1990 Lexus LS 400 V8 Two Wheel Drive Automatic 345250 miles
After my son took a speed bump/drain at excessive speed, damage was done to exhaust, rear shocks, and some electronics. The instriment panel lights work, but tach and speedo don't operate (fuel gauge reads erratically), temp gauge seems o.K.
In addition, radio has power, but no audio. Also, electric tilt feature on steering wheel is no longer operative. I checked all fuses, fusible links, and chassis ground coming from powertrain; all seem o.K.
Can't find a common denominator for the electrical issues; would appreciate any suggestions.
