    TMR1002E regulator/rectifier???

    My 1978 GS1000 has a regulator/rectifier with part #TMR1002E on it as shown below. After a quick fleabay search it looks as if this is from a later model GS1000. This bike originally had a separate regulator and rectifier by what I'm seeing on the parts fiche. Evidently it must have fried them at some point in its life.

    Is this any better than a SH775 unit or worse? Or should I got back to separate components?

    Thanks!

    Definitely do NOT go back to original.

    If your current unit is OEM (possibly from another year), it's likely still a shunt R/R.

    My vote is to go with an SH775.

      This thread describes removing the vestiges of a dual R and R setup and replacing with SH-775

        The original rectification/regulation components were pretty bad on these Suzukis. Not so with Hondas. Don't know about Kawis and the rest, but I figure it's the source manufacturer of components Suzuki used then.

        If you combine the very-common poor battery care with weak components, Suzuki failure seems inevitable.
