Hello, I have a 71 Riviera that had an Astra 777 alarm. it was junk. I took it out but now i cant start my car. Battery has 12.46 volts. When I turn the key the car clicks and all the lights go out. Pulling the ground resets the system but still wont turn over. I cannot locate any relays other than the main box that says Astra 777 and another little box that was connected to it. Just had the car running a few days ago before this. I just swapped out alternator due to bad voltage regulator and battery is new. Any suggestions? Thanks.
