Pantah 1980 500SL GEN light
Posted: Sat Aug 05, 2017 6:11 am
Hello,
Has anyone any experience of the following, the alternator light goes on and off repeatedly, it can be on for a few minutes then of for a while. In eighty odd miles yesterday resulted in me jumping the bike to get home. I can't see me riding for over an hour on the battery only, however the light being on is obviously indicative of not charging.
The battery is new and gives good voltage and holds a load on test, with fly leads to measure the output of the regulator or diode pack it reads just over 1 volt which would make sense if the light was always on but it's very often off for long periods.
A new regulator is available as NOS but runs around £200 so a better understanding of the issue would help before I spend the money.
The alternator output was good and no break down to earth through either lead which have been replaced resently.
I understand that the voltmeter controls the light and it can be on at low RPM with the alternator loaded up
I may splice in a voltmeter in the regulator output and ride the bike to gain a good understanding of the output but having had the bike for only a few weeks I have little experience of the system on a 1980 Duke?
Thanks, Nick.
