First Problem (s) at 1,200 Miles

[proeasy]

I was on the same ride with Fast1, however my problem was not as fixable.

1. After a gas stop on the third day of our 1100 mile trip the engine would crank but not start. I could hear that the fuel pump was not priming and the nuetral light was flashing 3 shorts and on long flash. Checked the fuses and conections to no avail.

2. After the 2nd gas stop on the first day came to a stop and whole kickstand, bolt, and spring were gone. Never hit anything must have come loose.

3. My dealer is small and not to familiar with Husky's. I have heard of the following field campaigns for 08's: New Batter Tray, Upgrade to Ibeat software (I do not have the PU kit yet) Any other fixes out there I should know about?

Any thougts on the fuel pump problem. Called the dealer when this happened he was thinking a cranshaft position sensor.

BTW: Fast1 has the PU kit, I do not, we were both running 15t CS gears. During a high speed run at an abondoned WWII air base in the UP he hit 96 MPH, I would top out at 91. We both saw some orange specs in our mirrors. Another rider on a TE-610 out ran the orange bikes as well.

The flashing of 3 shorts and a long is a code for the problem. The dealer has these codes and they're probably available in the workshop manual. Since he mentioned crank position sensor he probably had the codes handy.

Edit...never found them in the manual.

Still think the dealer can diagnose on these.

From the Shop Manual

FUEL INJECTION SYSTEM
The fuel injection system consists of: fuel tank (1), electric pump (2), hose (3) and
injector (4). The fuel in the tank is pumped by the fuel pump and the pressurized
fuel flows into the injector installed in the throttle body (6). The fuel is injected into
the throttle body with a conical dispersion when the injector opens according to
the injection signal coming from the Electronic power unit (5) located under the
fuel tank.
The items to be considered for the correct output of the fuel in every condition of
use of the vehicle are the followings:
- Air temperature in the intake manifold;
- Engine coolant temperature;
- Atmospheric pressure in the intake manifold (in the current position and altitude);
- Throttle opening percentage;
- SMR: Vehicle rollover;
- Rich or lean combustion mixture (O2 sensor);
- Battery voltage;
- Sensors source;
- Current gear position;
- Pulse width of fuel injector;
- Ignition coil;
- O2 heater.
The diagnostic software "DIAGNOSIS SOFTWARE KIT" (see on pages S.3-S.4)
allows the check of the above mentioned parts in case of fuel injection system
malfunction.
The electric pump (2) is assembled in the bottom of the fuel tank (1) and consists
of rotor, magnet, impeller, brushes, control valve and relief valve. The ECU (5)
checks ON/OFF condition of the pump.
In order to remove the fuel pump, first it is necessary to remove the fuel tank as
shown on page E.23, then remove the six fastening screws (a); for the reassembly,
reverse the above mentioned operations (for the fuel pump check, please see
page S.5).

Operating instructions for the "DIAGNOSIS SOFTWARE KIT" on the fuel
injection system
Premised that the fuel injection system doesn’t need any programmed
maintenance, the Diagnosis Software Kit code no. 8000 A9634 allows to effect
the check of the components of the fuel injection system in case of malfunction.
The neutral green warning light shows the malfunction, with the ignition key in
ON position and the right commutator in RUN position, in the following way:
a) With the GEARBOX NOT in NEUTRAL position: the warning light FLASHES
INTERMITTENTLY.
b) With the GEARBOX in NEUTRAL position: the warning light IS INITIALLY
CONSTANTLY ON then it FLASHES TWICE IN RAPID SUCCESSION then
returns TO BE CONSTANTLY ON. This cycle repeats itself.
The "DIAGNOSIS SOFTWARE KIT" (A) consists of:
- CD containing "Diagnostic Tool" Software, User's Guide (PDF file), Operation
Manual (PDF file);
- User's Guide handbook for the Software Use;
- Operation Manual handbook;
- Connecting cable PC-ECU interface connector.
After DIAGNOSIS SOFTWARE loading, according with the User's Guide
instructions, proceed as follows:
- remove the front headlamp holder as shown on page M.30;
- remove the plug (B) from the ECU connector interface (C);
- connect the cable (D) of the kit to the connector (C) and to the serial port (E) on
PC;
- turn the ignition key (F) in ON position then place the R.H. commutator in RUN
position;
- start the "Diagnostic Tool" Software previously installed, then carry out the
controls.
If the throttle body (H) will be removed and/or replaced, it is necessary
to adjust the T.P.S. again selecting the options "T.P.S. Idle Adjustment
Command" (page 32 on Operation Manual) and "Feedback
Adjustment Command" (page 29 on Operation Manual). See fig. 9-3-
4 on page S.4 for the "Feedback Adjustment Value".
The components of the fuel injection system that can be checked
with this diagnosis software are the followings:
1- AIR TEMPERATURE (Air temperature in the intake manifold);
2- COOLANT TEMPERATURE (Engine coolant temperature);
3- ATMOSPHERIC PRESSURE (Atmospheric pressure in the intake manifold
in the current position and altitude);
4- THROTTLE POSITION
5- TILT SENSOR (SMR:senses rollover of the vehicle)
6- O2 SENSOR (Senses rich or lean combustion mixture )
7- BATTERY SENSOR (Battery voltage)
8- SENSORS SOURCE (It supplies energy to the sensors)
9- GEARSHIFT POSITION (Current gear position)
10- INJECTOR (Pulse width of fuel injector)
11- IGNITION COIL (It accumulates energy and discharges said energy to spark
plug)
12- O2 HEATER (It warms the O2 sensor to a temperature suitable for the sensor
to give stable output)

