Suzuki GT380 - Power to the coils

[miked914]

Hi Everyone,

Does the wire from the rectifier (either Orange/White or Yellow/White) that goes directly to the coils provide 12 Volt power for starting/running? Or do I need to run a separate lead from the battery to the coils?

Thanks!

The wire from the rectifier goes to the main battery power lead (red) - which goes to the ignition switch and comes out as orange to the kill switch, then orange/white to the coils. You need a battery to run the 380, not just from the rectifier, as the genny doesn't work without some battery power to the excitation windings.
If you just run a wire from the battery to the coils, you'll need a switch as well unless you intend running the bike for ever without stopping the engine.

Thanks Alan,

I will be running a battery but will not be using the handlebar kill switch. I will have a kill switch wired in though probably under the seat.

Maybe the better way to phrase my question is, can I put a switch in-line on the Yellow/white wire from the rectifier that goes to the coils and use that as my kill, and will that provide power to the coils for starting and running OR do I need to run a lead from the battery to the coils as well?

I know that the red lead from the regulator goes to the battery for charging purposes so I'm all set there.


Thanks!

The lead from the rectifier is dead unless the engine is running, so you need a battery +ve feed to the coils to get sparks.
The beauty of the kill switch on the right bar, is that if you need it, it's at your 'fingertips' rather than under your arse if you need to switch off when crap happens, you don't need to take your hand off the bars when your arse is trying to bite onto the seat if you know what I mean.

Not sure what the yellow white wire comes from, it isn't on my diagram.
Hope 'arse' isn't a profanity in the US or I might be sent to hades or whatever!......
It should translate as Ass - which to us is a donkey, but never mind.....
Two nations divided by a common language is all.

PM me your email addy and I'll try to help, or send me a copy of your wiring diagram as your description seems strange.
See your PMs.
