Hello all, new to this forum but I am at a stand still after not being able to figure out what is wrong.
I have a 89 454 ltd. I was riding around, running errands etc. and i finally get home. I turn the bike off and walk away for a few hours to do some work, i come back to go run another errand but the bike would not start. I was confused because it was running and starting fine that day. I assume a fuse blew so I check all my fuses. They were ALL fine. So i begin to go through the whole electrical system. I have a service manual for the bike and i have gone through the whole wiring system to control the ignition, starting, everything. I still couldnt fix it. All my grounds are tight.
First i went into the starter switch and all the wires were getting the voltage it needed, I crossed the solenoid with a screwdriver to see if it would turn, it did and it cranked right up. The starter relay which is next to the solenoid was working properly.
Now i have three theorys as to why it might not work from my knowledge.
1:The solenoid is bad because even when i cross a wire from the hot wire terminal to where the relay hooks up to the solenoid it still wouldnt crank, i have a voltmeter hooked to the wire im using to cross the solenoid and it has 12 volts going through it, but the solenoid wont work, so i assume the solenoid is busted and the crosswire im using to it wont tell the solenoid to open to send the power to the starter.
2:The IC Igniter is busted somehow(from what little i know about electrical) the relay connector comes from the Igniter (the same one that hooks up to the solenoid) and i am only getting maybe 0.15 volts coming from the igniter to the connector, and even when i press the start button i still get the same amount of voltage. So something maybe in the Igniter is not giving the voltage it needs, im not sure.
3:The Diode under the seat,the red one with a black box on it, i noticed is connected to the Starter Relay that is next to the solenoid. I noticed the three brown Brown/White wires that come off of the Red Diode CONNECTED give off 0.60 volts. But when i disconnect the diode and test the connector to the diode it gives off 7.3 volts. I dont know if this is normal but the 3 wires according to the wiring diagram go into the IC Igniter. So like #2 I dont know if the IC Igniter is the problem or the diode is responsible for not giving enough power to the IC Igniter and therefore the igniter doesnt give enough to the solenoid. Im not sure, which is why im stumped.
ALL HELP IS MUCH APPRECIATED!!
Any suggestions or any theorys and anyway i can help clarify my explanation feel free to ask would be the best of help. I'd rather have my bike fixed so i dont have to jump it with a screwdriver everytime i turn it off haha.
Thank you.
