No Electrics

paulmchristie · February 22, 2010

Hi Guy's I'm new to this and too my Lexus LS400 1992 'J' reg. When I first seen the car it ran perfect except it needed to be jumped as Battery on the car was too small??. Since then the car has failed to start and when it did there was no lights, no radio, no dash illumination the list goes on. I replaced the Battery with a heavy duty Battery from Izuzu and now the car starts. However there is still no electrics except the horn and the hazards light switch though no hazards!!!! Can any one help as to where to start. I have mechanics as friends but as you know when you need help they always seem so busy!!!!!!

Hello and welcome to the LOC.

1st thing is did you connect the Battery the wrong way around as the Lexus batteries have the +ve and -ve terminals the opposite way to most batteries so easily done.

In the engine compartment fusebox (passenger side infront of the coolant reservoir) remove the lid ( 2 plastic bolts) and check carefully the 120A fuseable link which is the main cause of your symptoms after Battery problems.

If this has blown only replace with the correct type and rating.

If the fuse is OK please let us know as we will try and offer further advice
