Motobecane ignition

I have a 1979 Motobecane mobylite 50v I was wondering if anyone has ever seen this. I lost spark. Did a new wire and have a new ignition coil coming in the mail I’m hoping the ignition coil comes in. But does anyone know where I can get new internal from that’s like this?

You cleaned the points? The condenser really sux too...

Re: Motobecane ignition

Very rare that the internal Novi coils die. Check it with a ohm meter with the wire disconnected from the points and the iron core near the tail end solder (not on the solder but near it) it should be 0,5-1,0Ω ±10%

I would suspect the bonding strap (between the engine upper mount and the external coils lower mount stud) they are crap (replace it anyway with a new wire going from a intake stud up to the ext coil lower stud).

Next check the condenser (also a good idea to change anyhow to an external one mounted at the ext coil lower stud, wire the pigtail to the grey coil wire, disconnect the original), followed by the antiparasite plug cap (NGK LB05EP perfect substitution), then the external coil (if the external coil looks chalky or dry or has a crack replace it).

If your internal coil tests defective you need to google "bobine allumage" for Mobylette or MBK or AV88 (etc) and pick your favorite frenchie supplier.

Alright thanks guys. Condenser will be getting purchased this weekend

Re: Motobecane ignition

if it looks oily in the stator area id order new crank seals as well.
