Okay - where does one connect the wire that gets wrapped around the plug wire?

  • One End Gets Wrapped Around The Spark Plug Boot And The Other End Snaps IN to The Plastic meter.

    By Jim Reilley on July 11, 2017


I bought this but can figure out what to quite wrap it around on my crf150r. Have tried two diffent spots nad hasnt worked yet. Can anyone help

  • just wrap meter wire end 5 or 6 times around the lower end of spark plug wire. That's it! Works great.

Will this work on a twin cylinder engine

  • Yes it should.

    By Rebecca Woods on February 26, 2018


How long is the cable on this tach?

  • I would say it's over 2 feet long. Can't get to mine for an exact measurement due to a foot of snow blocking my tractor shed!

    By Pete on February 17, 2018


Can the unit be reset to zero after registering an interval of time?

  • I don't believe so. Just continuous run time

    By marple200 on February 1, 2018


Is this a tachometer for rpm's?

  • No. It will just record hours

Is battery replaceable? Does it retain total hours when you replace battery? Is it waterproof? Install with double sided tape?

  • Battery is not replaceable it does not say if it is waterproof i. Used 2 screws that came with it to mount to a bracket

    By Amazon Customer on November 21, 2017


What happens when the battery dies after 2-3 years? Buy a new unit that will be back at zero hours completely defeating the purpose of this meter?

  • In 2-3 years when the battery dies and the unit "may" go back to zero (presuming that this does not have circuit board memory)., then the unit is cheap enough to just replace. Even if you could replace the battery, more than likely it would still zero-out when you replaced it. Most people use hours meter just to mark s… see more In 2-3 years when the battery dies and the unit "may" go back to zero (presuming that this does not have circuit board memory)., then the unit is cheap enough to just replace.

will this work on a motor that has electronic fuel injection?

  • Yes it will it has nothing to do with that fuel injection when the engine is running it senses electricity flowing through the spark plug coil or from the coil to the spark plug all you have to do is wrap it around one of the spark plug wires that's all you have to do wraparound that thing when you cut the motor off it… see more Yes it will it has nothing to do with that fuel injection when the engine is running it senses electricity flowing through the spark plug coil or from the coil to the spark plug all you have to do is wrap it around one of the spark plug wires that's all you have to do wraparound that thing when you cut the motor off it stops registering when you turn the motor back on it starts counting your time again see less

    Bought this for a Predator 212. It screwed right into the airbox without a drill. and I coiled it around the spark plug 7 times so it would register. My wire was roughly 4 feet long. It works as it should. There is a battery on these things and only time will tell how long it lasts. The thing is sealed so either you will have to break it open to swap the battery or buy a new one. But if it were to not be sealed then it wouldnt be waterproof so nobody can really find one thats waterproof and not sealed. But overall I do recommend this product

    Purchased for my Honda eu2000i generator (that does not come with an hour meter). Five wraps around the spark plug wire starting at the boot and easy to fish the wire thru to the meter mounted (via provided screws) to the top of the case near the handle. Cut away the excess wire that was not needed and it starting working when the generator was started. Measures tenths (one 10th = 6 minutes) and whole hours. This is needed to track when to change the oil. Only likely issue will be the non-replaceable battery.......when it runs out, time to buy another one. Unsure how long battery will last.

    It works. Instructions didn't mention where to put the other end of the wire, but it's pretty obvious I guess (in the slot of the meter's case). Meter display remains on at all times, the little hour-glass blinks when the motor is operating (if you wired it correctly and it's not broken). It remains to be seen how long it'll last being on all the time like it is, but as long as I write down the time every couple weeks or so I should be fine even if it dies. For a few bucks, it's not bad. For installing the wire, I zip-tied one end parallel to the plug wire, made a 90-degree bend and wrapped it tight exactly 5 times (ending on the same side of the plug wire that I started on), made another 90-degree bend to get parallel again, then zip-tie tight so the coil doesn't get loose. Would have also put heat-shrink on at this point, but didn't have any big enough to fit over the boot that could also shrink to fit the wire. After installing the coil, I simply routed the wire around the motor shroud, installed the meter on the wire where I wanted it mounted, then stuck it in place with some heavy-duty scotch 3m fasteners.

