520hC-120 136 #1 Posted October 2, 2017 When I am about to start my 520H and just turned the key to the run position without it running the oil press light will blink over and over, when I am running it it turns off but if I press the test switch while running it's there again. Just wanted to know if this was anything to worry about and if it could be bad for my 520H. Thanks Share this post Link to post Share on other sites
littleredrider 409 #2 Posted October 2, 2017 When key is on it's normal. Mine does same thing. Blinking while running might be different. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,274 #3 Posted October 2, 2017 The oil lights all flash to get your attention. The test switch is there so you can make sure the lights are working. Once the engine oil pressure comes up the oil light should go out. If the oil light is on with the engine running shut it down and find out why it is on.
