Runs with no lights

Most of the time this symptom indicates a low battery that needs to be charged or replaced.  If you don’t have a voltage meter handy, a quick and easy test to verify this is to plug your charger into the wall and connect the Vexilar at the same time (you will not hurt anything by doing so).  If your Vexilar comes back to life when the charger is connected this confirms your battery needs to be charged or replaced.   

To properly check your battery with a voltage meter:

1.     Fully charge the battery
2.     Disconnect the charger
3.     Put a load on the battery by running the Vexilar for at least 10 minutes
4.     Connect your voltage meter to the battery

No battery is the same so it’s hard to put an exact number on what determines a good verses a bad battery.  A voltage reading around 12.5V (give or take a few tenths of a volt) would be considered a good battery.  A battery reading lower than this does not mean it’s unusable, it just may not last as many hours as battery at 100% capacity.

Depth is off or moving

If your depth is rocking back and forth the motor is probably failing.  If you wish to get your motor replaced send the head unit into Vexilar for repair.  Replacing a motor typically runs about $80.00 parts, labor, and shipping included.

            We’ve never seen a unit read the wrong depth unless the motor speed was off.  Remember the environment you are plays a big role in what you are seeing on your flasher.  A thick weed bed for example, can cause the depth to appear to be at the top of this structure

Depth is rocking back and forth

If your depth is rocking back and forth your motor is probably failing. If you wish to get your motor replaced send the head unit into Vexilar for repair. Replacing a motor typically runs about $80.00 with parts, labor, and shipping included.

Unit makes a growly sound

It is normal for there to be noise coming from the unit.  There are brushes riding on metal slip rings and a motor spinning at about 2400 rpms.  There is slight noise variation between units.  This is normal. 

In the case there is an abnormal noise issue it is most likely coming from the motor and not the brushes as most commonly believed.  An older motor may make more noise than when it was brand new but may not affect the function of your unit.  If the motor is failing it usually is accompanied by your depth moving or rocking.  If you feel you have an issue you can send the unit in to Vexilar for evaluation.  Motor replacements typically run about $80.00 parts, labor and shipping included.         

Doesn’t turn on

Most likely there is an issue with your battery, there is a bad connection, or the motor is failing.

Checking Your Battery

 If you don’t have a voltage meter handy, a quick and easy test to check your battery is to plug your charger into the wall and connect the Vexilar at the same time (you will not hurt anything by doing so).  If your Vexilar comes back to life when the charger is connected this confirms your battery needs to be charged or replaced.

Connection Issue

For a connection issue check for breaks in the power cord visually or by wiggling the wire while the unit is running to see if power cuts in and out at any point.  Also check for loose connectors or corrosion at the battery terminals.

Motor Failing

If the motor is failing it’s best to send it in to get it replaced. Typically it costs around $80.00 (parts, labor and shipping included) to replace a motor.  Other signs of a failing motor is seeing your depth move around, inconsistent motor speed, or a very loud growling noise.

Unit makes a loud screechy sound then goes away

Don’t worry this is normal.  When these units are brand new you have square brushes riding on round slip rings.  The brushes need time to round out and seat properly onto the slip rings.  Once seated properly this will happen less frequently.

Lights are dim

Most of the time this symptom indicates a low battery that needs to be charged or replaced.  If you don’t have a voltage meter handy, a quick and easy test to verify this is to plug your charger into the wall and connect the Vexilar at the same time (you will not hurt anything by doing so).  If your Vexilar comes back to life when the charger is connected this confirms your battery needs to be charged or replaced.

Lights on older FL-8’s or FL-8SLT’s were dimmer compared to newer units.  If you have performed the tests stated above with no change in light brightness it’s probably just how they are. 

It’s also possible there is an accumulation of brush dust on the slip rings and lens. You can send the unit into Vexilar for a general cleaning or you can do it yourself.  Look under “Manuals/Instructions” in “Learning Center” for instructions on slip ring cleaning. Typical cost of a general cleaning is $20.00 labor plus $10.00 shipping.

Lights have black lines “chattering” around in them

This is probably due to an accumulation of brush dust on the slip rings. You can send the unit into Vexilar for a general cleaning or you can try and do it yourself. Look under “Manuals/Instructions” in “Learning Center” on our website to see instructions for slip ring cleaning. Typical cost of a general cleaning is $20.00 labor plus $10.00 shipping.
