Why does my 92 lexus sc400 have a good battery but no power at all when cranked, all dash lights on but flicker when cranked. clicking sound from engine fuse box when cranked.

The clicking noise from the fuse box is the starter relay, that's normal considering the rest of the symptoms as it will stop working under a certain voltage like the rest of the lights and whatnot, then the voltage will rise again since all the accessories and everything turned off and everything will try to power on again, making the voltage drops, and so forth. If the battery is good and the car does this, then you definetly have a grounding problem. Either the connector on the battery is loose, or you have a damaged/corroded grounding strap/wire. Start by checking the connections on the battery to see if they are loose or not, and if they are fine, check the wire from the connection for corrosion or damage, and do the same thing for any other ground wires or straps and you will be sure to find your problem and get it starting like it should. The only other possibility which is VERY VERY VERY rare to see is a broken leed on the battery posts, which will not be visible since it happens inside the battery, but if you changed the battery recently or have tested with another battery, you can rule that out from the start and i'm 100% sure you only have a grounding problem.

1992 prelude si - battery/alternator prob?

if you can charge the battery and drive it for a while then sounds like the altenator has failed and is not re-charging the battery, good way to test is to charge the battery, start the car and turn the light on, if everything is dimm or the motor dies there is little to no charge voltage, and will require altenator work
