Not advisable on cars with ECMs, which the Sentra ECCS obviously has. Doing so may introduce electrical surges and could cause more damage. Much more if indeed the alternator or RR is defective and is sending out unregulated and/or noisy electricity.

Think of the battery as one giant capacitor.

Beyond the hands of a good electrician, the Nissan CONSULT should be able to tell you if the charging system is out of spec.
