FCM Problem ::FIXED::

[Richard L]

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.

On to the next problem solving.

The Brown wire modification should be permanent. Please "reinstate" the modification, brown wire from the 8-pin connector to black wire of the inline valve.

I cannot work with you if you keep making modifications before telling me. One step at a time. You are again telling me too many things that you might think useful but unfortunately it doesn't help, just add more confusions.

Let me know when you have reinstated the modification.

Ok, will do. Should I also take out restrictor as well as you asked on page 2 (currently 0,9 restrictor is installed)

[Richard L]

The next three steps only:
(Check there is plenty of pressurised water in the inlet of the FCM (6mm) first.

1) Remove the restrictor (as you suggested)
2) Remove the 4mm hose on the outlet of the FCM
3) Put TST link on, let me know if you have water coming out of the FCM.

[fplucid]

Conducted all the steps. Water is coming out from FCM.
Strange... so this should mean that nozzle is blocking the water?

[Richard L]

So good so far.

next steps:
4) Whilst under TST with open FCM, can you see any bar display on the gauge?
5) If yes, put the same nozzle (previous test) in the outlet of the FCM, How many bars is the gauge displaying

wait for your results

[fplucid]

4) no bars, water level led is lit, water is coming from FCM
5) same, but water is not coming out from nozzle

[Richard L]

OK, we will look for the display problem first:

6) Is the FCM box fully closed?
7) Does the gauge show "S" when the red harness is plugged in?

Meanwhile, disassemble the nozzle and clear the clog. You need two 10mm spanners and a 1/8" flat blade screw driver.

[fplucid]

6) No
7) Yes

Ok, I will clean the nozzle, close the box and will try again.
