![]() So, I'd say that if you disconnect the points / condenser from the LT coil & put a multi-meter set to Ohms between the LT coil wire and ground you should see a small resistance, which will be the LT coil. One way of stopping these engines is via a switch which grounds the LT side. The HT makes the circuit via the spark plug & the LT via the points / condenser. Help me, please! I have a MK25 but cannot remember exactly how the wiring goes, sorry! From memory, both the HT & LT coils will be connected at one end to the engine block by some kind of shared internal connection. I am very new to old engines and have no engineering background. I can nothing say about the quality of the permanent magnets in the flywheel but it attracts screws which stick there. Maybe I am not turning the flywheel fast enough by hand to create a spark, at least I should 'feel' current when I touch it, no? Somehow I have the feeling as if no current get's induced into the LT windings of the coil. ![]() Actually when I touch the HT lead and ground and turn the flywheel I 'feel' nothing. Ground between flywheel stator plate and engine fine. New condenser (untested though) HT lead test with multimeter, fine. Points distance set to about 0,4mm, flywheel set to open gaps when about 4mm below TD. When gaps are closed, there is current (shortened), when gaps are open, no current. ![]() LT lead soldered to coil and leading to gaps, tested with multimeter. I have a Villiers MK25 (4 Stroke!), new coil, measured with multimeter, resistance is fine. ![]()
