1993 Lexus LS 400

Electrical problem
1993 Lexus LS 400 V8 Two Wheel Drive Automatic 190, 00 miles

HELLO. PUT IN A NEW BATTERY. RADIO PLAYS.
TURN KEY EVERYTHING GOES DEAD. CHECKED ALL FUSES THEY ARE GOOD. Could it be a loose cable on the starter motor?

Check voltage circuits at the starter relay. Terminal 1 goes hot with the key in the crank position. Terminal 2 is hot all the time. Ground for the coil side of starter relay has to do with security system, I can't rule that out. Any testing at the relay, make sure tranny is in park or neutral and the e-brake is set.
