Hey guys..whats the average life you've gotten out of your alternators? My original went a good 85,000 miles...since then I've replaced it with a Autolight or whatever that orange box fawker that comes from Kragens/Shucks.....has a lifetime warranty but in the last 13,000 miles I've had to have that SOB swapped 3 times. Even though the replacements are free...im tired of dealing with it. The nissan dealership out here wants 270 for a brand new one...im wondering if its worth it. What type of experiences have you guys have with Alternators?
