Will not start, no lights

Hello,

Yes, it sure sounds like it. All the electrical connections of your vehicle must be clean, tight, corrosion free, and making good metal to metal contact. Let's face it, vehicle's are becoming more and more dependent on electronics and sensors in order to operate. What is the language that these components speak? Electricity. That is how the "computer" gets it's information from all the sensors, and how it makes decisions and then outputs information to the components it controls. Without good, healthy battery cables and connections to the battery how can your vehicle's electrical components, which operate the whole vehicle, work? They can't. My advise here is to take your time and purchase the correct parts, and do not cut corners here and make these connections impeccable. Please get back to us with how everything turns out.

Thanks,

Hello again,

Yes, you should. Corrosion, anywhere, in an automotive electrical circuit is classified as unwanted resistance. Unwanted resistance, in fact any resistance, does just that. It resists the current, or electrical flow, and forces the electricity to use voltage[electrical force or pressure-similar to p.S.I. In a water hose] to overcome the resistance. When the electricity reaches the component it is intended to power, there will not be enough voltage to power the said component, and it will not work properly. A great example is a headlight with corrosion on the fuse that protects the headlight circuit. The voltage that was intended to illuminate the headlight was diminished by the unwanted corrosion on the fuse and the electricity had to use voltage to overcome the corrosion. When the electricity makes it the headlight it turns on, but is very dim. This is caused by the corrosion on the headlight fuse.

Every electrical connector, fuses, ground needs to be clean, tight, corrosion free, and making good metal to metal contact. You can purchase Dielectric grease at any auto parts store for a couple of bucks and it will inhibit the formation of corrosion and is an electrical conductor.
