1977 RANCHERO with 400 long block, i tried to start the car and the starter stuck for about 10 seconds, now the car has no power at all to anything, was a new starter solenoid and battery, no smoke or electric fire smell,

ANY SUGGESTIONS, PLEASE HELP,:banghead:

Sounds like you have a low voltage situation and the starter engaged and is now stuck.
Remove the (+) battery and see if you can turn the engine over by hand with a suitable ratchet and socket on the crankshaft.
Clean the cables, re-charge the battery and make sure you don't have power going through the solenoid unless it is in the start (w/key) posistion.

Most old Fords have a 'fusable link' built into the positive battery cable. Yours may have burned out.

This link is like one giant fuse and will burn out if the electrical draw is too high. It is specifically designed to prevent fire etc in the event of shorts in the starter motor or solenoid.

Often you can find the link in the positive cable. It looks like a rubber-encased 'bulge' Sometimes it is labelled 'FUSABLE LINK'. You can replace the link (a good idea), bypass it or just get a new positive battery cable.

You can use jumper cables to temporarily bypass the cable in order to test it.

If you have pulled the starter you should notice a burned fuse able link. You can get a used one at a junk yard color coded. If you make one use two wire sizes smaller wire than the large wire. Example if 14 gauge use 18 gauge wire.
Make sure you roll by hand as suggested.
