Always a single click. Sometimes the engine would rotate a fraction of a turn, very, very slowly and then just sit there. Again, all the lights stayed on bright when this no-start condition surfaced too, so the battery was strong. Replacement starter and taking care of all the contact points for the battery cables, and the old battery turned the engine over with no effort at all. So was it the starter twice (it was the first, because it tested bad, but the 2nd one tested good), or the battery cable connections, or some weird combination of the two? Don't know, but it seems to be working now, so I'm happy.
