Right bought a flywheel puller i checked the coils for damage and resistance checked the stator loom all good re done all the earth connections as some of the wires where down few strands install a bridge rectifier like this took it for blast round the block and the rectifier
what that big sliver thing ? and the extra resistor in there for ? think my fault must be with the transval 415 voltage regulator just order a new one as suggested but under load getting a steady 5v dc from digital meter to the fan
