Little Hampden 3. 11,000 Volt Big Dipper Multi-Cache

This is a new series of caches to fill a gap in a quiet area of the Chilterns. It provides walks of varying lengths, so can be done in bits, or all in one go. The cache numbers are just for reference, and don't have to be followed in any particular order. Enjoy the series! :)

At the published coordinates is a sign. The one you require is on the rear of the 11,000 Volts electricity pole (as viewed form the path). The area has become overgrown now the summer is here, access to the pole is from a few Metres uphill from the pole.

Where A =1, and Z = 26 but dropping the leading digit (eg J=10 becomes 0 and  W = 23 becomes 3)

The cache is at  N51 43. (fourth letter) (fifth letter) (fourth letter)   W000 46. (second letter) (seventeenth letter + 3) (eleventh letter)

BYOP.
