Last year I did a Berryman's soak of the oil pan and my intermittent low oil pressure warning never came back...Until today. I hooked up my small travel trailer (14 ft) and plugged in my 7 pin connector. The engine started running a little different after it was plugged in but I just figured it was the house battery in the trailer charging from my alternator.
Hooked up the trailer, safety chains, double checked the 7 pin to make sure it was secured in place and headed towards a welding shop about 20 minutes away. I'm looking into adding a receiver hitch onto the back of the trailer.
About half way there while sitting at a stop light I got the low oil pressure warning. At the same time the needle would drop to zero. Then it would go back up and the warning would turn off. It did this a few times while sitting a the light. It was almost like an intermittent type electrical connection.
Once I started moving, the oil pressure would go back up and would stay fine. Then I would sit at a light for a few minutes and it would show up again. But not stay on for more than a second or two. Again....like a bad electrical connection.
I double checked the oil level, it was fine. Maybe 1/2 quart low. Drove home. Unhooked the trailer. Went back out on the exact drive. Stopping at red lights. Everything is fine. Pulled over and let it idle. Everything is fine. Put another 20 miles on it. Start stop, idle, driving all speeds. The oil pressure is steady. 40 psi at idle (I know that's not actual) but running at 45-50 mph I'm seeing 60-70 psi on the "quasi" oil pressure gauge.
The trailer has a standard 7 pin connection. Trailer brakes and a wired in a Prodigy brake controller to factory supplied leads.
All I can think is there might be a loose connection on some of the pins/connectors, drawing current, and somehow affecting the oil pressure sensor or gauge.
Tomorrow I'm going to clean the connections better and make sure connections are good and snug. Any ideas on this would be appreciated. Will keep everyone post tomorrow after I take it out again. Thanks for listening!
