Did these tests Zirk Bat+to engine block= bat volts
Bat-to alt output terminal= bat volts
Also the Green Flag breakdown guy did some checks came up with
It's the alternator and then ordered the flatbed low loader to get us home
Just ordered an exchange factory recon alternator with 1yr G/tee
Get it hopefully @ 10am tommorrow
Thought I'd best work on a new unit as opposed to a 2nd hand one TB
Thanks Albs for your kind offer

And also MF

As I have a contract with Green Flag in the event of breakdown
To return if req both caravan & car back home from anywhere in UK
Just won't look good if a 2nd hand alternator failed
Down in Cornwall or up in Scotland
Bet they'd take a dim view of accepting all costs a 2nd time
So in this event a receipt for a new one should prevent argument
What a pain it's been to get off
Mainly caused by accessability
Pain is the operatve word Arthur's been active in the knuckles

Roll on 10am tomorrow
