Introduction
The Autodiagger AD100+ is a handheld tester that is used to test and diagnose alternator charging
problems by replicating the digital signals from a vehicle’s ECU. The AD100+ tester can test an
alternator while it is still installed on a vehicle or on a testbench.
The tester can provide information on whether the alternator’s voltage regulator can communicate
correctly with the vehicle’s ECU and if the alternator responds correctly to the tester’s simulated ECU
input parameters.
The AD100+ can now be updated by NFC from a compatible Android mobile phone or by returning it
to Wood Auto for the update procedure.

Device Operation
The device powers on automatically after connecting power to the B+ and B- leads. The test subject
selection menu will then appear. The desired parameter is selected by pressing the and buttons
and conrmed by a short press on the OK button to enter the testing mode.
After pressing OK, the display will present the following information:
1. voltage of the tested circuit (large digits)
2. required voltage (small digits on the top of the display)
3. alternator load DF/DFM (%)
The green RC and blue M cables should be connected to the correct pins in the voltage regulator’s
socket. Some of the regulators may require connecting other signals (usually B+) with a separate cable
to operate correctly.
The blue M cable can be left disconnected when testing in COM mode.
In the testing mode, buttons and will change the required voltage value. It should be monitored
whether changing the required voltage causes a corresponding change in the alternator/regulator output,
and whether the DFM reading matches the actual state.
Press and hold the OK button to leave the testing mode and return to the selection menu.

i-STARS Testing Frequently Asked Questions
Can the device be damaged due to improper connection?
The device is resistant to connection errors from typical applications and voltage ranges.
Can the device damage connected units?
The device cannot directly damage any connected units, however the range of voltage sent to the
alternator is very broad and includes prohibited values (over 15V), which can result in electrical system
errors if the alternator is tested without removing it from the vehicle.
Can the device or connected units be damaged by selecting an improper testing function?
The only consequence of selecting an improper testing mode is the lack of a response from the
connected alternator.
Does the blue M connector have to be connected at all times?
Some alternators with a COM interface do not have an analogue DFM output. In this case, the M wire is
left unconnected.
Is it possible to use longer wires to connect units?
The device works with wires up to 5 metres long.
Can the testing device be used for 24V systems?
Yes.
After connecting the device, the display does not illuminate, show the start screen, or the
main menu – what should I do?
In this case, check if the testing device is properly connected, if the voltage of the connected system is
correct, and if yes, check the continuity of the connection wires.
How to store the testing device?
The device is best stored in a warm, dry place.
How to remove stains from the enclosure?
The device should be protected against exposure to any liquids or other substances that can penetrate
the enclosure. Stains are to be removed with a soft, moist cloth and a mild detergent. Do not use
naphtha, paint thinners, or solvents as they may lead to fogging of the display and damaging the coating.
Can the testing device be mounted on a testing table?
Yes, if it can be done without damaging the device’s enclosure. Do not drill any holes or put any screws
through the enclosure.
Why does the device display an error in the COM mode when the alternator stops
revolving?
Digitally controlled voltage regulators generate error information, displayed on the testing device, upon
detecting parameters outside the allowable range. In the case of alternator stoppage, this is a simply
a lack of revolutions error which should disappear once the rotor starts spinning again.This type of
behaviour is standard and conrms the alternator is working properly.

18
Why does an alternator with a COM interface start working only after I change the
required voltage for the rst time?
This is due to the alternator voltage regulator function. This type of behaviour is standard and conrms
the alternator is working properly.
Can the testing device be used to test alternators with a F1 – F2 connector?
Such alternators work with an external voltage regulator and require a different testing methodology.
