650 has new stator ,, no spark

Hi Folks
I was the guy who asked for advise about the Fe 650 with no spark a couple of months ago. I recieved the bike from a fellow who sent it to a bike shop to have it looked at , because it had no spark. They told him it needed a new ignition switch which they ordered and installed. Again no spark so it sat for 8 months with no one taking time to look at it. He dropped the bike off to me and I tested everything I could and with all the values being low ordered a new SEM stator. I installed it and we have no spark. The owner is getting ugly and I am not certian where to look now. Does anyone have a suggestion or a neat way of chasing down the issue here.
Thanks in advance. Bearbuster

Have you tried "the doc" under electrical?

Bearbuster,
Did you get the correct part# stator from Husaberg?

I believe it is the correct as I ordred it from a reliable dealership. It appears the same and I even tried a unit from a KTM which fits the same and has the same test values. Nothing!!
I will look at the Doc and see if I can make some sence of it. Thanks JIM

I have been digging into this unit and find the wiring a mess. There are wires missing and wires broken and repaired with crimp on connectors so there is a possibility of corrosion.
Does anyone know if it is possible to only hook up the ignition wires and leave the charging system dissconnected for testing purposes only or does it supply any power to the coil or CDI unit???
Also if it is the CDI unit does anyone know if the replacement unit has to be an exact replacement or will a unit from another model work. I am asking this because by the time I order that coil CDI unit I will have over $1000 into this guys bike and I am still not sure what the problem is,(that is no labour). I have a 1997 Fe350 and I love it but this 650 is making me crazy. Thank again guys JIM

Hi,
all you have to do is connect the three wires from the stator to the ignition coil and if both are good it should produce a spark.
What year is the Husaberg?
If it is pre 99 the LC4 coil will work but I am not sure if the ignition curve will be the same, can you give me the numbers off the coil.

Hi Sparks
It is an 03 I believe. My understanding is he bought it in 04 and it has been a great machine so far. I am unable to get a hold of him at this time to confirm this but here are the numbers from the coil.
ICU 10
855-191-12
250290-01
and on the back side there is a paper sticker that reads 010624
Does the black wire of the coil need to grounded or attached to something in order for it to work. If so where does it attach. The coil was just sitting on the top of the head when I got it. Thanks JIM

The first thing I suggest you do is to obtain a single line wiring shcematic, available here in the downloads section, or from the Husaberg.se site. I believe the ignition was unchanged from 2002 to 2003. Look in the owners manual in section 12. There are a few different wiiring diagrams, the main difference here is whether or not the bike you are working on has turn signals or not.

The first thing you should try is disconnecting the orange wire at the coil, this is the kill circuit, or grounding circuit for the ignition coil. Disconnecting this wire at the coil and safing it up will isolate the entire ignition grounding circuit from the coil and eliminate that problem if there is one there.

According to the one line you should have the black wire from the ignition coil grounded. They changed a few things between the 01 and the 02-03 models, on the 01's there was a multi tab grounding bus that was held on by the bolt that holds the rectifier and voltage regulator to the frame. Your's might be different, but the length of the wire should help you figure out where it goes. The grey wire is for the high low switch and can be disconnected or opened. In fact the replacement coils no longer have the grey wire, at least the last one I bought didn't have it. And you should probably ground the blue wire coming from the generator to keep the ground refference the same between the stator and the ignition coil. You can leave the yellow wires disconnected and safed up for the time being. Did you test the spark plug cap??? It should read at least 5 Kilo Ohms. I'm also assuming that you have tried different plugs to eliminate that possiblity.

In the downloads area there is a section called manuals & documentation, look for the hard start guide and download it, extract it, and open it with a pdf reader. http://www.husaberg.org/index.php?modul ... lay&lid=16 Here is a step by step process for determining your ignition system problem.

As far as your part numbers go, your coil should be a 250310-01 according to the 03 owners manual. And according to the 2002 parts manual your coil would be correct 250290-01. It appears that the part number for the lower ignition on the 2002-2003 models stayed the same with a part number of 250285-01. It appears from the parts manuals that the lower ignition IE stator and rotor are the same and only the cdi unit is different from bike to bike as it relates to the displacement in the 2002 to 2003 model year..

Hope this helps,

Hi Dale "E" "O"

I tested the new stator I recieved and do not like what I read.
It tests wrong for the bike.
Green to Black tests 166 Ohms Kicking it tests at 2.5-2.6 VAC ( voltage correct)
Red to Black tests 2888Ohms Kicking it tests at 34-36 VAC ( voltage reads correct)
Coil ( less cap tested) 3046Ohms
Cap tested at 5.34 K Ohms

The old unit I removed because it tested low
green to black 165.3 Ohms
red to black 2244Ohms If I reversed the leads on the meter it tested"0" Ohms. I do not understand unless there is something different inside this unit which only allows power to flow one direction????
I cannot understand what those other guys could have done to have blown out everything. They were to replace the ignitions switch only. That was 8 months in the doing.
Thanks for your time Dale I really appreciate the help I have recieved. JIM

Jim,

Install it and start it!

If you are concerned about the Green-Black kick voltage, try it again with the Max Hold button engaged on your multimeter and kick the snot out of it 5 times in a row fast with the spark plug removed .

I'll bet you get 3 or more VAC.

It will run....

Regards,

Joe

tried it

Hi
Well I installed the new stator and it does not produce spark. Must be the coil eh!!!!
Is there any used ones out there. Thanks for you help JIM

You should have 2 black wires coming from the coil. One with a spade connector should be earthed. The black with bullit connects to the black from the stator and obviously green and red from the stator connect to green and red on the coil.

The other wire you need to make sure isn't mistakenly earthed is the orange wire - this is the kill switch wire - if it is earthed you will have no spark - so check continuity there.

I do have a spare second hand coil knocking around if you really need it. It is a 400 coil but would work fine - it's one of the typical 650 "upgrades" and came of my old 650.

Cheers,
Simon

used coil

Hi
How much would you want for the used coil ?
I have to get together some figures for the owner.
Thanks JIM
