    1987 Rectifier /Regulator

    Part Number 2JA-81960-A0 regulator/rectifier . It's perfectly fit for the 1987 TW200. Does it fit for 1998 TW200? . 1987 TW & 1998 TW 200 electrical Parts are same . Are there Any Difference?

    The only major difference between an ’87 and a ’98 is most of the electrical system

    Feeling lucky ?

    Nope - stator is different (the '87 has a different left hand crankcase cover because of this)

    The main problem is the wiring to the headlight which runs on AC - which is likely to take its power through the regulator, but not through the rectifier. I have no direct experience of the '87, but this would be the logical way to do it, or you'll risk blowing headlight bulbs

    On the '98 it's all DC, so no problem there - straight through both the regulator and rectifier unit

    But there has to be something slightly different with the '87 .......

    If you look at these two pics (right click, “open in new tab”) — there seems to be subtle differences between the two years, including the part number


    87 stator.JPG 87 - vs - 98 98 stator.JPG



    You will also notice the difference between the two parts — and not only visualy, but by the fact that the ’98 has six wires coming out of it — while the ’87 has four

    And (although I can’t find the part schematic to confirm this), it is my belief that in order to fit the ’87 stator, you need the ’87 side casing — and to fit the ’98, you need the ’98 casing

    In addition to this, the ’87 CDI is well known to be very different from the ‘98

    87 - RECTIFIER REG. ASSEMBLY (1KH- 2JA-81960-A0-00


    98 - RECTIFIER REGULATOR ASSEMBLY - 47X-81960-A3-00

    So if you look at my post #4, and the parts numbers above – probably not

    Vishwa – I don’t mean to sound rude, but I seriously think that the only way you’re going to find out is to try it and see. Anything I can come up with parts numbers you can challenge by saying “regional differences”, but at the end of the day, I don’t think anyone’s tried that combination before

    Will it work – I have no idea – I only have “suspicions” that it won’t. Having said that, it’s an easily reversible thing if it doesn’t, and I don’t think that anything is going to come to harm by trying it (apart from your wallet)

    I’ll stay out of this thread for a while – let’s see what other people have to say ……
