thanks viking for the response. I'm not sure how I can tell whether the wires are misconnected, but the washer now seems to agitate, which I don't know if it's the same as spinning. So hopefully, that means that it works. Ideally, I would like to know what a solenoid is and how that differs from a cam etc etc. But I'm not that well-versed in parts nor can I find labeled diagrams that would help remedy this. Also left and right is hard to contextualize for me, since there are some diagrams that have the entire gearcase pulled out and snapped from top-down than bottom-up, as I've been accustomed to viewing it.
With regard to the the gear case oil, what would be a way to measure a clear deficit of it? I've only had it tilted front face down when needed upon noticing it leaking. But it's been down for about 6 hours total, I believe, which is how much time I've spent so far puzzling over it. Thanks.
