RunleaderDigital LCD Maintenance Hour Meter for Small Engine,Waterproof Design,Applicable to Gas Engine Powered Lawn Mower Generator Compressor Motorcycle ATV Outboard Motor Chainsaw etc.

Great little gadget that actually works! Super easy install! No need to drill a hole in generator either. Simply run the wire under the spark plug door and use some double sided tape to mount it. Perfect!!

Took me less than 5 minutes to install. Flush mounted on the upper panel of my generator (see pic).Now I don't have to guess between oil changes. Installation was a breeze, comes with long enough wire, zip ties, fastening hardware.Very simple installation only requires to put the signal wire in the slot on the back of the hour meter, then run it to your spark plug wire and then wrap it around it several times (see pic) and secure with the vendor furnished zip ties. Tested on gen set and work!!Very good product. If anything changes in quality I will edit my review, but as of now it's five stars.

Hello All,My Dad's (rest his soul) vintage (early 1980's Sears Craftsman model) edger rebuild project came out better than expected, especially with the hour meter monitoring (as you can see). I love doing these projects and seeing each of them transform right in front of my eyes. It was fun...Well, it started the first pull and it's a great little hour meter, as well. It all works just Awesome! However, the instructions need a bit of tweaking in my opinion because it is kind of vague on what to do with the sensor pickup wire at the spark plug lead. By the way, I did a "5" wire-loop wrap and zip-tied it off there and it worked great. I even found some original Craftsman stickers too...I test-ran my newly rebuilt edger with its new (waterproof) hour meter for the first time a couple of days ago and it did just fine. It registered just under half an hour (0.4 as you can see in the picture). Now, I will know exactly when to change my break-in oil at 5 hours of use, then 20 hours or whenever I feel the usage is there, rather than guessing.All in all, it's an impressive Edger Project, and that little "red" hour meter is second to none because it's being monitored by yours truly, me. I tried to give you all a before and after view of my little project, so I hope you liked it and its hour meter installation too...Sincerely,Jimbo

First, you can’t beat the price of this thing. Second, it helps track the hours of my mower’s engine run time so that I can change my oil at the right intervals. Finally, it’s really easy to install…It comes with a fairly long wire. I wrapped one end around the spark plug wire, checked the length to where I wanted to mount the display, and tucked the wire into the slot on the back of the display. I mounted the display and secured it with the two included screws. Secured the end of the wire wrap around the spark plug wire with one included zip tie and secured the other end with the other included zip tie. I then trimmed off the the zip tie ends and the excess wire. Easy! Works great!

I put this on a small portable generator. No problem with straight forward installation. Did not rate accuracy because I have not checked that yet

I put these on my 4 stroke outboards, snow blowers, generators and a few other items. Super handy and much easier to track maintenance. Some machines make it hard to access the spark plug wires but I have succeeded using patience. I bought this one to replace one on my old Honda 40 outboard after the battery in the first one finally died - it lived much longer than expected. And they sit out in the Alaska cold and wet year round and keep working - pretty good torture test I think.

So far so good.

recently purchased our 3rd genset. Needed a little meter to track hours for maintenance. This thing did the trick. Installed in less than a minute. Accurate. Great buy.
