Not starting now.....
 

Well i replaced my engine belts, but while i did that, i accidently. moved the alternator into another mount and it hit the part where the alternators power conects to, and sparks ofcourse jumped, now the next time i go to start it, i get nothing, but the headlights do come on, please help if u have any advise, 87 FC, non-turbo.

you blew your main fuse
get a new one it should be an 80 amp buss fuse

have you checked the fusible links

It should be the main fuse in the like Dom said, it's on the drivers side strut tower

i didn't think our rx7's had fusable links. i've never seen one on mine. never heard of one before on the 7's i know some honda's hav ethen but never seen on e for a mazda. but it definetly sounds like the main fuse. i hooked my battery up backwards once and same thing happened. positive the main fuse is blown.
