QuestionI have a 1982 Yamaha Virago 920 which has a computerized monitor system. Part of the display has diagnostic warnings for kickstand, brakes, oil, headlight, taillight, fuel, and battery. I have just replaced the battery with a sealed type which does not have a hole to insert the sensor for this and the computer system displays a battery warning.
The battery purveyor indicates that the sensor should be disabled but fails to mention how. There is nothing in the manual and I couldn’t find any instructions with a check of the internet, can you help?
AnswerLee,
-the sensor has to be fooled into thinking
it is attached to the battery.
-Get a 2000 ohm, 1/2 watt resistor, available at
most electronic parts stores.
-Get a test light and find a power source that
goes off when your ignition switch key is off.
Possibly your fusebox or taillight power or such.
-Attach the sensor wire to the power source with
the resistor between.
-The sensor wire to the resistor to the power, like that.
-If all goes well the warning light should go out.
-All we are doing is simulating what the sensor
does, which is send a voltage reading from the
battery to the computer.
-The resistor just cuts the voltage down a bit
because the sensor is used in only the third cell
of the battery which is low voltage.
