Diver Dan Posted September 30, 2004 Share Posted September 30, 2004 Randomly, when I step on the brake, all electrical systems will fail. Randomly, some or all electrical systems will recover when I get off the brake pedal. This can happen as often as 80% of the time when I hit the brake. It can happen for six solid weeks and then not happen for 10 months. The local Lexus dealer has been happy to take my money and randomly replace parts, but I still have the problem. Any ideas out there? Quote Link to comment Share on other sites More sharing options...
LLS Posted September 30, 2004 Share Posted September 30, 2004 Bad ground. Reground the engine block and chassis ground and inspect the ground wire itself, not just the connections. Quote Link to comment Share on other sites More sharing options...
sc_toy Posted September 30, 2004 Share Posted September 30, 2004 ^^^ that was my first instinct too... I'd check your main battery to chassis grounds also. Even if it doesn't appear too bad, over time and heat cycling the wires could be getting bad inside. Might be worth running new grounds...
