Thanks for all the replys
we've made progress. We been staying at the municiple campsite ( awful btw) and a guy turned up this morning who claimed to be a alternator specialist so we stripped off the old one and he took it off for repair.
Whilst we were waiting we visited the scrap yard looking for an alternative. After much typical Moroccan it'll be here at 2 pm then just a minute we finally got our hands on one
I think we ended up paying 'desperate tourist In a festival' price and could get one cheaper at home, but we were pretty desparate
In the meantime alternator specialist returned without fixing the old one. Got the scrap one fitted and everything seems to be working perfectly now. Hopefully we'll get back off road tomorrow with a slightly modified route
We only found out about the scrap yard through reading this forum so once again has turned out to be a fantastic source of information.
The whole issue has been a bit of a wake up call. If it had happened a day or 2 earlier we would have been deep in the WS luckily we were only 30k from Tarmac when it happened. Last year we were a solo vehicle and would have been completely stuck. This year we had two. Thinking about carrying a spare alternator now and a jump start pack.
