Hour meter on a case 850b

[Beer man]

Replaced the hour meter on my case 850b. All went well....I thought. Meter worked fine...one small problem is that the meter runs even when the engine is not running. Is there a switch on the engine that may be sticking? Reaching for straws!!

There should be an engine oil pressure switch located behind your dash. This allows the hourmeter operation & alternator charging to happen only while engine is running

What would cause the hour meter to continue to run when the engine isn't ?

 

[alrman]

You have it connected to a constant power source ..... how much beer is involved in this repair??

 

[Beer man]

Always beer involved!!!! I disconnected the old non- functioning hour meter and plugged the new one in. If the previous owner didn't screw with the wiring ( I noticed the hour meter was a replacement ) is there any other possibility other than a direct wiring job?

This is what it is supposed to look like - switch in red ; hourmeter in green & wires in between

 

[Beer man]

Where might the oil pressure switch be located? On the top of the engine or??? Thanks for your help!

 

[alrman]

There is a rectangular plate, between the bonnet & operator grab rail..... directly above/behind the dashboard. It lives under that panel.

Thanks! I'll be on that on my day off.

I found the oil pressure switch and the hour meter is wired correctly. Is it possible that the switch is stuck on? If so is that switch particular to Case or could I find one at an auto parts store?

Beer man - first tool required by anyone undergoing any sort of electrical repair- a test light .......
Yes, the switch maybe stuck & yes, you can buy one anywhere

Thank you. I feel confident that is the problem now that you've given your insight.
