I have a PDM 15. Output 3 is on when it shouldn't be. Can't turn it off.
Bit of context. The PDM 15 is wired into the car. 12 key Blink Keypad connected and outputs 1-9 are currently wired up. I have updated the firmware to the latest version and uploaded a blank configuration file. Regardless of what I do Output 3 outputs 12v when powering up the PDM. Output does not ever turn off.
The PDM even says the output is off in software but when connecting to battery output 3 becomes live.
Any ideas what to check or should I get the unit sent back for testing/repair?
Hi Gideon,
This is likely a failed output. This failure mode tends to occur when a larger voltage spike back-feeds the output and overcomes the suppression diodes. What was this output connected to? Email us and we can sort out a repair FOC.
Not a great deal of help but I have a 25+ and also have the same issue. Exactly the same, always on even when deselected. Luckily its just the side lights so not a great issue but not been able to rectify it, been the same for over 18months. Didnt even change after the updates.
