HMM, ive got it testing 2 voltages and it works, but if I drop the coltage on the RB test it's fine, re-apply power and it goes back to testing, but if I drop the voltage on the RC test then it does not update the value and stays in the lower voltage mode, although the relay does click on and off.

Any ideas?
