FCM Problem ::FIXED::

[Richard L]

Please remove this transistor. This transistor does nothing useful. It is intended for a handheld tester but never put into production.

It worked! Finally. After removing the transistor voltage jumped to 7+V and everything is functioning properly. Thank you very much, Richard, problem is resolved at last.
So is it ok to run system w/o this transistor?
Tomorrow I will try to make a test run to be sure everything is fine.
Thanks again!

It is good to know. This is a difficult one to trace but with your help, we did it. Thanks for your patience.

This transistor is for communicating with the handheld plug in. It has never gone into production. Its function is to tell the unit the status of the system, output to the user port. No other functions to the main controller circuitry.

Sorry, but seems like I'm having another, former problem here.
Re-installed and rewired everything and prepared for test-drive, but when I tried to enable "TST" mode I found out that water is not coming out of nozzle. Pump was working, all led's were lit, but also "Water level" was let on the gauge. "S" is lit, but no bars. Again, green led is not lit on red connector (yesterday it was lit, which is strange).

As you remember we've soldered brown and black cables in FCM, so I've opened it again and resoldered them as it was initially - no effect. Some area on pcb is extremly hot if it matters (dunno whether it should be like this).

After this took a car for a ride and put a nozzle pointing directly to windshield in front of me. Went to full boost - no water coming out, but noticed that "B" letter on the gauge is lit while on full boost.

Any suggestions for possible reasons for this? Really sorry for bothering you again.
