Hi hlw49,
I have also had several that destroyed the entire works so there was really no other choice but to replace it all if the customer was willing to pay.
Usually, when the bill approaches over $500.00, they often start thinking of buying a new machine.
Why? New riders and zero-turns are approaching over $3K for even the cheap ones.
Currently, I have 4 expensive zero-turns and riders that people have simply walked away from due to costly stator/ charging system repairs. I had them sign over ownership over to me to prevent issues later. I am fixing them one at a time for resale.
What really hurts, is that most of these customers had already been sold all kinds of bolt up and tune up parts by local "mechanics" before they came to me for actual diagnostics. Later, I found that some of the parts changers did not even have a multimeter, and if they did, they had no idea how to diagnose anything electrical.
In the recent years, I've also had to tell the customer that parts must be paid before I will complete repairs after needed teardown and testing evaluation and that has reduced my outlay costs for their parts.
It truly tests if they are serious about repairs.
If they refuse repairs, I tell them to bring enough money for my evaluation labor time along with a couple of boxes for parts, because I am not putting it back together for free.
I simply got fed up with "free estimates" and the "I'll pay you on Friday" story once they have already got their machine back.
Not to sound heartless, because yes, it is the responsibility of anyone able to care for widows and orphans as taught by the bible. There is more to the passage, but I will not start preaching. It all comes down to if a person is worthy of aid a relief regardless.
