Alternator Question
|
Bronze Member Username: NikoncdPost Number: 48 Registered: Jul-05 | When is it important to get a new alternator... like how big of an amp (generally) do you think warrants a new alt. I can't find the HOT rating on my stock mazda3. My friend just threw a deal at me on an Arc Audio 1500XXK, but I see it draws alot of power and is an A/B class amp - would I probably need a new alt even if I didn't push the amp - prolly just a 400-500watt load? |

Bronze Member Username: NikoncdPost Number: 49 Registered: Jul-05 | yeah its an 05... so 100amps should be a number fairly close you think? hmm, well yeah I guess if my lights start dimming its a signal. Eh I was hoping I could just use stock until I would have more money, but I guess it would hurt my battery to continue if my lights were dimming. |

Bronze Member Username: NikoncdPost Number: 50 Registered: Jul-05 | more research... sad results. part of an MZ3 forum, and found out that it is impossible to replace the alternator, and only a solution is to upgrade to optima batteries, upgrade big 3, a cap (more of a band-aid), and then of course a second alternator. They mentioned it was rated at 90 amps, so thats disheartening too... I wish I had known this before getting the car, but obviously at the time I wasn't think about my future car stereo. Hopefully as you mentioned, with me drawing only 500 watts, I should be fine with amp of that size. I saw that someone else here on the forum was interested on getting an MZ3, hopefully he'll read this although the car is a dream and it probaly still wouldn't have effected my decision. |

Bronze Member Username: NikoncdPost Number: 51 Registered: Jul-05 | wow, thats great to know rick! I'll prolly hit up one of those batteries though, no harm. But great to hear your able to run 1600 with a stock alt!  |
