Acewell NTC Input converter

The Acewell IVR-04 is an LED converter with single output. This adaptor replaces the bulb in either a motorcycle low fuel level adaptor or the battery light on a BMW Boxer to allow an LED to be used to show the low fuel or battery warning instead.

The adaptor can also be connected to an Acewell fuel gauge in RES mode to display low fuel on the LCD.

IVR-04 has 1 output which pulls -ve when the bulb would normally be illuminated. To connect to a RES mode fuel gauge you connect -ve If using one of the LEDs then check if it needs to pull +ve or -ve on the wiring diagram for the LED.
