Stator checking without electrical system in place?

[Guest]

Not sure if that makes sense!?

I am going to repaint the 450's engine and am checking elements and replacing gaskets, etc... The bike's wiring harness was off when I got the bike.

I have taken the stator cover off.



Now my big question ( forgive my ignorance, but I know and understand nothing of electrics...): can it be tested off the bike or does it need to be fitted to the electrical system?

Thank you!

If you follow the wires that pass thru that rubber grommet in top left of your photo, you'll find that they are the three stator output wires. Disconnected from harness, you can measure the ohm resistance between any two combination of wires- should be about 1 ohm (you will need a decent multimeter as lots won't measure this small a resistance). Then check for continuity from each of these wires to the metal frame of stator ( run one meter probe down against the stator core)- you should get NO continuity meaning very high resistance.
Your stator has gotten very hot at some time (BBQ color) which means trouble even if your stator appears to test good. Personally, I'd start looking for replacement just in case.

Thank Tom! I was guessing it looked a bit burned...

I will get a friend to test it for me and then see which direction I need to take.

Hi,

Have a look.

Your stator is burnt.You have what looks like bare copper at the 1 o'clock position.

A chrispy critter for sure, but it should last long enough to get it bolted back up.
