Multi Electrical Faults! Mk 1

[Gasman]

Hi - Mk 1 2.3l Auto Ghia X.

 

Been sat on the drive not being used for a while. The battery was flat and somehow (don't ask!), when we went to jump start it, the red & black leads were briefly crossed!

 

Anyway, started first turn and all seemed fine, except that the following weren't working:

 

Radio

Central Locking

Indicators

Interior Lights

Boot lock

 

I checked the main fuses and the 10 amp radio fuse had blown. Replaced and radio works fine again.

 

But does anyone have any ideas what might be causing the other problems? Could it be another fuse? Are they related in anyway? Is it just coincidence?

 

Especially, why would the boot not open? Even with the key in the lock, or using the internal locking / unlocking, it doesn't seem to want to unlock and open. Any thoughts / advice / pointers much appreciated!

 

PS - The front windows don't work either - but, haven't for a while. Almost certainly a door gaiter wiring issue - but do they need to work for an MOT? Thanks.
