Hello

I have been checking a few things, with a multimeter
and as it stands I think the problem could well be
the wiring between the alternator and the regulator.

with a new battery wired up I was getting readings of 13-14.5v at idle
however as soon as I opened the throttle to 3000rpm
the readings moved to 15-16v (and I think I am right in saying at 3000rpm the norm
is 14-14.5V)

so what I would like to know is what is the maximum voltage output of the alternator
the Haynes states 13.5-15.5V, so I guess that in mind my 16V is about right for the alternator.

The increase in V suggest to me that the alternator is powering the bike Not
the regulator, if that makes sense?

(open throttle Speedo, lights etc go haywire) overcharging

I understand as I have done many a time that putting the multimeter
on the battery, to some extent gives unclear readings, as if the alternator
is not charging the battery properly, the battery will run say 50miles before it dies.

so the plan is to check/cut back the alternator wires again, run a fresh set via
the meter/battery and work from there.

I need to know where the power is going, and what’s causing it as it stands the
Rectifier is not in the link, (and after a call to electrex to ask how to check, was told
"our parts never fail its a wiring problem you have") wait and see I know of one DSC member who returned one because faulty.

maybe I am getting some where?

I hope so just repaired the TV remote after a hot chocolate spill ( and telewest want £12.50 for a replacement) the cheek . . .
