L555 Hydraulic Temperature switch

[Dwain]

I believe my hydraulic temperature switch (part # 265617) is bad. As soon as I turn the key the first click, the light comes on and stays on with the machine running. I presume it is a high temperature warning. They are single wire switches. I need to get some specifications on the temperature switches (2) on my machine. Such as, what the resistance reading should be cold, etc. I have the service manual but there is nothing in there about it. Will the Operators (Operation) manual give me this information? If so, which manual (Jensen, etc.) is the best? The coolant temperature switch (mounted by the thermostat housing) and the Hydraulic oil temperature switch (mounted in the tank by the screen housing) are the same part number. Can I switch these out? Any and all help is appreciated. - Dwain
