Happy fixing time again. No photos.
Yesterday I was on my way home on the motor bike and suddenly the cockpit went away. No speed, no RPMs, no fuel gauge, temperature, turn signal, gear indicator: nothing. After I realized the lights went dim and the cockpit showed the ABS light, I got in a hurry to get home. Modern bike can't switch the lights off to lower battery drain
Just in time, as shortly after I got home the motor began stuttering and off it was. Drained battery to less than 8V.
As the battery is old, I recharged it. Trying to do so with my power supply (bloody HAMEG, now Rohde&Schwarz, manual explicitly states battery charging is possible) the PSU went *POOF*
Had to use the old style charger from the garage.
So today I measured with the clip-on ammeter the current. No charging when motor runs, but abt. 16A draining. Time to make her naked, manual says to take off the right side cowling and then you have access to the regulator. But on my machine the cables and connectors where all different and I had to remove both sides of the cowling, the tank, the air filter and with a lot of swearing I managed to disconnect it (a hybrid of a piano player and gynecologist could be helpful). Measured the generator and it seems to be fine. Diode testing of the regulator shows no sign of failure, but a more in depth testing revealed the regulator to be more a kind of 6V reg
So just dropped an order for a new one, this time I will route the cables different so I have better access to it.
SWMBO told me yesterday: vacuum cleaner stopped working, intermittent operation, the cable went south. I told her to rip it apart, gave her the Fluke handheld and instructed her to locate the failure. Was about 1m from the cleaner, snipped off the cable, crimped on new connectors and she put it together again. So now the cable is a bit shorter
The PSU has blown the pass transistor and vaporized the shunt resistors. Have to order...
