1 is over-range, high resistance. It's what it should be between the windings and case.

Thanks - so, it's an actual result? Since I couldn't see any change/movement in the display, I assumed it wasn't. When I connected the two probes I got 0.2

Is black probe on the shiny steel in the stator core ok?

Hi suzyj.  Thanks for clearing that up

I would run a magnet through that greasy oil as a test. How does it feel between the fingers? Im thinking metal particles or possible water vapour build up. What is your breather set up?

If the voltage output numbers are insufficient then replace the stator. Looks burned up.

I'll look up starter replacements. I did one in a Multi 18 months ago. I went with what local shops use, Arrowhead iirc.

For aftermarket starters, Arrowhead were half the price of oem down here and is a brand used by local bike shops. I paid about $400-$500 AUD. There are no name starters cheaper by half again but probably not trustworthy.

I'm concerned about that oil sludge.  Water entrapment or metal particles can sludge up the oil to make a paste.

Tomorrow I'll put in a new stator, aftermarket ElectroSport, same shop and brand as last year. I'll arrange the rubber gromet differently. This installation allowed water in, but not out.

The new stator gave the same 0.6 between yellows as the burned one.

OEM Denzo used, but working starter too.

Starter, stator and new rear brake line. Easy enough?  [coffee]

That includes a new rear brake line. My wheel ate through the thing. Fiddly work. Done.

It also includes deciding, half way through, to cry/give up/try again when a couple of side cover bolts couldn't find their threads.  I might have used too little Threebond....  For sure I was clumsy putting the cover back on and touched/removed the grey stuff several times.

OIL LEAK  [bang] [bang]
This was when I stepped back and had to decide if I could believe that someone would show up and do the work for me. Or do it again myself. This second time one of the bolts got hold of threads again, I used more Threebond and put the cover on neatly. I haven't started it again yet, but there is no dripping oil. For now.

Crossing fingers for the starter to hold and for the oil to stay in the engine. I'll have the mechanic use proper Timesert next time (they just used longer bolts)(not good enough). Maybe I'll do it myself....
