QuestionI own a 1981 Suzuki GS850. Sometimes when you push the start button nothing would happen, other times it would fire up great. Last two weeks it quit startin all together.
I've been playing with electronics...
Here is what I got so far.
-The starter relay does not get 12V on its 3rd small wire terminal when the start button is pushed. When I jump the bike by conecting the 3rd terminal to the battery bike fires up.
- Folowing the line from the starter relay into "starter disconect switch" or the cluth leaver, I get nice continuity to the lever, and it closes the circuit nice.
-From there it goes to the Start button and engine kill. I've opened these up and they seem to work fine. But still no 12 volt all the way up here when I press the button.
-From the on switch there are 3 wires. One that goes through clutch lever switch to the starter relay, and two more. One goes to the ignitor and the other one goes to the fuse.
-I have checked every wire and rewired some connections, and the continuity seems to be good everywhere.
Here are my questions.
1. How does the 12V get to the starter button? Should the wire comming from the ignitor provide those 12 V?
2. What does the ignitor do? (This comes from the British manuel so I am not sure if American word is the same)
3. like I said earlier, when I jump the starter relay switch to the battery the bike starts cranking. The tank was off so I am not sure if it would run as well. I am thinking about making a wire that goes from the starter relay (the 3rd small conection), through the switch and straight to the battery. Bypass everything. Would the bike run properly? The only way to shut it off then would be by the key not the kill switch. Actually would even the key shut it off?
Thank you very much, for taking time to read my qustion.
AnswerHi Neb,
Try cleaning the starter button contacts.
Also, consider disconnecting the starter solenoid and applying 12VDC to the primary windings (small leads) for a second. The solenoid should click. If not, its not working properly. Check primary winding for continuity.
Here are my questions:
1. How does the 12V get to the starter button? Should the wire comming from the ignitor provide those 12 V?
Answer: Via the ignition switch.
2. What does the ignitor do?
Answer: Igniter or CDI/TCI is microprocessor that replaces breaker points and condenssors to deliver spark.
3. .....would the bike run properly?
Answer: Would not run properly. Avoid fabricating this new wiring. It may damage the electronics.
