 Posted: Wed Jun 18, 2008 7:11 pm Post subject: Alternator Warranty Data Point - Rebuilt vs. New |
 |
|
Just a data point I thought might be interesting. I recently had the opportunity to review warranty rates on several of the major rotating electrical rebuilders for alternator warranty returns through autopart stores. Low number was 9.6% and high was 18%. This includes wholesale as well as retail sales with no data as to specific cause. The manufacturers all report "true" warranty rates at 5%- 8% on product tested after it was returned. Warranty on New Alternators was running 5.6% so they were substantially better. No numbers on the "true" rates for New product but I would think it about 3%. These numbers are very much in line with historical rates we saw several years ago. Also should note that warranty rates do vary considerably by specific application and these numbers apply to the category and not a particular unit.
It is interesting that while the technology involved in the rebuilding and testing processes has improved over the past few years, the actual return rates have not reflected the benefits of better processes. ( I attribute that to "trial and error" troubleshooting on the retail side.)
I would interpret this to say that if you are using an automotive alternator, the odds of a failure in the first few hours of operation are about double for rebuilt versus new and 1 bad rebuilt unit out of every 10-15 should be a normal expectation. For our purposes,….. buy new if you can.
It would be very interesting to know what the return rate and actual failure rate is on B&C units after they have done all the extra tuning, balancing, etc. Maybe Bob could get that number for comparison?

My personal track record is nearing 600 hrs on 2 B&C L40s (2 planes) and they are both still kicking coulombs with nary a hickup!
