A
  • I never had that problem before I own two of these are use them on my boat the only thing I can think of is if you have the meter or I should say the wire too close to an electrical source it could be picking it up thinking that it's actually running and it will count how long that is running for but I have no explanat… see more I never had that problem before I own two of these are use them on my boat the only thing I can think of is if you have the meter or I should say the wire too close to an electrical source it could be picking it up thinking that it's actually running and it will count how long that is running for but I have no explanation on the times I never had that happen I have two of them they worked flawlessly see less

Q

Could I wrap the wire around one of the conductors of a 110 VAC wire to record how much time 110 VAC power is applied to that wire?

A
  • My old tiny tach could be zeroed, and then reset back to X hrs that way, think it had to be single wire not cord with 2 wires.

    This hour meter is something else. Easy to install and works great. I have 2 generators and have installed on one of them with no issues at all. Got to get my other one installed.

    Just partially installed it to a new go kart engine we purchased. It worked immediately as designed/intended. When the engine goes in we will also decide on a permanent mounting location for it. Also if we have any issues in the future we'll report back, but so far happy with purchase!

    very easy to install, plenty of wire, works excellent, looks great. no double back tape in package, I used picture hanging tape rather than provided screws. wire in meter goes into the slot, instructions are not real clear.

    Very easy. Wrapped around plug wire, routed signal wire to below the air filter cover and mounted with double sided tape. Very accurate.

    It works great and seems to be tough. I have it on a wood splitter and the motor shakes like crazy and it's still going. I ended up screwing it to the air filter cover. I try to use doubled sided tape but that only held for a day. Very easy to install. It's great way to keep track of the hours for maintenance.

    Perfect addition to my small generator. Easy to install and helpful to track run time so you know when maintenance is needed. Only wish it included double stick tape to make the install easier.
