haven't progressed any further than I can get the neon working with a battery, there's 14vdc to the connector, when testing the neon in diagnostics I sometimes see various random lights quickly flick on then off, but have not been able to make the neon pulse on.

Did lots of visuals and replaced dead bulbs but I think I'll have to give up for the moment again as its done my head in way too much this time. thanks for all your help.

At least I know I don't have to replace the neon or transformer. thanks again
