How to test a Reg/Rec without a meter

Is it as easy as putting the lights on and seeing if the bulbs get
brighter when revving the engine?

 

It was on Sally's CBR400. Brighter means _significantly_ brighter though. If
only one of the three phases is knackered, the brightness will go up a tiny
amount.

I'm not asking because I think one is knackered

I'm going to have a look at a bike today and the reg/rec has been cited
as one of the things likely to fry.

So if the thing gets brighter (the lights) that's a good thing yes?
Unless they go bulb poppingly bright?

I've never bought a really SOB before so don't know these things. This
one came out when I was just old enough to get my provisional licence.

When mine went, it started misfiring first then after about a day, the
charge was so low that the fucker cut out and wouldn't start.

 

Depends on the bike. On some, all it tells you is that the alternator is
working.

That'll do. With no reliable method of testing I'll have to rely on
blind faith and luck.

Heh. If I'm passing a Maplin's in Morden (pretty much where the bike is)
I reckon a tenner on a crappo meter's going to be a wise investment

 

Use an oscilloscope.

WC using an oscilloscope.

"how do you get live8 on this thing?"

I thinks you've hit on a way for WC to test his Reg Rec there. The pitch of
the scream should be proportional to the voltage. Or is it that the angle of
the dangle is inversely proportional to the heat of the meat?
