This morning the Toyota echo barely turned over. Was running OK the day before.. put the battery charger on it. Starts OK. But had similar problem in 2005. Alternator
Was bad and was replaced. Could the alternator go bad that fast? No warning lights. Had the same problem in 2005. Alternator drained the battery. Purchashed July 2005.
Alternator not very old. Cost $500.00 to have it installed.

Have to know for sure. Will check it out at the mechanic

If you got a rebuilt alternator then yes, it could go that quick.

Many auto parts stores can test alternators for free.

You might also want to get your battery tested as well, because a bad battery, or one that's going bad, will ruin your alternator quick.

I don't necessarily agree here. What kills alternators quicker than anything is loose connections. The worst one to find is a corroded bulkhead wire.

A bad alternator is not going to make the car turn over slow; a bad battery will. However, a bad alternator can drain a good battery if it's not addressed. Is your battery light on?
