When I look at those parts I carefully weigh my options. I usually go with the one with the best warranty for the least amount of money. Some of the remans I have bought, have outlasted new ones. See what one would run through www.rockauto.com. Usually sticking with the MOCO you will get the best luck but also the higher price. You may also have to replace the battery again? Just depends if the alt did any erractic charging. Lars

Hey lars thanks for the input, the moco is $240 so i think i'm gonna talk to the guys at advance auto parts and see what they think. I think my battery is ok though as its putting out steady voltage. I'm going in to get it fixed today before it drains the battery

AND, if you have a battery charger, it would be best to recharge your battery using one of those. Alternators don't really like to be forced to recharge a "low" battery, and I'd say yours qualifies on that score.
I've heard about (and experienced) alternator damage due to uncharged batteries in the past. - Jack |

First did you clear any codes in the diagnostics menu? If no codes were cleared start with clearing them.
You may just have to unplug it with key off. Then with key on engine off plug it back in. Lars

As I recall, this has something to do with a low (or maybe disconnected) battery.
When you reconnected the battery, did you turn the ignition ON before plugging the Gryphon into the OBD port? If not, it did not initialize properly. Do it now. Unplug the Gryphon, turn the ignition ON and plug it back in. Regardless though, if the Gryphon seems to be working fine otherwise, I think the "hit enter" warning will go away after about three startups. (And I just realized that Lars already said to try the "disconnect" procedure - Oh well, it doesn't hurt to repeat it). - Jack |
