FAQ (Frequently Asked Questions)

 

Q

What wiring changes are required on my existing installation?

A

As well as running a wire to your alternator field terminal, you will need an ignition source to the ZM6 and a battery positive and earth.

Q

Will this unit work through a VSR (Voltage Sensitive relay)?

A

Yes. A good way to allow dual battery charging, sense off the house battery.

Q

Will this unit work through a diode splitter?

A

Yes. The ZM6 can compensate for the typical voltage drop over a diode bank, providing that the battery sense wire is on the battery side of the diode bank.

Q

Can you refurbish my alternator and convert it to an external regulator?

A

Yes, we do this regularly for clients.

Q

Can I modify my alternator?

A

Yes. It is a matter of running a field wire to the appropriate side of the brush block.

The ZM6 N controls the earth side of the brushes.

The ZM6 P controls the positive side of the brushes.

Q

What is the difference between N and P switching

A

Certain manufacturers elect to switch the positive brush whilst the majority of others switch the negative brush, as a user you do not know the difference in an operational sense.

Q

Why does the RED LEDs glow slightly during operation.

A

As the voltage/temperature near the trigger threshold the LED will glow slightly, this is normal and nothing to worry about.

Q

There is an orange LED flashing on the inside of the unit?

A

This LED flashes with the onboard oscillator which will run when in Absorption mode, it is normal and for fault-finding purposes.

Q

What is the field LED function and will it indicate a blown fuse on the field line?

A

The purpose of the field LED is to indicate that the ZM6 microprocessor is outputting a field current. It is located downstream of the fuse so will NOT indicate a failed field fuse (5 amp)

 

Q

The unit is powered up and the system does not charge and there are no fault LED’s on nor is the field LED on

 

A

Push the clear button or reset ignition, a previous fault has shut down the system and requires resetting.
