lost the ground in the head set.

Do the key switch and the kill switch share the same ground wire on the LX?

This is getting old BUT

Find your service manual here and answer your own question.

I checked continuity between both the killswitch and ignition switch and both worked fine. There is also continuity from the killwire and groundwire from the front to the cdi unit. What else could be keeping the killswitch and ignition switch from killing the motor? Also the service manual does not address this problem in troubleshooting or wiring diagrams.

NO GROUND TO THE SWITCHES MEANS NO SHUT OFF OF THE IGNITION! All the continuity in the world between the switches and the CDI means nothing if you do not have a good ground to the switch.

Ok but what do these switches ground to? What color is the ground wire?

Look in the manual, there is a wiring diagram. Why are you messing with the wiring without looking what wire is what and what color? With Honda ground is always green.

[mc1092]

I have studied the wiring diagram. It does not designate where the green groundwire grounds to. Does the ground wire ground to the frame or someplace else?

[Bear45-70]

If you knew how to read the diagram you would know that all grounds end up at the frame ground which is also the negative battery terminal. That little upside down Christmas tree is frame ground.

Ok that's what I was thinking. Thank you for your help

Ok so can anyone tell me how the whole engine kill works from the killswitch or ignition key turned to the engine being turned off, where the electricity flows?

The engine kill wire is black with a white stripe.

The black/white wire comes from the cdi and goes to the key switch, then goes to the kill switch on the handle bars.

If this black/white wire gets shorted to ground (always a green wire), the cdi stops sending pulses to the coil.

Both switches in the "run" position are open (not shorted to ground).
