Well the connector pin thing (I have no idea what it is called) is a bit loose due to the crack so I can move it a little bit which might cause a sudden interruption.
I can't post the video I've made...
Ohms were a bit high at 5.9 to 1.9-2.2, the replacement is 5.5 to 1.8. The old one was at 17.7 once instead of 5 but this might have been a faulty measurement.
The difference from old to new is low but I've changed it anyway cuz the old one was a bit... crumbly and already 50 years old.
(No I didn't pull the plug like I'd start up a lawnmower. It was already wobbly when I've inspected it last week).
I'm now gonna order two of those ignition switches you guys mentioned, just in case.
Ah yes, OEM part number is 3656199, replacement is an SMP-RU12. I've ordered 2 similar resistors, both read exactly the same if anyone wanna know.
