Petrol Engine Hour Meter
Those of you who have a petrol engined generator, snowmobile, outboard etc might find this interesting.
I have an AC generator. It's maintenance schedule is in hours - for example every 20 hours change the oil. How the hell do you remember or know when the 20 hours is up? I didn't have a clue until I came across this Ebay listing from China.
Anyway I sent off for it and it arrived a few days ago. Easy to fit - just a few turns of wire round the spark plug lead, then clip the wire into a slot in the device - no physical connection or soldering required. At the moment I have the wire just coming out from the spark plug cover but it would be easy to drill a more convenient 3mm hole for the wire
The hourglass image to the left flashes when the device is picking up a signal.
Blow me it worked perfectly I ran the generator for 12 minutes and got 0.2 hours! Very happy with that, at about $7 (£3.50) you can't go wrong.
