Product Questions

My Defender has a 100amp alternator, will it burn out this system rated at 85amps continuous? I was planning on installing a 140amp alternator as well, is that not an option?
Question by Steve
Your 100amp alternator should be fine with this product. However, we would recommend contacting National Luna regarding the 140amp option you're considering. Thank you!
Answer by Front Runner
Can this be used on a secondary battery to start a 3.0L v6 if the main battery goes dead?
Question by Raymond
Raymond,

Yes. If your battery dies, you can activate the solenoid from the controller inside your vehicle, and then start your vehicle off the secondary battery.

Best Regards,
Bryan
