12v wiring fuse question

[dig-dug-dan]

I am going to wire in a hidden hour counter in my crushers as i suspect certain hirers of disconnecting the exisiing counter in an attempt to defraud.

I have the hour counters,and i can pick up a live feed off the cooling fan, but wondering if i need an inline fuse? If so, any clue as to what size fuse? The hour counters are 0.8watts consumption

A fuse protects the wiring upstream so it may not need one but a 2A one would suffice.

You'll be hard pressed to find a fuse small enough.

 

24w@12v=2amps iirc.

Thats sorted then, will wire it in and not worry, fan wiring has a fuse !

roll up unannounced for a 'routine maintenance checkup' and see if thats the case. if it is, take them off site immediately, you dont want to be hiring to scum.

Well i kind of what to catch people out, and take the money off their card once i confront them with the evidence!, then not hire to them again, and they would be stuffed as no one else really doing it round here!

Its theft at the end of the day. I only suspect one hirer of doing this, they drew attention to themselves by keep in mentioning the hours, but i saw the pile of stuff they had to crush, and knew it was a two day hire in the back of my mind!

Another option might be a tracker, I think some of them can show whether the engine is running etc

i wouldn't care if they were stuffed or not. They are straight up stealing from you and to your face to boot. 

 

Amend your terms to include 'any unauthorised tampering with any part of the machine will result in a £1000 charge to re certify'. I'd put a couple of counters as well, one that is very hard to get it that you will only need if they pull your other one.

The fan is running all the time the engine is switched on is it? it's not on a thermostat?

The fan comes on approx 40 seconds after the engime has started, and stays running until you switch the engine off. If the fan fails for whatever reason, the crusher jaw will not work.
