Hi John,
Who is ECP? I have asked the club shop for a price on a battery and have found a few options online, will wait and see what the shop comes back with first.
I measured the voltage across the battery, 2.5v
Guess it must have suffered multiple cell failure. Getting access to the battery is going to be fun, I would be lying if I said I knew where it is even located !!
Car is due a service shortly so I guess I can replace the battery and have the coded then.
