Conversation Between Greg Wright and ravenQ8

Dear Sir,

We acquire a Vallach r7 800 radial engine and it comes with Emcotec APS powerfuel pump, I follow the instruction on how to install from piping to electronic connection but it failed. I did the mixing with throttle and with up to 60% travel on separate switch and the pump has a separate power switch and battery but i only get a blinking of the blue light. I used 18 mz futaba. Did i miss something, could you please help on programming or installing this pump.

I am looking forward for your prompt reply and thank you very much


Best regards,


jerry b
