Hi Peter,
My old starter was very clearly well worn and the commutator had worn down significantly. The brushes had obviously been replaced in the past as the soldering job was very poor. So to remove any doubt about the integrity or longevity of the starter then I was going to go down the path of a refurb, maybe trying to get a replacement armarure. Alas, I could not find anyone in Perth who could do a refurb
A used starter is a bit of a gamble as it may not be any better than mine and over here, with Australian used parts sources, it is very difficult to understand if you have been quoted a price or a phone number.
So, I am hoping that a brand new starter solves the problem.
Also, when things like this come up for sale the tendancy is to just act impulsively, especially as it was such a bargain. I can always move it on later if not required.
Cheers,
Steve
