i *might* have double posted this - apologies if so...
hi all,
please could anyone who is bored enough have a look at these 2 wiring
diagrams for me...
they are both for the same motorbike, but one is an old one and the other
one is a later (factory modified) one...
the older one is prone to blowing headlight and tail-light bulbs (even LED
ones) but the newer one is much better...

the main difference seems to be that in the later one the 4-wire regulator
has been replaced with a 5-wire one and a bleed resistor added which is used
only when the lights are off...presumably to help protect the regulator by
ensuring there is always a load on it...
i'm not 100% certain that this is the only reason the bulbs are blowing on
the older bikes (e.g. the older ones might have crapper batteries for
example)... but if this is the reason... why would the 5-wire regulator be
the better system ?
if you look at the extra (black) wire on the 5-wire regulator it simply
joins directly with the red wire anyway if you follow the circuit (so long
as the ignition is on).. so what is the point of the extra wire... is the
different regulator probably not the solution ?
both regulators charge the battery at peak ~14.8volts on a long run using
the system for measuring peak voltage which someone previously suggested on
this group -
many thanks !
