Re: Got a "tiny" charging problem...
No progress today. Went back home a bit late. Same tomorrow, so I guess I will be coming back here with some news on Thursday or maybe during the weekend.

Re: Got a "tiny" charging problem...
In the first instance, you really do need to sort out why the charge lamp isn't lighting. The tests you have done suggest that the problem is in the wiring or conductors between the bulb and the voltage regulator/diode board (i.e. the blue wire) or between the bulb and the positive supply. You don'...

Re: Got a "tiny" charging problem...
Just a tip. As shown in your first pic, your brush tension spring is too 'loose'. You should wind it a full turn tighter. Remove the stator and check the inside one also. Ok, got it. I will be trying to make these spring a bit "tighter". The front one might be easier than the back, as the...

Re: Got a "tiny" charging problem...
Before going any further, check for continuity between the female connector pin in the dash plug to the blue wire at the regulator. It's the one that corresponds to your " the third one on the right " male pin in the pic. Couldn't wait, I had to test it and look what I got! Screenshot fro...

Re: Got a "tiny" charging problem...
Alright, so it happens that taking good pictures helps. By zooming on the previous one, I managed to get that the pins involved for the gen bulb are (starting from the bottom) the second one on the left, and the third one on the right. After a second cleaning, I placed the bulb and holder back in an...

Re: Got a "tiny" charging problem...
I'm going to explore this option. Thank you very much Kurt.Kurt in S.A. wrote: ↑Mon Oct 20, 2025 1:19 pm You might have a break in the copper foil that is part of the circuit. Might want to consider opting for the Kat Dash replacement:

Re: Got a "tiny" charging problem...
I have dismantled the dash again for further investigation. There was a burnt dim light that needed replacing anyway. Armed with a tester with a probe, I thought maybe I could have the lights to light one by one. Screenshot from 2025-10-20 18-52-47.png Call me dumb, but I should be able to light the...

Re: Got a "tiny" charging problem...
The stator won't produce any output until you get some current flowing through the rotor. It sounds like that isn't happening initially because of a break in the wiring somewhere. It might help to break things down into sections. For example, using the diagram above take a temporary feed from the b...
