Stator pickup 2 wires ? By rob63 (Read 3,900 times)

[rob63]

I should know this and I`m kicking myself at the moment.
Our Sym fleet has the normal 3 wire multiplug from the stator for lighting and earth wires. But there are two separate wires from the pickup, one is obviously the trigger, what is the other one ? Is it a + feed to the pickup ?
This is an AC system with a 6 wire cdi, but no killswitch so I`m presuming the kill wire goes to the ignition switch which shows earth with the switch off. Should it be dead with the switch on or show + ?

if it is black/red like this one then it is the power wire to the cdi www.nycscooterparts.com/#!product/prd1/1565893155/single-phase-6-pole-stator

Rob, I think it is two wires for the same ungrounded pickup circuit. This is from a two cycle Hyosung on another thread but the stator looks exactly the same as what you described:

DAMN!! Wrong image.....hang on.....damn chickens....here it is:

What SYMs are in your fleet? JR or myself might be able to find a specific chicken...I mean diagram. The way I see that it's one AC current running through the CDI. I mean, what's the difference if you ground the circuit at the CDI and it comes back through the case to the pickup coil? It's still an AC circuit. The kill runs to switch in this diagram....wide variance there as you're aware. Kill, in my opinion, would be earth with switch OFF. Rich

Cheers lads, I had a quick look at the forum this morning then went to work. I`m not sure why I thought it was a 2 wire pick up, of course the red/black is the power to the cdi.
Unfortunately I was busy all day so only managed 1/2 hour on this scoot, looks like the kill wire is showing earth with the ignition switch in both the on and off positions so I`m suspecting that`s where my 'no spark' problem stems from. I tried another ignition switch, stator, and cdi to no avail, so looks like I`ve got a short somewhere in the loom maybe. I even snipped the kill wire but it didn`t make a difference.

If it's not the kill......Maybe come back to pickup?........CDI ground? Floating balloons.

I took some values in ohms and voltage off the stator and cdi, but left my notes at work. I`m hoping to spend a lot more time on it tomorrow.

Check your ground from the motor to the frame if you snipped the KILLWIRE.

Cheers Alley. We eventually changed the loom on this one, still no joy. Tried the new ignition switch as well and everything worked. So I`m thinking it was a connection problem either on the earths or on the multiplug for the ignition switch.
We did clean the earths and all the loom connectors previously but who knows, just glad it`s working again and back on the fleet.
If anyone has a wiring diagram for a Sym Jet4 125cc it would be useful, Sym don`t seem to include one in their manuals.

We've got some stuff that's close in the library you might want to take a look. JR has some stuff but I didn't see a perfect match. When JR gets back from ball practice I'll ask him and see what he thinks is applicable to that bike. Rich
