Could use a bit of help here.. Part # for my 24V regulator is 27700-57010, and the only replacement is a 27700-57080.. I was looking at a few threads, but by the time I got a new password, couldn't "re-find" them.. 1 guy ran into all kinds of trouble, so before I order something, I'd like to figure it all out a bit.. I know mine came from Japan in the 90's, and it's right hand drive with a 2b diesel.. Electric isn't my thing at all, so when the mechanic said I needed an alternator, I took him at his word.. After 6 months and no replacement, I took it to a guy to see if he could rebuild it, only to find it was fine.. He told me I probably needed a voltage regulator(only brought the starter to him).. Anyways, I saw something in the other threads about "round post" and "square post", and got a little lost.. There's 2 large wires and 2 small coming off mine, and they go to round plastic inline fuses... Is this what that referred to..? This is my first 24V vehicle, and my first diesel, so there's a pretty steep learning curve.. If I have to buy a part and adapt it, I'd like as much info as humanly possible..
