Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

DOOR REVERSAL
The appliance is normally supplied with doors which open from left to right. To change the opening direction, proceed as follows: Bottom door: 1. Unclip and remove the ventilation grille (A). 2. Unscrew and remove the lower hinge (B) and slide the lower door from its top hinge. 3. Unscrew the pin (C) from the hinge and re�t it onto the hinge on the opposite side. 4. Re�t the lower door onto pin (C) and reassemble the lower hinge (B) on the opposite side. 5. Break off the plug (D) from the ventilation grille. You may need a pair of pliers for this. 6. Fit the plug (E) (supplied with the appliance) into the slot left open on the other side. 7. Re�t the ventilation grille (A) clipping it into position. Fig. 3 Top door: 1. Unscrew the hinge (G) and remove the upper door. 2. Unscrew the pin (I) from hinge (G) and re�t the pin into the same hole, but on the opposite side of the hinge. 3. Unscrew the pin (L) from the upper hinge and re�t it in the hinge on the opposite side. 4. Fit the upper door onto the pin (L); re�t hinge (G) on the opposite side. Adjusting the alignment of the upper door If, after having changed the opening direction, the door is not properly aligned, the upper hinge can be adjusted. To do this, slacken the pin (L) (using a 12 mm spanner) and the self-tapping screw located under the hinge (using a Phillips screwdriver); align the door, then retighten the screw and the pin.
