OK I.ve' now got this working again...

2n3904 wired as

B C
C rather than B
E E
can anyone confirm pinouts for 2N3904 & 2N3906 ?

4K7 resistor across LED stops relay energising... replaced with 10k & seems
ok

LED still glows before relay energises ( Not really a problem though as I
cm mount an LED OFF the relay output )

Thanks
