I have just bought this hour meter... DC HOUR METER 12-48V (hexagonal casing) UF17305017 | eBay
I want to wire it up to my 2012 50hp Tohatsu TLDI engine.
It has three pins on the back and wiring instructions are...
V+... Operating voltage
V-... Common (ground)
I... Enable (Optional, use operating voltage to power this pin to record elapsed time (701) or increment count (703).)
and in the auction it says...
3 pin Device (positive, negative, I Pin. The I Pin needs to have system voltage applied to it on the first use for it to feature on the display)
I am not very good when it comes to electrics, so this is what I want to know, how do I wire it up?
Am I correct in thinking its just a wire to the positive and a wire to the negative terminals on the battery and for the "I" pin, connect that to the ignition?
Is this correct? If so can anyone tell me which wire is the ignition wire I need to tap into from the control box/ignition key?
Here is my manual online... http://www.tohatsu.co.jp/en/boat/pro...body_houmu.pdf
I think page 31 is the most appropriate but I am still not sure which wire is the ignition wire?!
Thanks very much,
