Buyer Questions
How do I know if it is battery or alternator?
If a charged battery repeatedly drains while driving, alternator output is often the issue. Bench and in-vehicle tests confirm quickly.
Starter clicks but does not crank. What next?
Check battery state, cable connections, and voltage drop first. Then confirm starter draw and solenoid operation.
