Exact machineDo not buy parts from a broad answer.
Your exact machine, year, trim, VIN when needed, and the part number are required before treating any battery, relay, starter, or cable as the right fit.
Safety boundaryStop when the answer stops being enough.
Stop and get hands-on help if cables heat up, insulation smells burnt, the starter stays engaged, or the machine could move unexpectedly.
