Problems wit my orange b: in English

[CugelQ]

Dear friends / Amici barchettisti I have som serious engine problems with my orange b. and need som really good advices!
Problem as follows:
Doing renovations during the winter, new camshafts, brakes and more. Changed bearing in the alternator could,t stand the whining anymore, the job was a real challenge.
So far so good, ordered a time for MOT (Besiktning in Swedish).
and on the way the injection lamp begin flashing (not at steady light just a erratic flashing, engine cuts out.. restart, and drive for a few hundred meters then again it cuts. (ends up towing the b to my house instead).
Once home again I started the faultfinding, jacked up Fiat ECU Scan started and the results was, text below from Fiat ECU Scan:

RPM/TDC signal anomaly:
check
-harness connection state
-sensor
-continuity and sensor resistive value (500/700 Ohm at 20 C). between pins 33,41, 35 of the ECU wires bundle connector and pins 1,2,3 (shielding) of the sensor connector; moreover, check the insulation of the two grounding conductors, while pin 3 of the connector has to be grounded - signal emitted from the sensor (between pins 33 and 41 of ECU) with the engine started or during the starting attempt, by means of an oscilloscope.
The reason for this fault is Value too low
The current status of the fault is
The error counter value is 20
Jacked up the b, removed the RPM sensor (situated right under the starter) checked it and it appears that the cable was damaged, may have happened when I was poking around in that minimal crowded space to remove the alternator, (had to take out the starter before the alternator).
cut away the cable, soldered on a new, measured the sensor and it seemed OK, giving readout on the multimeter (500 + - Ohm)
Restart, grinding on the starter for a while and the engine comes to live again, then results from ECU scan:
81 RPM sensor no signal
Tore away the timingbelt cover and visually inspected the TDC sensor situated next to the exhaust camwheel, and it looks good to me!
I just been checking the wire harness between the RPM sensor and the TDC sensor to the Hitachi ECU, no problems with the conductivity = OK.
(Disconnected the ECU before of course).
How common is it to RPM/Crank sensor stops working, have any experience with this error? Maybe I´ve smashed it when I removed the starter?
And the TDC/Cam sensor any experience with malfunction here?
I´ts a Hallsensor and cannot be measured with a multimeter.
Thinking seriously to get and connect an oscilloscope, check the signal pulses from those damned sensors, or should I just order a new RPM sensor?

Test again with ECU Scan new result, text below from ECU Scan:

Phase signal anomaly:
Check:
-continuity and insulation on the conductors from the sensor connection to the ECU wires bundle connector, and mainly
a) pin 2 sensor - pin 34 ECU
b) pin 3 sensor - pin 42 ECU
- positive supply from the ECU relay for the sensor (12 Volt), ignition ON, on pin 1 of the sensor connector.
- signal emitted by the sensor between pin 2 and the ground, by means of an oscilloscope (square wave) the engine started or during the starting attempt.
NOTE: the lack of this signal during the engine functioning causes the lighting of the anomaly lamp in the board, while in case the signal is absent during the starting phase the engine does not start.
The reason for this fault is Open circuit
The current status of the fault is Impact occurred
The error counter value is 1

Any good advice would make me in a better mood!

Hi, I think to myself maldas the camshaft sensor is the so what we had just recently here.

First time check the connecting plug and wire from the camshaft transmitter behind the inlet gear.

If everything is all right i think you must change the transmitter

Thanks Antenne and Georg, sorry for writing in english but my german is far worse...

Just as the post listed it´s probably the Nockenwelle sensor, and to be sure I have ordered
the two sensors (RPM & TDC) from barchettaparts Henk in Holland.

As soon I get them, write back for the results..

Once again many thanks to you German barchettafriends.

Mit besten Grüßen

Hello Cugelj no problem in it englisch.Wenn we can we help you and we hope that running then your Bella again.

@ CugelQ

you may be sure.....your german is much better than our swedish -  Skål is all what I know

I'm pretty confident that my english is quite good - but what's an "alternator" in a car?

Alternator sollte die Lichtmaschine sein.

Hello Cogel how far you are now with the deim problem because we have not heard from you for some time you have changed the sensor? And there is the problem yet?

Greeting Georg
