Battery connected wrong way round. on Griff 500.!

[griffert]

During a moment of madness I have connected the battery terminals neg to positive, and blown the electrics.
Any guidance of what is likely to have blown would be appreciated, checked various relays etc and some damage has
occured, I have a spare replacement ECU but suspect the immobiliser is dead.
Car is a 94 griffith 500 serpentine, no PAS - if anyone can e-mail me a wiring diagram it would be really helpful.

I think the ECU is protected although I've never tested that. Alarm, radio and any other electronic modules would all be at risk. I wouldn't expect any wiring damage. In your situation I'd reconnect the right way round, check carefully for burning smells/smoke and then see whether anything worked when I switched the ignition on.

Pull fuses for electronic bits. Reconnect battery then replace fuses one by one while checking each system. thats what i would do anyway
