I plug my charger into power and immediately, the reversed, charging, and charged/maintaining leds start flashing. Nothing else will turn on and No other trouble codes. I opened up the case to see if i could spot anything. The only thing i noticed is if looking at the xformer from the front of the unit. There are three wired coming off the top of it but looks like there should be a 4th. From left to right the wires go Brown-yellow-"missing wire"-brown. The only reason i say that there is a missing wire is the connecter is there but it looks as though the wire has been pulled out of it. So if there is infact a wire missing there. Where would the other end go and would it cause my issue of the three leds blinking and the unit being inoperable? Thank you in advance.
