orangemach5 Posted January 28, 2009 Share Posted January 28, 2009 Hi all, Engine is all in and running well finally!!! I put a new alternator on, having wired it all up it charges fine but at higher revs it overcharges (16-18V!!). I would of thought it would be a reg problem but the alternator is brand spanky. Its the 80amp version with the 3 pin plug on the rear. Any ideas before i go on a rave to the supplier !! Many thanks Paul Quote Link to comment Share on other sites More sharing options...
steve_d Posted January 29, 2009 Share Posted January 29, 2009 If that 16-18 is measured across an otherwise good condition battery then yes you have a duff one. Steve Quote Link to comment Share on other sites More sharing options...

It registers 17.5 volts on both Optimas ! I spoke to the supplier and he said they cant high speed test them because of the oil fed vac pump on the rear, he is kindly sending me out another . So Ill fit that and see what we get. The last thing i need is 2 fried Optimas! Cheers Quote Link to comment Share on other sites More sharing options...
