I give up now. I'm not going to help now even if you come back.
I'm not going to waste any more of my time with people who ask questions, expecting an answer (I assume) and don't bother to come back.
And what the power supply and battery has to do with changing the code, goodness only knows.
I'd love to know how you 'checked them' though.
Come back with the exact age and size of your battery, Charging Voltage, Ambient Temperature, DC Voltage, & Ampere hour Capacity to prove you've at least done that bit correctly, if you do, my initial offer still stands
ps
I must admit I also take exception to the 'installer scam' comment though.
