Electrical problem

[Jon Melhuish]

last night I was working on my car and I turned the stereo on and it came on with no sound....I thought maybe the stereo was fried so I swapped it for another.....same thing lights are on no sound . I then tested the old stereo directly on the battery with one of the speakers it worked fine . Thinking its an electrical problem I tried to roll the starter over.....no luck , the relay is clicking and I have power at the starter . It is a brand new starter ...so I try it right off the battery it works . Now I try other stuff....line loc solenoid no longer engages unless the key is in the starting position.....I turn the fan on and the power to the stereo goes off . ONE A.M GO TO BED

I obviously have done something wrong any hints on where to start.

check the chassis ground wires under the hood and the one that goes to the moter.

Did you check the cables on the battery too? I've had a car not start before and all I needed to do was just take off and clean the negative cable and re-install it.

Where I would start also. Then use a multitester at the fusebox to determine if 12 volts are getting thru the bulkhead connecter.
