OK. Help needed. Ford Lehman 120: My engine alarm stopped working so I ordered and replaced the high temperature alarm sensor and low oil pressure alarm sensor from American Diesel. Replaced both and alarm sounded. After a short trip, 3 or 4 hours, stopped engine and no alarm. If I ground out either sensor the alarm sounds. If I ground out the main wire running from the sensor to the alarm the alarm sounds.. Replaced new sensor with old one and still no alarm. Ideas please?
