Ive recently taken my 1800 apart and cleaned it. When I first tried it, the latch solenoid fired repeatedly like a machine gun. I didnt notice that the latch solenoid resistor had become unattached at one end. I'm not very electrically/mechanically inclined btw. Ive since taken a wire and wrapped it around the end of the resistor and where it connected to. Now once the coin is dropped, the latch solenoid now fires 3 times instead of once and I cannot make a selection. Im not sure if its my connection, or maybe a leaf switch or if something else was damaged when the resistor was disconnected. I shot a short video of it. The same thing happens with the other solenoid in the coin mech. The fuses are ok.

Any ideas are much appreciated. Thanks
