the scooter is all back together as it was with just the wassell unit fitted, so probably a good idea to ride it about, that is the best test after all.
thanks for all your contributions

At what rev range were these voltage readings taken?

from tickover, revving it up a bit a few times until no increase in the readings. so not totally controlled, but i was doing this in my badly ventilated workshop with a bike that is running rich and ideally needs setting up, again by riding it...
I think i will see if the owner does want to blat it around a bit, at least til we get the rewound stator back...

I would try and measure the voltage at a constant 3000rpm approx, if the volts are alright at this range I don't think you have a problem.

ok thanks again, so would be looking at around 14v at this rpm ?

Jarv, I agree with Soulsurfer, I don't think the size of the battery is the problem (if indeed there is a problem) my battery is a 7.2 Ah one. btw.

I have a bigger problem at the moment, we've jusrt drive 225 miles up to Wigan to do xmas with the inlaws and we've leftthere frikin present behind :oops: :oops:

Have a good one all ;)

:oops: oh dear. have a good one Colin

just tried it, about 3000 rpm, but only by ear, had a drink lunchtime so can't be arsed with hooking a tacho up....

measured at battery :
14.5v with lights off
around 12.5 with lights on
just over 12 with one pathfinder
11.5 with two

so does that seem ok ?

i did meet the owner for a beer earlier, he is going to ride it about a bit next week, so hopefully it will all be good....

don't you just love lambrettas :mrgreen:
