My Tach Won Light Up?
1.) Check the power to the White (illumination) wire. This is your power input to the light and the amount of power will vary depending on how and where you have it hooked up. The lower the power, the dimmer the light and the higher the power, the brighter the light. A common range is from 6 to 14 volts. 2.) If your tach features LED lighting such as Cobalt, C2, or NV models, and you have confirmed power to the White (illumination) wire, please visit the Ask A Question or Contact Us pages to communicate with our Tech Department. 3.) If your tach uses a replaceable incandescent bulb (check your instructions), inspect the filament of the bulb and replace as necessary. Very few of our tachometers use an incandescent bulb that is not consumer replaceable. If you believe you have one of these units, please visit the Ask A Question or Contact Us pages to inquire about having the bulb replaced.
