Aftermarket Ficht DI Stators Miswired - A Field Service Bulletin from Lakeside Tech

[HiPeRcO]

Keywords: Virage TXi stator, Genesis DI stator, FICHT stator, Virage i stator, Polaris DI stator


I have had a number of customers that were having issues with their skis starting/running, even though everything checked/measured OK (EMM (checked/repaired by Lakeside Tech), Stator AC Volts good, CPS ohms good, etc). It turns out that a number of aftermarket stators are miswired out of the box (one or more pairs with swapped polarity) Since the EMM "stacks" the windings, POLARITY MATTERS. The toughest problems to solve sometimes end up being caused by putting a new part in with the assumption that it's good...


Attached are some pictures and color codes (AFTERMARKET STATOR), and the OEM wiring diagram. While I believe this information to be correct, your stator may or may not match, so caveat emptor. At a minimum I suggest you make a record of where you started from before you start swapping wire pairs around. (Swapping pins is easy, just carefully pry out the end cap (front of the connector) and then use a small screwdriver to release the pins).


Note that for the most part the aftermarket color codes correlate to a degree to the OEM color codes. (pins 2/11 seem to be the exception)


Hope this helps!

Great info. Thanx.

Checking Ficht stator for correct 12-pin connector coil wire phasing

-
How can I check to make sure JetUnit [Ficht stator connector] wiring is correct? ...

You could try this method.
I have not tried it myself (I do not have a Ficht engine here) but it should work



Link together all five red pins. Do not mangle or stretch the metal sockets with too-large copper wire. If you have alligator test leads, those could work well enough.

Connect your multimeter to the 12-11 pins (shown as light blue in my diagram). Set meter to AC volts, with 0.1 volt precision on 20 volt range.

Cranking engine long enough to get stable meter numbers, note the sustained AC voltage and the voltage range (highest and lowest meter readings).

Move the meter probes to the 10-11 pins (shown as pink).
Repeat the above cranking test for AC volts.

Continue testing though the 9-10 and 8-9 wire pairs.

You should end up with four AC voltage results.

What this does is show the phased difference in AC voltage output between stator coils.

On a correctly wired and operating Ficht stator, I would expect very small AC voltage differences for the 8-9-10 coil outputs, and the 11-12 pair.

I would expect just a couple volts AC difference on the 10-11 pins.

If you can run this stator phasing test and report back, these numbers might reveal an incorrect phasing.

Also, do the normal Ficht stator AC coil output checks and report those numbers.

Also check every Ficht stator coil for ohms to engine ground, None of the coils should have any connection to engine ground.

How do you know what the polaridy of the stator is ? I have been fighting with 2 polaris virage i all summer just happened to stumble onto this post yesterday and last night i went to put in a new stator into one of the machines and sure enough its a aftermarket one and found pins 2 and 11 and 5 and 8 in opposite locations from where you have listed them above. With the way it was recived and then changing the pins to the way you have them and still no change in the running of the machine as i cant get either of them to start.

I checked my own (OEM stator) and observed the following results:

8&9 0.24V
9&10 0.24V
10&11 3.2V
11&12 0.34V

Also, for reference
1&12 9.1VAC
2&11 9.3VAC
3&10 5.9VAC
4&9 6.0VAC
5&8 5.9VAC

Hat tip to @K447 for proposing this method

I performed this test on my 2004 MSX140 and got quite a difference between the pairs. Pairs 8-9 & 11-12 were close to each other; 9-10 was slightly higher; 10-11 was a lot lower than all the other pairs. If there is a large difference between the pairs is this an indication that there is a problem with the EMM?

Hopefully you performed this test with the stator unplugged from the EMM? If so you are only measuring the stator characteristics. If your voltages do not match the pattern above, then your stator is probably miswired (assuming that it is an aftermarket version).

I did perform the test with stator unplugged from the EMM. I checked that the wire colors pinouts matched the wiring diagram (attached file) at the 12-pin connector, and they did. I have not yet checked the other ends of the wires to see if they come from the correct location. Is that something I should check and verify?

To my knowledge it is not an aftermarket EMM, but I don't know for sure. Is there a way to determine if it is aftermarket or OEM?

Just for some more information if this helps, I also checked the VAC and Ohms of stator connector:
12 Volt stator Windings

• Pins 1 & 12: 0.8 ohms, 10.3VAC
• Pins 2 & 11: 0.8 ohms, 10.3VAC

45 Volt Stator Windings

• Pins 3 & 10: 0.6 ohms, 6.8VAC
• Pins 4 & 9: 0.6 ohms, 6.8VAC
• Pins 5 & 8: 0.6 ohms, 6.8VAC

All these values are higher than what the service manual states. Would this be related?

[HiPeRcO]

From what I have seen, the aftermarket stators have wire colors that are quite different from OEM. So if your wire colors match the OEM colors, it's most likely OEM. Your AC volts and ohms look good.

Thank you for the information HiPeRcO! I've been trying to diagnose my MSX140 for a while now. I've been slowly eliminating component issues. I'm currently trying to figure out why there is excess smoke coming out of the exhaust.

Attached is a very tidy way to short the pins together using solid 14AWG wire and a large wire nut. Be sure to deburr the wires to avoid damaging the connector sockets. Photo credit to G.Q. on Facebook.
