transistor Peristaltic pump number 8

[jmcadsl]

Hello!!
I need help again beacuse i have a problem with the output for the ATO pump.
Its not going 12v out when the pin goes on, maybe the transistor its ko.

I want to use the 12v out from peristaltic number 8 to activate a rele and the rele will power on my ATO pump (i think the small transistor on the board it too small for my 12vdc pump)

I need to know where its the transistor for peristaltic 8 on the mainboard to use this one.
Thanks!

Hi jmcadsl, sorry to hear about the trouble, just to be sure, you are aware the output pin is a GND and not +12v? The GND wire from your pump would go to pump 8 pin on controler and the positive wire from pump would go to the +12v pin.

If you have it correct the transistor could be damaged, for pump 8 the transistor is on the accessory board, there's 4 small transistors in a row behind the sensor ports, T9 is for pump 8.
