Thank you, imhififan. Also, I will appreciate very much if you would tell me how to measure DC resistance. Where in the unit?

correct observation imhififan, Accus have different wiring colors, despite generic schematic is the same. not sure about resistance, using power VARIAC transformer starting with 0V AC and measuring major operational voltages (for example large cap banks) is the most reliable way to make sure no damage if wiring change is wrong. |
1=white+orange 2= red 3= blue 4= black+yellow 5= brown 6=noneTo measure DC resistance, you need to pull out all transformer primary winding wires from the quick connect terminals, make sure all wires not touching each others, using a DMM to measure the following resistance: white - orange = ? ohm white - red = ? ohm white - blue = ? ohm white - black = ? ohm white - yellow = ? ohm white - brown = ? ohm orange - red = ? ohm orange - blue = ? ohm orange - black = ? ohm orange - yellow = ? ohm orange - brown = ? ohm black - red = ? ohm black - blue = ? ohm black - yellow = ? ohm black - brown = ? ohm yellow - red = ? ohm yellow - blue = ? ohm yellow - brown = ? ohm Please report back the result and see if we can figure out which wires belong to the two sets of primary winding.
