There will be two fuses, one for switched power and one for the memory circuit. The memory fuse will be tied in with some other circuit that is always on such as interior lights, horn, or possibly the cigarette lighter. Also be sure you're using the right ground wire. If you found it by using an ohm meter, you might have found the dash light or tail light wire because they will read very low resistance to ground. Most radios will work when one of those light wires is used as a ground until the lights are turned on. If the radio is also getting a ground through the antenna lead, which is always a very poor ground, the lights fuse will blow when they are turned on.
