Ignition Coil Readings - Peugeot 103

Damien Hugoo /


I am still troubleshooting my ignition. points & condenser appear good. Now I am testing Ignition Coil. I get a reading of 4k Ohms on the secondary (Primary reads good at 1.1 Ohms )

Listening to French videos about ignition, they say it should be at 2.5k Okms on secondary.

Does it mean that I need a new Ignition Coil ? I don't get how I have a higher resistance and if it's an indicator that the coil is bad.

It looks like the floated brake light feature is just soldered straight to ground what were you going to do about brake lights?

Treat land has two options that will bolt right in that you just solder or twist on a new spark plug cable to run out of the stator plate. The only problem is neither one of them are set up for brake lights. I took one of the orange/gold ones and soldered my spark plug cable to the tab then I was able to dig out the other end of the coil and solder on a wire to run out for my brake lights

I have another coil for lights I think (see picture). You are right, not sure why this is soldered to the ground. Maybe that is what is making reading read a higher resistance than what it’s supposed to.

I am still debating ordering a new coil or redoing the soldering or upgrading to cdi

Those r always bad. Take a read on myrons page. Although your points are waaay offset.

To run brake lights w new coil you will needs some new brake switches and rewiring.

If you decide you're going to go in a different direction ignition wise I'll take that stock coil off your hands