This diagnosis software allows, besides the identification of the
malfunctions in progress, also the memorization of those that are
already occurred and that have been eliminated: for these last ones
it is possible to effect the cancellation, following the instructions of
the Operation Manual (page 29).
The ECU memorizes the number of the engine running hours (with
tolerance: + or - 1 hour) and, in the case of the first equipment, the
identification numbers of the frame (VIN) and of the engine (Engine
No.) of the motorcycle. In case of replacement, the new ECU will only
show the number of engine running hours.
NOTES
The NEUTRAL green warning light comes on ONLY when the ignition key is in
ON position and the R.H. commutator is in RUN position.
The front-rear lights and the instrument display will come on when the ignition key
is in ON position.
The functions controlled by the L.H. commutator and the rear stop light can be
selected ONLY when the engine is running.
For the fuel pump and relays check, please see on pages S.5 and S.6.
Adjust item

Fuel pump check
Remove the pump as shown on page S.2.
- A: reserve sensor
Check that in the reserve sensor has not remained any gasoline therefore set
the meter on "Impedance" position and effect the reading on the cables BLUE
and WHITE. The value will have to be: 1.3 KOhms (+/- 10%) to 20°C.
- B: pump working
Connect the RED (+) and BLACK (-) cables to a 12V stabilized feeler then
check that the fuel pump runs.
Don’t continuously effect this last check for more than 3 seconds.

Relay check
Remove the saddle and the the fuel tank as shown on pages E.15-E.23. Remove
the relays (1) located on the frame, R.H. side (no. 1) and L.H. side (no. 2).
A: set the meter on "Impedance" position and check that the exciter coil functions
properly; the value will have to be: 80 Ohm (+/- 10%) at 20°C.
B: set then the meter on "Continuity" position and check that the circuit is open.
C: using a 12V stabilized feeler for the coil and check that the circuit is closed.


Found this about the FI system in the shop manual
IMPORTANT: Functions of the GREEN warning light (4) “NEUTRAL” in case
of FUEL INJECTION SYSTEM malfunction (contact your local HUSQVARNA
Dealer)
a) With the GEARBOX NOT in NEUTRAL position: the warning light FLASHES
INTERMITTENTLY.
b) With the GEARBOX in NEUTRAL position: the warning light is initially
constantly ON then it FLASHES
TWICE IN RAPID SUCCESSION then returns to being constantly ON. This
cycle repeats itself. After eliminating the malfunction, the warning light (4)
returns to its normal operation.

I don't see anything in the shop manual about a crank sensor. Next time I'll have the shop manual, on CD, with me. It is available at Halls for ~ $10.

If I recall correctly both our bikes had an issue after we stopped at a fuel stop and were away from our bikes in the gas station. Upon return they wouldn't start. They did run fine until they were turned off and re-fueled. I'm wondering if you just have one of the FI sensor connectors unplugged or broken such as I found on mine. I would very thoroughly look at all the sensor connections to ensure their integrity. What is more puzzling is that one stop after yours failed, mine did. Is this just a coincidence?

As was mentioned the Husky's pulled away from the orange bikes on acceleration and top speed. I know that with the 15 tooth my bike is not near as quick nor as fast with the 13 tooth.. I was however very surprised at the performance of the TE510 with the stock can and fuel mapping. Much better than I expected however I've never had the opportunity to try it since I installed the PU before my first ride. On an early ride this year I experienced the same thing when running against a orange 690..

When I had the stock mapping and exhaust on my bike I noticed that a lot of times it would run awful, backfiring, stalling etc. Once everything was disconnected and the Arrow exhaust was installed, it ran 100% better.

Dropped it at the dealer this morning. Hope to hear something soon. Thanks for the input.
