Good Afternoon, I’m working on starting this 1986 BMW 325e. The fuel pump turns over anything electrical comes on the starter is getting power but it’s not clicking I have jump the starter all my fluid levels are full. I’m sending you a picture of the back of the starter my dad has a blot missing and you’ll see it in the picture do I need that blot in order for the car to start?
Hello, I’m assuming that the battery is fully charged. At the starter you have to check power to the thick red wire, it should have power all of the time, what turns the starter on is the black/yellow wire, it should have power only with the key in the cranking position. If it does not have power you’ll have to check the same wire at the ignition switch, it should have power there only with the key in the crank position. If there is no power coming out of the switch make sure that there is power going in. If there is power into the switch but not out the switch is bad. If there is power out of the switch but not to the starter then you will have to trace the wire and check it for power along the way to find out where the break is.
You should really have a wiring diagram for it if you don’t already as there are switches and relays in that circuit. Hope that helps, let me know if you have any questions. Thank you.
