Runleader Digital LCD Hour Meter,AC/DC 5V to 277V for Lawn Mower Generator Motorcycle Golf Cart Forklift Scrubber Machine etc.

Fit just fine on my Zero turn mower. Really like the two re-settable timers.

It works and it fit right into the spot where my defective Onan hour meter died after minimal usage.If your RV hour meter has a tag with ID T42A2A2C03 this is a direct replacement. That number is not the Onan part number as it is discontinued.

This hour meter was a direct fit into my Briggs and Stratton EXL 8000 generator and fit perfectly into the existing hole of the OEM hour meter. This hour meter is working excellent.

Fit and function is correct. Not exactly like the one I removed but was aware of that prior to ordering. The only reason for 4 stars instead of 5 is that it has only been installed 2 weeks and I will have to see how long it will continue to operate correctly.

I bought this to install on my zero turn mower. There are YT videos that give good instruction and show how easy and fast it is to install. I live in Texas where mowing season last eight months, so it's had a good workout. It keeps an accurate account of hours used, which helps me to maintain my investment. I saved over $100 by purchasing and installing this meter myself.

tl;dr: the documentation for this item does not specify whether this item counts sub-6-minute intervals, but according to my testing, it does (I suspect it accumulates seconds, though it only displays in increments of 6 minutes (tenths of an hour)).Gory details:I was looking for a way to measure the accumulated time that my rooftop Heat Pump runs its Resistive Heater (aka "Emergency Heat" which consumes electric power at a much greater rate than the heat pump operating in its primary reverse-A/C heating mode), in order to ascertain (a) whether (how much) the reverse-A/C heating mode failing to "keeping up" with heating my house (causing the thermostat to turn on the Resistive Heater for backup heat), or (b) how often (how much) the Heat Pump triggers its defrost mode (which causes the Resistive Heater to be turned on while the Heat Pump runs in A/C (cooling) mode to heat its outdoor coils). Such monitoring wouldn't discriminate which of the two above triggers have caused the Resistive Heater to run, but would at least tell me how much of my electric bill comes from running it.Rather than fiddle around on the rooftop unit, I wanted to accumulate the number of seconds (or minutes) that the W2 or E wire at my thermostat has 24 VAC applied (indicating the Resistive Heater is being called for (thus is running)). I searched in vain for a "second meter" or a "minute meter" that would count the accumulated seconds that voltage was present on this wire (NB: in my install, W2 and E wires are shorted together, so there is only 1 wire to monitor).Fortunately according to my testing, this Hour Meter appears to fit the bill almost perfectly: my test was to apply 24VAC across the terminals of the meter for 2 minutes at a time, then remove the voltage for 2+ minutes, then repeat. After 3 cycles of 2 minutes on, 2 minutes off, the counter had advanced from 0.0 to 0.1 (6 total minutes of on-time). After another 3 cycles, from 0.1 to 0.2 (12 total minutes of on-time). The Job Timers feature unique to this particular Hour Meter make it possible to reset the displayed counter periodically (weekly or monthly).I still have to come up with a cosmetic way to mount this above the thermostat.Wish me luck!update: an annoying drawback is that unlike my 2005 Toyota's odometer (which has 2 independently resettable trip meters in addition to the unresettable odometer, any of which (whichever the user last selected) remains displayed indefinitely), after a few seconds this device's display switches back to the unresettable hour counter.

Compact. Made to last and simple to install. A great value for money. Super simple functionality.

Works Perfect. Installed on my Badboy lawnmower. Easy to install wires were already there.
