Electric Toothbrush: Guesstimate resistance

[NivagSwerdna]

OK... another repair fail... I have tried to replace the battery in my electric toothbrush and that part went well but it won't charge when on the base.

The unit charges via a coil of wire in the base which sits on a base station... I'm wondering if I broke something along the way..

... my question... What would you expect the resistance of the wound copper wire to be?  I measure 1.7 Ohms does that sound legit or could I have shorted the windings somehow?  It's just copper wire right?

PS
I wish I had measured it at the beginning

Looking at the spool 1.7 ohms sounds fine...
Don't you have a LC meter to throw on it?
What model is it? I have a Philips reject somewhere I may be able to check on.

I actually discovered the problem.... the coil was fine but in the process of removing the PCB to replace the battery a small component had fallen off the board near the plastic retaining lug that hold the board in... I suspected something was up by looking at the appearance of the tiny pads... Anyway I made a huge guess and decided it was a diode that is missing somewhere around my house and had a go at replacing it with a SOD-323 Shottky I had in parts, slightly too big... but it fits and now it charges!
It works! 
Moral of that story.... be very careful hinging out the PCB!

Makes sense, there's gonna have to be a diode to rectify the output of the charging coil.

I had a toothbrush like that years ago. I was unsuccessful in getting it apart non-destructively so I replaced it with the much cheaper $20 Sonicare that uses ordinary AA cells that I charge externally. I swap the cells with a charged pair once a month and it's always good to go.
