3200GT - Electrics issue (lighting and horn.)

[ajb101]

Hi all,

Has anyone hear experienced an issue where the main beam, front fogs, rear brake lights and horn don't work? Yet dipped beam and indicators work fine (can't remember if rear fogs are working or not?)

I've had the fuses checked, it spent several hours at Dick Lovett trying to diagnose the problem, but they were flying blind as they didn't have the schematics to hand. I'm worried it signifies the ECU is knackered (or one or more of them are.)

Thanks in advance,
Alex

Fuse 16 is first one to check. Also check you have a 12 volt positive supply to the actual fuse box. There is a fuse for the LCU # 112 I think,would need to check the Workshop manual.

They had positive feed coming out of the lighting ecu/fuse area (under the passenger foot well.) What I couldn't determine on my own was the output coming from the fuse box on the bulkhead because for some reason the cam covers (?) were so far back if couldn't be lifted off by me!)

I don't remember if they confirmed if there was power at that point or not.
