Complete electrical power failure

[Martin W]

Hi All, currently waiting for recovery - all electrics suddenly died so assuming 100 fuse. The battery is in the boot as is a spare fuse and I can’t get in - is there a trick someone could dm please? Ta very much!

[Martin W]

Thank you very much to the person who responded - it was greatly appreciated and definitely helped!

what was the solution?

The 100A fuse on the chassis is only to provide a circuit to charge the battery, with possibly the warning lamp too, but mine stayed off even the 100A fuse was cracked.

The fuse down by the battery that isolates the whole car (other than the starter supply) is usually 80A, it is on my Griff anyway.

No solution as of yet sadly - car was recovered home and I’ll have another look this weekend. Not found the 80a fuse yet but the battery was moved to the boot some years ago so perhaps that moved too. It’s due to go in for service and mot in 2 or 3 weeks and I’d prefer it got there under its own steam rather than pay for a low loader, so will try to follow cables from the battery / look at earths and see what I can find. Thanks!

Start at the battery and work forward, connections first etc, assume battery main cable now goes to starter and then a cable to fusebox area?
Identify ground connection too and make sure it's clean metal underneath if bolted to chassis.
Should be fairly basic stuff.

I would hope the fuse is near the fuse box. When my odessey race battery was moved behind the passenger seat, the fuse was left in the footwell protecting the fuse box.

Mine too - it will be down in the passenger footwell on one of the cables, not in the fuse box.

I am not assuming anything. I had similar happen when at the front of the queue at a dual carriageway roundabout.
Most embarrassing. Called my TVR man, who suggested that the.....
The car had simply gone and immobilised itself.
Locking the car and unlocking it again started mine.

Please describe what happened when yours suddenly rolled over and played dead
