I have a Miller Big 40 diesel welder, I believe it is a 1986. I have had it for 10 years with no problems to speak of. Recently I started it up as I do at least once a month to let it run, it ran for about 10 minutes and shutoff. I restarted it and it runs about 5 seconds and shuts off? It will crank right back up, but shuts down after about 5 seconds. I checked the fuel pump and it is working correctly. Anyone have any ideas what could be wrong. I'm leaning toward a bad low oil pressure switch. Thanks for any suggestions.
No announcement yet.
