When doing work you can recover your cost it is often better to pay more

When working a large motor speed control quit. The factory repair main
replaced 2 large diodes. There were 3 of them as this was a 3 phase
system. I asked him to replace the 3 rd one. He said they were $ 50
each. I told him I don't care as it was costing up about $ 1000 an hour
to be down plus your charge to come back in if needed. It may not need
changing, but why take the chance.




exactly. If you have a car with a timing belt, it is often just the
cost of parts to replace the water pump at the same time. There are a
lot of situations like that. $10 or $40 now rather than $500 if it
breaks next week.