    Bought this to track the hours on my Crraftsman R1000 lawn tractor. Works great. I used double sided 3M outdoor tape to attach it on a recessed area near the oil cap. Just a few minor things to be aware of; I needed to remove many parts from around the engine to get at the spark plug wire. Not a fault of the meter. Just the nature of the design on this particular mower. When I finally got to the plug wire, I wrapped the sensor wire 5 times around the spark plug wire approximately 3/4" from the boot. I tie wrapped everything securely and routed the sensor wire up to an opening near where I planned on mounting the meter. I ended up with about 6" of extra wire length, so I snipped that off to keep everything neat. The instructions are not clear on how the wire inserts into the meter. I ran the wire the full length of the meter and forced it all the way into the base pf the slot. Also be aware that although the instructions refer to double sided tape, there is none provided. They do give you two small self tapping screws which you could use if you wanted to drill a couple of holes. The meter is very light in weight, therefore I used my own double sided tape to securely attach the meter, without using the screws. One other minor thing, again not a fault of the meter, is the red color. From the picture, I thought it would match the red panels on my mower. This isn't the case. If I knew there would be such a noticeable difference in color, I would have ordered black. But that's just me being OCD! All in all, the meter does the job, and I feel it is well worth the money.

    by Marjorie's hubby: I bought 2 of these to put on my snow blower and generator to track usage. Finally got round to installing one on the snow blower. The concept is simple but my snow blower engine is encased in several shrouds and it was tough to access the spark plug cable. Once I got there and managed to get the 5 wraps on, things were simple. BUT for a few moments I was uncertain how to install the wire on the unit - it is simple, just tuck the wire in the slot along the base of the unit. A little more instructions on the card would help. I held back a star as I've only had it installed for 2 days - but I like it a lot - hope it is durable. I was surprised that it recorded I'd run the machine for 2 hrs already. Now I hope to be more prompt and diligent in oil changes. I expect it will pay off in better maintenance and longer life of the engine. Now to install on the generator which also has a deeply buried spark plug..

    Hooked this up to my new Yamaha EF1000 generator and it works great. Easy to install (just wrap one end of the included wire around the spark plug wire close to the plug and stick the other end into the slot on the meter. It comes with two screws to attach it but I used double sided tape and placed it on top of the generator spark plug access hatch. Good price (half that of the Yamaha branded version) and seems to be working just fine. It has an internal non-replaceable battery and I am not sure how long it will last, but for the price if I get 2 or 3 years use out of it I will be happy.

    It works. Wish you could change the battery when it goes dead. I installed this on my generator. It reads in tenths. So .5 is 30 minutes, 1.0 is 60 minutes, 1.5 is 90 minutes and so on. Hook up was easy. Just wrapped the wire around the end of the spark plug wire, as close to the spark plug as I could, 5 times. Instructions are vague. The wire needs to be inserted the full length of the slit in the back of the meter. Does not explain this in the bad directions. If I could change the battery, this would be 5 stars. Overall I'd buy this again and recommend it to others.

    So far so good. Installed 2 days ago to a brand new echo backback blower to see how long this brand of equipment will last. Was easy to install, took ten mins tops. In the past I have used a product similar to this one and it stopped working a year or two after installing which did not help my cause any. Lets I am looking for better results with meter.

    Tracking maintenance on my generator is easy with this hour meter. Took less than 5 minutes to install. Like other reviewers, I wish the battery was replaceable - I'm deducting 1 star for that.

    I gave this to a friend as a gift for his pit bike. It was easy to install and works great. The order was placed for a blue unit, but a black one was received. We decided to install it anyways, but it would have been nice to receive the correct colored item (which was priced higher than the standard black one by a couple dollars) since I wanted it to match his bike color.

    The meter itself works as it should. However, the directions are rather poor and should include the fact that the spark plug wire needs to be free of any shielding in order to pick up the signal.

    I'm happy with this hour meter. Hooked it up to my mower and am surprised that it works since it was so simple to hook up. The wire is too short but I just used another length of wire that I had on hand.

    Put this on my Toro mower. Toro wants $60 for their meter! Installation was easy and I used double sided tape to mount the unit. I reduced the rating to 4 stars because of the sealed battery which will give out one day.

    This item was easy to install and works like a charm. Don't know how long it will last but for now it is keeping track of the hours my generator is running. Arrived quickly and instructions were easy to follow. Watched a couple of videos online about installation and 5 minutes later it was hooked up.
