I think I have a bad alternator. I've done the voltage checks and I get 12.8 with engine at idle and 12.4 with engine above 1500. Yes, lower with engine at higher RPM...strange. In any case, I'm looking at alternators and I can get one from the dealer for $300 or so but I found this on Amazon and eBay for $69....big difference and it seems to be identical to the unit I need...any comments or opinions on whether the cheap alternative is worth a risk. Here's the link to eBay. https://www.ebay.com/itm/New-Altern...1-SAEJ1171-Certified-for-Marine-/282910828901.
Any response would be appreciated on the alternator and also any idea why the alternator is putting out less voltage at higher RPM would be appreciated.
Thanks!
