Introduzione

This guide provides instructions for replacing a fluorescent light ballast and may not reflect different florescent light fixture designs. Intermediate multimeter knowledge is recommended to safely measure and confirm voltage, rewire the ballast, and remove electrical components from the ballast. Please contact an electrician if you are unsure what to do or do not feel comfortable proceeding.
