Electrical fuses are something I am very familiar with, especially in larger electrical/electronic devices. The genset on our house failed to start -after- it had been jump-started from a car battery and ran for a while. I figured a fuse blew or something else stupid broke. We bought a new battery for it yesterday, and I have spent 3 hours, used 4 different types of "tamper resistent" screw bits (over 30 screws total), 3 different sized sockets... and vice grips, to get the control box out, and find the 3/4 amp fuse in the control box "open". I'm not sure that is all that is wrong, yet. But I am fuming over the poor design choices. I'll be modifying the design when I reassemble it with an externally accessible fuse holder.

Luckily, it's a nice day to be tinkering.

But please, as "you" design things that have protection devices (fuses, etc), please remember to make them accessible.

Update: It was just the fuse. But now there is an easy to replace fuse in an accessible fuseholder.

It sounds like a job security measure to me...

"My genset isn't working. Can you send someone out?"

"That sure took a lot of fancy tools to fix it. What was wrong?"

"The control module protection linkage."

"Ooooh.... Sounds complicated. Thank you. Here's your check for $1200."

Agreed, that is exactly what it is. An RCO: Revenue Creation Opportunity.

Too much of our current choices in life have RCO's engineered into the business model of the provider. And yes, I'm guilty of the same.

Next time I have to deal with a fuse or breaker, I am definitely going to refer to it as a "control module protection linkage."
