Forum Member BigAdam just called me - he's off on a 4000km odyssey into the Outback and is in the Flinders Ranges, about 430km from Adelaide.
Which is to say that he's a long way out of town - where he is now, the Buggrall grows a metre high and you can see Thursday coming on Tuesday...
And BigAdam has an electrical problem and having quickly exhausted my meagre electrical knowledge, he's asked me to pose a question for the Forum's Brains Trust...
Essentially the bike's not charging enough to fire up without a jump-start (I haven't yet told him of the dangers of that); we've discussed the need for personal hygiene on electrical connections and earths, but we're suspecting that his almost-new Rec-reg is misbehaving.
It was replaced by the PO shortly before he bought the bike, but probably just with another problematic OEM item instead of an upgraded one; before he left, BigAdam checked the brown connectors and they were fine (this seems to be true of very early, Australia-delivered bikes - both of the Capos in this household have neatly soldered wires in the brown connectors), but he's only getting about 12.4 volts to the battery at idle.
He says the Rec-reg unit is getting as hot as it normally does and when we spoke on the phone a moment ago, I suggested that he checks he's getting exactly the same current on each of the three yellow wires on each side of the brown connectors, to eliminate those from the equation.
However, he's leaning towards a dying Rec-reg and there's a local car mechanic who has access to "some" motorcycle parts at about 24 hours notice (regular post only gets delivered to this area once or twice a week).
So BigAdam's specific question is: can any modern Rec-reg work, assuming it can be made to fit, or are there different "types" that will and will not work on our bikes?
The mechanic reckons the battery is dead and they're going to get a new one, but I think he'd like to know about the suitability of what can be found, probably in a wreckers yard where there won't be a lot of choice.
Hoping someone can cast some light...
