But then, once again, plugging in the transformer resulted in the display's crash. Can you associate the loss of display with any prior circuit or parts changing just before its loss? I was looking for electronic schematics of a waterproof battery controller. Briefly, when I connect the 9V battery I can navigate through the options of the controller without problems and I can modify the settings as I wish. Have you asked the factory, or do you have the reset sequence? Of course the other relay coil terminal will be the switching transistor connection. Before it there are Q23, R60 and Q26 in series. I then wrote the voltage values on the same photo. So, 12-13V arrive but firstly only the line 1 gets the current for 1 hour just an example of time.

So, D9 comes and on its cathode we have 36. I just need a sequential start of the sprinkle lines for 1 hour each, that's all. Before, there are 12-13V coming. Your current composition of the board is just filling a complete picture frame, top to bottom, which is excellent and the vertical alignment is perfect, with your picture not being tilted. There, it stops but I suppose that the aim of C5 and C6 in series is just that. Doesn't that mean the diode is shorted? And I measured even lower values on Q2 1. I have found the datasheet of a series of voltage regulators see this link:.

I've recently seen something like that on the web. Connect one wire from the solenoid to its respective station number on the terminal block and the other wire to the C-common terminal. Then I could get back to the controller, turn it off, disconnect the first 2 wires, connect the other 2 to the terminal n. By the way, what if I take out the 600Ohm resistor for connecting Q22 base-collector and I replace it with a simple wire then with no resistance? At that point great job for R5: voltage drops from 36V to about 12V. If you bridge between the very top collector connection of Q27 to its bottom left base connection with a 1k resistor, the relay coil should activate. If not, I guess it's not due to the relay itself because I replaced it after the displays' issue. The controller will record the change, i.

Are then normal those voltage values a bit more than 2V for that transistor? Perhaps by purchasing a dual timer switch with a dual relay inside, if I'm not wrong? Level the controller, then insert screws into the two lower screws holes under the terminal block. Some connections in the photo are just covered by the lines I drew. Now if we look across to companion pin 1, it's so low, that it looks like there is a short to ground somewhere along that foils path. Also you have done a superb job on the photographic coverage and side annotations, but could you take another photo of the board just like the one that we are working with. In that case, would you advise to use a resistor to make the base-collector bridge? If so, I guess it should be replaced. Your going to get to that point real fast just chasing ghosts on this one. All contacts have a voltage value, except for pin 6.

Also, to make out the circuit's logic, I drew on the front-side photo of the board the tracks visible on the opposite side. Maybe you can fill me up on that situation. The displays are currently receiving nearly 2V but nothing appears on them. It works on the second attempt. If so, I guess this problem has due to a short circuit at the relay's area likely the pin n. Back at the time when the display failed, did you do a total power down and check out all diodes and transistors in the diode test mode.

If not, I will buy it on Monday. Then Q1 cluster has no canned filter, differently from the previous areas. First, I soldered it wrong polarisation and I measured just 0,9V. Yes, my controller looks like the ones that can be viewed via the links you posted. Low resistance should indicate a defective varistor. Can you pass on their top marking codes? The second route reaches R51 on the right and C10-Q2 on the left.

Looking at the resistors left at home, I only found a couple smaller, in series, than 1k: 270+330. No, I didn't notice circuit's parts or components existent or replaced changing thermally or in other ways before the displays' issue. You are just fine on that selection of series connected resistors. No anomalies: values in a normal range. Could it be a matter of the entry voltage? But I think that they should be rather similar.

D12 rests across your 9V battery connection for reverse polarity battery installation. I hope it will be fine for a quick understanding of the operational area. I hope you can figure out something with all those lines! The current arriving from the battery stops at D10 cathode on the left of D11 but keeps flowing on the right reaching C8 and then the other components, as you can see in the photo. To be sure that I catch all, I am going to fill in between your entrys. The ideal would then be to find a way to avoid the manual switch between the 2 lines. As I said, L1, after the relay, and C5.

So I tried to make a bridge between the positive terminal and the track in front of that terminal which I scratched a bit to uncover the foil path that brings to pin 16. It's cheap but it would completely replace the current controller, since it should have a couple of common terminals and input terminals I should then connect all the wires to this device. So, perhaps the new capacitor 470 microfarad -16V was faulty before its use. Considering the current display's issue, where would you focus on eariler? My friend Google didn't found any relevant schema. At that point great job for R5: voltage drops from 36V to about 12V. For the first hour of power on, I could connect the first 2 wires to the terminal n. The controller worked fine for a couple of minutes.

If so, how to detect this condition? Connecting the 9V battery, since Q27 has no voltage, I have to bridge base-collector of Q22 6. Run time is in one minute increments from 1 minute to 4 hours. But, as you wrote, it's not relevant for the overall problem. As there was too few voltage across it, I made this reasoning: the near positive terminal of 9V battery has about 7. By the way, the last time crystal's values were 0.
