I have a 1990 Mazda bravo B2600 , all the headlight and dash cluster worked fine ,I took it to get polished and when it came back there was some polish under the bonnet so I gave it a quick squirt but didn't spray the motor or anything .

When I turned the car back on I lost all lights and my dash cluster .I'm assuming water got in somewhere but I'm not quite sure where to look .

Also my temp gauge doesn't work does anyone know where the sender is so I can test it ?

Cheers in advance

 

Hmm - both the headlights and the cluster lights are both controlled by the headlight switch of the combination switch. When the cluster lights go out, the front marker lights and tail lights go out, on the same circuit. However, you need to troubleshoot that, see if power is getting TO the headlight switch; check fuses under the hood and under the dash.

If the cluster meters are not operating, then check the "meter" fuse.

So that's where to start. Do you have a repair manual?
