    So I just did the tachometer fix where you resolder two of the circuit boards, and it fixed the tachometer (it used to be 500-100 rpm off). Now I’m having an issue with the backlighting on the gauges and I’m wondering what I messed up. It seems that half of the backlights still work, and half don’t, kind of randomly. Does anyone know if this can be caused by me screwing up a solder joint, or could I have messed something else up that caused this?
