Answers :

1. Have an alternator test performed, since your speedo and everything else is electrical a faulty alternator can be the problem.
2. Check your grounds, a bad, broken, corroded, or loose ground can also cause those issues.
Yes if the alternator is out and the battery gets low all kinds of electrical problems will come up. once the problem (battery or alt.) is fixed, the other things should take care of themselves
