Prado 90 Electrical issue

Hello to all from Kenya,

I have a 98 prado and the following issues:

When driving and I step on the brake or turn on indicators, the rev counter drops to zero and just as quickly gets back to normal. When the indicator is on the rev counter jumps as the turn signals blink. This "cutout" is also seen when the radio is on, the whole display switches off. Also when I switch on lights in the evening the use of horn or any electrical equipment will dim the dashboard lights.

sounds like a ground fault, check the negative cable from the battery to body & battery to engine. If that fails look for a loose ground(-) cable somewere behind the dash.

had a very similar problem in an old car of mine, every time i flicked on the high beam the car would stall and clutch start itself again, found the neg cable from the battery to the body had came off and all neg current was going through the motor. reatached and it was as good as new.

Hope that helps
