Common questions
Can corrosion alone cause a no-start?
Yes. Heavy buildup can block current even when the battery is fine, and cleaning may fix it.
Why is the positive cable pricey?
Some are built with fuses, junctions, or long runs to the starter. Those molded ones cost more than simple cables.
Does a bad ground cause problems?
Yes, it can cause odd electrical symptoms, dim lights or a weak start. Ground straps are inexpensive to replace.
