Guest InfernoX90 Posted June 7, 2015 Share Posted June 7, 2015 I think i read somewhere in the forums that a 89 reatta should run about 14v+, i recently had to change a alternator cause it was reading in the 11v range, and now it reads 13-13.5v with not load going down a road with no load, but as soon as a load is put on it, it drops to the 12v range, and when it comes to a stop it will go as low as 11.9v with a load and 12v without a load at idle. Is it safe to assume this reman alternator is no good? The battery is only a few months old also. Link to comment Share on other sites More sharing options...
