| TF2001 Traditional "Midwife" |
 |
|
|
This Monitor is designed to mate with a traditional three-pin flasher relay to add a monitoring circuit and additional terminals, effectively converting it into a four-pin "caravan" flasher relay.
The diagram below illustrates how it is fitted.

The monitor measures the current coming into the flasher relay from the battery. When a trailer flasher lamp is operating in addition to the normal vehicle flasher lamps this monitor detects the extra current and emits a signal in its tell-tale output terminal that causes any panel lamp or buzzer connected to the tell-tale terminal to flash or sound.
The particular advantage of this device is its extreme ease of fitting. It has the disadvantage, however, that it does not fit in all vehicles. Its sister device the "Clone" adaptor TF2100 more universal and almost as easy to fit.

Panel lamp does not work
Check all connections
Make sure the connection to any panel lamp or buzzer is properly made.
Refer to the sketch.
Check that all vehicle and trailer flasher bulbs are working.
Check that your earth is a genuine earth. |

|
Panel lamp works when no trailer or test board is connected.
There may be more than two twenty-one watt and one five watt bulb on each side of the vehicle flasher circuit. If this is the case, use the TF2100X, which is pre-set to accommodate extra bulbs
If you are not sure that this is the case, try another Midwife. Sometimes the tolerances of the vehicle and the monitor coincide to cause an incompatibility. A new Midwife may work on that vehicle.
