Sure enough . Being it off you might as well get the count. I am pretty glad that you started this thread and we are making some head way. not really sure how finding the APECS 4500 will be it seems I looked at fleabay again and now there are only the 2 from china on there

Yeah I am not in a big hurry either but would like to compete. I have plenty of other projects to work on until I find a controller. I do not know if i have a computer that will work on the software
I have found a site to order the connectors with the sockets that plug into the controller and the socket removal tool. Will need the DTM06-SA and -SB.
www.deutschconnector.com
Deutsch DTM06-12SB Plug Assembly | DeutschConnector.com
Deutsch DTM06-12SB 12-Way Plug Assembly, Black. Complete with wedgelock and choice of sockets. Mates with all DTM04-12PB Receptacles. DTM Series connectors are rated 7.5 amps continuous and accommodate wire sizes 16-22 AWG.
This seems to be convenient timing. I have been speaking with tech support at Parker Services. They are dealers for the APECS 4500. They have been incredibly helpful, but we are still trying to figure out the best path forward. I borrowed an oscilloscope from work and measured the signal coming from the magnetic pickup (MPU) on the PTO and the signal going to the actuator under the hood.
Here is what I found. When the generator is running at 60Hz with no load:
The MPU is putting out a signal of about 475Hz sine wave with the signal oscillation from +12V to -12V.
The actuator under the hood is a DYNA 8000 and needs a pulse width modulation signal (PWM). This signal for me was a 373 to 375 Hz square wave, duty cycle of 61%, and a voltage from -1V to +8V. The duty cycle changes the actuator position. so this could be a little different based on the linkage setup for each truck.
So far we have determined that the 475Hz signal from the MPU is a low frequency for a typical engine governing signal. We are looking at other controllers that may be more simple and require less programming than the APECS 4500, but the 475 Hz frequency is not common. typical ranges seem to be from 500 to 11,000Hz based on manuals I have read. Below are pictures of the signals. The DMM on top is the Hz and voltage coming from the generator.

Sounds like getting this worked out is going to get expensive. Makes one wonder if that someone like a dealer might be able to program the unit for us
