Customer Question
My generac mdl...

My generac mdl 004451 shuts down anytime a load is placed on it--otherwise engine runs fine ---oil pressure switch was disconnected years ago -

Mechanic's Assistant: Can you guesstimate how old the engine is? And has it done anything like this in the past?

14 year old but used very little - - problem surfaced about a year ago --runs and idles fine - just won't take a load anymore ----- shuts down INSTANTLY under load

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes--I have a knowledble person to help - just trying to diagnose WHAT sensors tell it to shut down so we are not tossing parts at it

Mechanic's Assistant: Anything else we should know to help you best?

Trying to narrow it down to WHAT specific components tells it to shut off, besides the oil pressure switch
