Engine stop switch GL1000

Postby rustyparts » Fri Oct 02, 2015 12:49 pm



I'm back with a new dalamma. When using the start button with the ignition on I get nothing but if I turn the engine stop switch to off the bike cranks but not start. While the engine is cranking and the stop switch off I can turn the stop switch to on and the engine will continue to crank and start. The schematic shows to have a resistor in that circuit and I'm thinking that may be bad and when starting the bike like that it bypasses the resistor. Part of my problem is that I can't locate that resistor and the other is that may not be the problem. Is there anyone who can shed some light on my problem?

Look at the schematic..You will see that the resistor on your bike will be OK.You probably have issues with the bypass circuit.
To get a better spark during cranking,when you push the start button,power is applied to a diode which is hooked directly to the coils.
This gives them a bit of a boost to increase the spark.

I think your onto something here. My problem began as a dim headlight and voltage to both high and low beam at the same time. I replaced the highting unit and solved the problem of voltage to high and low beam but the light is still dim. Is the diode your speaking of one of the 4 on the left side of the side shelter? I've checked all 4 of them and changed them around and that made no difference. I am thinking that all the problems are somewhere in this circuit. Please reply.

Update:
I have found my problem, after double checking the diode from the starter selonoid and no problem there I ohmed the starter button and it checked good. I began to examine the the bullet connectors related to the starter button and the stop switch, there are 2 black wires going to the switches and one black wire coming from the switches. The color schematic shows the wire coming from the diode to the engine stop switch to be orange/black when in reality it is solid black with an orange coller at the connector. The orange/black wire from the stop switch had been crossed to the black wire from the ignition switch. I found this out by going back to my other "76 and comparing the two. After switching the two wires my stop switch and my starter button work fine and my headlight is as bright as a diesel train. Virgilmobile I appreciate your responding. Thanks Rusty

Glad you sorted it out.Good catch.
