I'd say anything more than a few tenths of an ohm would be bad, and most ohmmeters are not reliable down that low. It should read less than 1 ohm for sure D² & 6530 One other item nobody has mentioned yet is if you still have problems with the battery being under charged after the alternator is replaced, it could be a bad battery ground. When mine was bad, I had the same problems. You can quickly test this by checking the resistance between the negative battery cable and the frame. Anything more then a few ohms means the connection is dirty.
