I just realized I did something really stupid.

To turn off the MBR I unplugged the connector I placed on the "power" however there was also the ground on the same connector.

Basically, the headlamp was turning on as the MBR was grounding through the lamp.

Properly grounded, the headlamp does not turn on.

In any case, there is voltage on some pins of IC2
Pin2, 3 and 15 are at 2,1V and pin16 at 9,15

No significant voltage on any of the IC1 pins and on the Out I can measure 12,3V with an input of 13,6
 
This device is again giving me problems - the secondary battery is not charged:eek:

With the lamp I used last time, I measured the output voltage and it's around 8V with the lamp on.

Voltage at Q8 (that was failing last time) is, @ pin1, 29,6V when turned on without the lamp and drop to 16,4V with the lamp connected. If I disconnect the lamp, the voltage goes to 18,4V and not to 29,6V and the green led (charging) stay on.

This is really strange.

By the way, I already replaced Q8 with a brand new one, just o be on the safe side.

Any suggestion?
