My 2001 Grand Cherokee Laredo will start but run only for a second. If I do manage to keep it running the speedo bounces all over and the over drive turns off. Ive used the key dance to get a code but just get the word DONE. I have been told it could be the alternator but would that make the speedo and overdrive go haywire? I would like to try this myself before taking it to a garage. Any ideas? It has the straight six with 116k on it.

Don't think the key dance works on that year. You really need a scan tool to see what codes are stored.
If you suspect the alternator has diode problems, disconnect the alternator connector and see if your problem goes away.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
