Stock coils and points?

The numbers seem good to me.  What is missing is voltage trend info while revving 4000-5000 RPM.  If it eventually stabilizes at 13.8 -ish, I wouldn't complain.

It also kinda matters if the lighting is on or off, as that can impact how hard the alternator has to work to maintain electrical happiness at any RPM.

Cheers,

Yeah, weirdly enought, these are the best numbers I’ve ever received.
But I haven’t had it out for a longer test ride yet. I’ll have to see how it responds when it gets a bit warm, since it died on me last time I took it for a longer test ride.

I’ll try to get the 4-5k trend info this Sunday!

Well, the light turns on when hitting the ignition start. I may have to install a head light switch!

Old thread but I am facing exactly the same, measuring 1.2 Ohm on the yellow wires. Did you ever get to solve it? How?

Thanks!

It's the connectors.
