I bought an additional new TIU. It has the latest firmware 6.10. The fixed channel 1 works fine. However, fixed channel 2 puts out no DCS Signal. Any engine starts up automatically and I have no control with DCS remote in shutting it down engine, etc. The same happens when putting the variable channels 1 & 2 in fixed mode. I have reset the TIU to factory defaults. I tried reloading the TIU's firmware but same thing happens with no DCS Singnal on fixed channel 2, variable channels 1 & 2 in fixed mode. Is there anything else I can try doing before sending the TIU to MTH for repair?
Thanks
