the original power antenna finally broke on my 1995 240sx se. the plastic toothed cord that pushes and pulls on the mast broke.

so i went and bought a generic replace power antenna assembly from autozone. i removed the old antenna assembly and clipped the connector from the car's wiring harness and stirpped the wires and twisted them on wires of the new antenna assembly.

i turned the car on and the radio is now dead and the digital clock in the speedometer is also now non functional. the radio and the clock still light up when i turn on the head lights. but the radio just doesn't turn on. i tried it with the new antenna not wired up, with the wires connected both ways. i checked all the audio fuses both under the hood and the interior box. every thing else electrical works just fine too.

what did i do wrong and how do i fix this ?

Check all the fuses. There is a fuse that is 12v constant that runs clock and stereo memory (some stereos won't work without the memory wire hooked up) the fuse is inside the car on driver side but can't remember what its called.

Yeah i blew the 7.5 electron batt fuse. Going to have to find something to insulate the stripped wire ends until i am ready to wire up the new antenna.

You can also just get a new antannae mast with the plastic toothed piece on it from the dealer for $60. Then you don't have to change out the entire motor.

so i got a generic third party replacement antenna in and working. it has a reception problem where there is slight static and if i stand near the antenna, touch it, or stand in certain places around the car the reception falls off. i'm thinking it has to be a grounding issue.
