Depending on your meter “OL” could mean overload or open line. Check at your highest resistance setting first, then drop down to the next lower setting. Like Dave say’s bad caps too. Primary winding should have very low resistance, secondary should be around 4K or so. Bad plug wires or connectors? No telling who has added their “Handi-work” to the mix!!
Don’t assume these parts are good. I have found new electrical parts that were BAD too.
