G'day.
Well I was just going to log off & do some work & I saw your question & had to answer.
I HATE IT when people take advantage of female bike owners/customers.
It sounds like you could use all (or ANY) help you can get.
So I want to answer your questions as accuratly as I can get.
Should you now pay for another regulator-I should think not.-the shop should sort this out for you-If they fitted a regulator WITHOUT testing the stator(which they should have to find out what caused the regulator to go)-& then burn out the good NEW regulator because of the stator-& then now want to charge YOU for the second regulator-NO WAY.
I don't know what else to say!
Heres a link to the part you need & fitting a regulator is usually pritty easy -un-bolt it- dis-connect it- reconect new one & bolt in place.Heres the link with the part & price.It seems that there are two types of regulator.
One is $184.79 & the other $213.31(US)

Let me know if I can help in any other way
Kindest of regards Andrew Porrelli
