INPUTS SHOW UP AT 6.00V
Just started getting this PDM 25 installed and running. Google search has not come back with an answer but all my inputs show up at 6.00v and they are 14+ ish actual. What should i be looking at to correct this?

DC motor polarity reversal with a twist
I have an idea to enable the use of an Estopp electric parking brake actuator via the keypad instead of the button and control module that comes with it. The actuator only has two wires so I am assuming that the parking brake control module reverses polarity to the actuator. There is no limit switch or anything that would break the circuit so I assume module turns off the power to the actuator based on amp draw or based on time. My thought is that I can wire up two relays with each one providing ground to each wire to the actuator in the normally closed position. Each relay would be on a separate output in the PDM. Then when I activate one output or the other to apply or release the parking brake, it will provide power to one of the relays and energize the relay at the s…

I just did this. If u have a pdm 28 the outputs are reversible and make it super easy. And I used a combination of on time and amp so that way if it dosent hit amp cut it will still turn off the output. So basically u can set a line of output on time is < x amount of seconds and output current < x amount of amps super easy holes this helps
Updating Firmware on my PDM25-V3
Trying to get my PDM loaded with V1.2.3, I'm getting the "Device is not responding to the Bootloader". Any help would be amazing.

Brake switch, line lock and trans brake wiring
FT600 and Hardwire PDM.
I have wired the components per Fueltech's wiring diagram for brake switch, line lock, and transbrake. Is it best to wire an output from Fueltech to a Input on the Hardwire PDM to control all the functions? Any other suggestions on wiring is appreciated.

IDK if you can get the PWM duty thru can, but if you can, instead of using a SSR, use an output driven by the PWM duty readed in the can bus.
If not, maybe you can figure out how read the PWM duty with an input in the PDM, and drive the output with that value.

THe original units measure 0-6V. You can still program all your logic, apply battery voltage, but it will only show 6V.
