Frigoblock FK13

[dan22y]

Hello everybody.

Many thanks for what your doing here.

I have only the schematics for the electrical box (near the refrigerating unit), if some one else , please help me with the rest of them, for Frigoblock 13 (the electrical drawings for generator and the plug for the 3 phase power supply)?

The mail adress is dan22y@yahoo.com

Best regards,
Dany

Look inside the electrical junction box for the drawing number. It should start with 98.
Once I have the full number I can look it up for you.

Maybe this would help: on the wiring diagramme that i have, is wrote on the right down corner the Z-NR. 96-1220, and the year i suppose: 2.11.89
I will look also for the drawing number in the electrical junction box.
My problem with the refrigerating unit is that the 3-phase alternator i think is broken, because doesn't work. It work only with the mains power suplly. I check the diodes on the alternator and all it is ok.

Check that you have voltage to the unit (12/24v)
Check that you have voltage to the generator (12/24v)
Check the shunt in the generator (between points 4 and 6)
Remove the diodes and bench test them
Remove the cables on the rotor and test with a megga
Remove the phase kables from the stator and test with a megga.
If that is all good it could also be the klixon (overheat protection)

Thank you for your suggestions, but i don't have the schematics drawing for generator, and from generator there are 3 cables with a lot of wires. And i don't know which wire to measure.
When you say unit, you refer to the unit where all the automation is realize? On the truck, near the compresor and other?

Remove the diodes and bench test them.
I tested the diodes and all are fine.
