Customer Question

Bought a 2015 Toyota RAV4 at an Auction. It was sold as flooded but runs and drives perfectly. I jumped the battery to start the engine and I drove it home,a distance of about 90 miles. Parked it and thought the distance had charged the battery but NO. Got a booster with 12 and 24 volts. In my ignorance switched the button to 24 volts. The whole electrical system shut down ; a friend was able to start the engine but the steering wheel is stiff, the brakes light are out, the trans lever was forced to shift to drive, dashboard lights out,wipers won't work. All the seen fuses look ok. Where else can l check to resolve the problem
JA: Have you checked the fuses? The dashboard bulbs?
Customer: Yes, except there are some hidden one
JA: Are you fixing your RAV4 yourself? What have you tried so far?
Customer: Yes the dashboard lights are out
JA: Anything else you want the mechanic to know before I connect you?
Customer: A friend knowledgeable in fixing car is helping

Well to start you know the battery is bad. Get a new one and stop with the jumping. Check the alternator output when it is running. Check each fuse with a DMM or at least a test light. Each circuit that doesn't work needs to be treated individually. Checking for power to each component. Going to be a slow tedious process.

Yes 24 volts is bad but the circuits are protected. Good luck.
