Some time ago I purchased two hour-meters and installed on one my 3414.
It was a simple mechanical clock and the hook up was simple. The other one I intended to put on my B112 but never got around to it; first because I had to cut a hole and secondly it is digital and the installation isn't as straight forward.
I understand (assume) that an always hot 12v+ is attached to spade #1 and a ground to spade #2, I presume to provide a continuous display. Then another switchable 12V+ is attached to spade #3. Since the display has to be on a minimum of 5 seconds before a signal 12v+ is supplied to Spade #3 than I would suppose that 12v= can be supplied by the L or A circuit or on my 916H the I circuit on the ignition switch. Is this correct or could I just supply power to #1 & #3 simultaneously? Please help me interpret.
BTW: this is product #701.

If you apply power all the time to terminal 1 with a corresponding ground or neutral to terminal 2, and terminal 3 only when your tractor is on, then your display will be on all the time. It will of course only add hours when the tractor is on. This will allow you to read the hours without turning on the tractor. However it will also put a very slight drain on the battery which may or may not be a problem for you.
The other choice is to jumper wires 1 and 3 together and feed it from a source that is only on when the tractor is on. Then you will not have a slight drain on the battery when the tractor is off, however you won't be able to read the display when the tractor is off.
sounds good... i was wondering a bit here... |

I'd say our on the right track. Simple schematic would have been a big plus.
