My sons old (1970s?)Ace Ambassador has finaly died and so he has just aquired a (much!!!) newer Abbey lancaster 4 birth (1984)which to be fair is in very tidy condition. It has been used on permenant site by its last owner but and has a very basic mains connection. The Ace was fully rewired with a CF9b Zig unit wich works very well but we have lost the fitting/wiring instruction I have contacted Zig to see if we can get the instructions has anyone got a set or any tips.
