I did this fix on my 900 to prevent the hour meter from running with just the key on. Think it was from this site that GrapeMan originally posted.
May just work on the 1140.

Hi I'm a new member to your forum. I have had my RTV for 15 months now (love it more everyday). I have been reading your forum for a year and a half. I find it very very interesting and informative. I think I have an answer to one of you guys questions. Running the hour meter only when engine is running. Two different times my key got left on adding 4 hours to my meter! Here is what I did.
1. Make up new 6" long wire with fuse holder+1/4 amp fuse, with femalespadeconnector on one end
On back of hour meter disconnect (red/yellow) wire and leave it disconnected
On the back of the Battery emblem is a lightsocket, there is a (white/red) wire (mine is marked #2) splice the new wire to this wire and connect it to the empty terminal on the hour meter.
I have run mine this way the last 20 hours with no problems.
The #2 wire (white/red) on battery indicator light,comes from the alternator to the battery indicator light and
is positive 14 voltsonly engine is running.
