1980 GS 450-wont start

[KitKat]

theres a way to test the r/r very quickly but i don't necessarily recommend it.

u can run the bike w/out the r/r, BUT don't do this for long at all (if i did it, which i probably wouldn't, i would not keep it runnign for more than 10 seconds like that)

Again, not recommending it, but it can be done as a quick test.

You're better off trying to decipher the stator papers

Will a r/r , and a ignitor from a 81;gs450t work on my 80'gs 450? Thanks,

Yes, both will work.

Good news!

Unfortunatly, after his ordeal both front and read right turning signals dont work, headlights out, and the break light is also not working

[chef1366]

The break light is broken?

[trintek]

so left turn signals are working and tail/running light is working? is the headlight not working on high and low beam or just one?

[djg42]

oops, that post wasnt clear.
The headlight is out(neither high or low beam work).
Both left side turning signals are out(front+rear)AND the brake light is out(is the brake light same as the tail/running light?). I checked the brake light, the bulb is burnt.

Both RIGHT side turning signals work.

Both RIGHT side turning signals work.

semi the same, bulb should have two filaments on the rear. regular light + bright for brakes.

so far it just sounds like a ground came unplugged, recheck the wire bundle under the seat and make sure all connections are good, especially the black with white stripe.

brake light: replace the bulb, turn key on and see if you have a running light, if so, hit brakes and see if the light gets brighter. if so, just a bad bulb. if neither works, check the socket for corrosion, then check the ground (black/white stripe). if running light works, but not the brake light, check the white wire, if the opposite happens, check the brown wire.

turn signals, if the right ones work, check the ground and the bulbs. left side power should be the black wire.

as far as headlights go.. same thing, check the ground, check the bulb, then check the yellow and yellow with white stripe wires. you should be able to jump the headlight to the battery or test between any ground and the yellow or yellow white wire to see if the circuit is completing and voltage is good.

edit: as the right turn signals work, it's probably a bad ground unless something went wrong with the left handlebar lighting switch.

If you fried the ignitor with a bad R/R than a few bulbs will be burnt also.

[djg42]

Thanks everybody,
I put new bulbs in the left side, the front one goes on but does not blink(stays lit), the rear one doesnt light up at all.
Im gonna try and check the wires today, hopefully i can make sense out ouf it

Why won't my bike start? I have the exact same problem on the exact same bike. Replaced the igniter and the R/R but it still won't start

Yeah, the petcock works good.

It's getting fuel and vacuum, good compression, but it's just not getting spark...
