Im not that good with electrics but am assuming it is the regulater or altenator, I know regulaters are a problem but thought that it was on the early ss's mine is a 97, So how do I check the regulator and altenator or could there be anything else causing the light to stay on |
Could be the regulator, especially as it was OK for the first mile, but first give the battery a good charge.
With the battery back on the bike make sure that the battery voltage rises slightly when you rev the engine (you should see your headlight get a little brighter).
If the battery voltage does not rise when you rev the engine it's possible the charging system (either regulator or alternator) is shot.
Before delving too deeply into these two, it's worth checking for bad conenctions. If the bike was OK when you put it away 5 months ago corrosion may have set in in the connectors or earths.
There are a number of earlier posts that go into detail about testing regulators and alternators.....
