    Anyone ever had this happen?

    Yes, I am full of questions(and b.s.). I had to have my alternator replaced. I went to my mechanic and,long story short, ended up at the stealership because my alternator died. They say it was my LOC(navone N-RHL2) causing a spike and frying a 130amp alternator. I had it wired per the directions with one deviation, the power was going to the constant hot instead of the switched power, does their theory seem reasonable? The only other issue concurrent to this was the crimped up wires in the door jamb that were causing a whine. Do you think the shorting of the wires caused an electrical feedback coupled with the wiring from the loc to cause this? Could this have all combined to fry the alternator?

    Thanks,
    Al

    Yeah, i havent read anything to that effect. I just don't think the loc draws enough amperage to do that, but go figure.

    Don't forget that the LOC is also the thing telling your amp to turn on and off. With the LOC staying on all the time, your amp(s) may also.

    It doesn't seem likely to me that the LOC fried your ALT - unless there was a short in an un-fused section of the +12 power wire you connected to the battery - but if that was the case, you would know it (would have melted the wire). I have seen high power amps blow the diodes in the internal voltage regulator of the alt. I have also seen where reverse discharge of large capacitors can blow the diodes. I would examine your system carefully for other possible causes just to make sure you don't wind up with another fried alt. What year-model car do you have? What size/type amp(s) are you running? What symptoms were you experiencing before the alt blew?

    They will blame ANYTHING not oem in the car so they wnt have to repair it under warranty.

    One time I was installing a car phone (yeah, I'm old) and, as I was going over possible microphone locations with the customer, I noticed that the headliner just forward of the sunroof was cut wrong leaving a slight gap that the trim didn't cover. I pointed it out and the customer told me that he had the car for a couple of weeks and never noticed it. He told me to go ahead and do the install and he would carry it back to the dealership later. A week or so went by and the customer stopped in to pay his bill and he told me that the dealership tried to claim that his cell phone installer had cut the headliner. The customer called BS because I had pointed it out before I even started, but the mechanic still refused to fix it until a few calls to the regional manager set things straight.

    It's a 2005 scion xA. I have a rockford 250x and a hifonics Mercury X(2x50), both of these are not really high-power amps, maybe 340 total RMS. I went ahead and disconnected the power in for the Navone LOC so, that way, I can at least rule out what these jackasses at the dealership are saying. BTW, I spoke to my mechanic and a car builder at the local parts store and they called BS also. They had never heard of this happening the way the stealership describes. I had been having a "blip" when I would drive the car intermittently for several months when I had a jvc radio with the same equipment. I had installed the radio with a generic harness that had had some of the wires clipped but they had been capped off with butt splice connectors and I didn't think I had any issues. The way I knew my alt was going was that the radio would sound as if I had a bad FM connection...It...would...go...in...and...out...li ke...this. I never did smell any burnt wiring or anything of that nature. I pulled the radio and didn't see any thing of any concern, but, that being said, I am going to reinstall the radio with a new harness and use a remote out from the stock radio. We'll see what happens.

    Sounds like a good plan. Good luck.

    ok, well, couple of things. As it turns out, it was a 90 amp alternator my mechanic used not 130, but that being said, i still don't buy the nimrod's story. But, i did re-install the radio with a new, unhacked harness. I also took the wiring from the doorjamb(the wires were shot-thanks to everyone who helped catch that) and put some crossovers in the door and used factory wiring in the door so nothing gets pinched.) so, we'll see what happens. From here, the only thing left to do is take it to an electrical systems specialist. Thanks for the help and info guys.
