Oshkosh MK48 Trailer Question - MK15 or MK17 cranes?

[Valleyordnance]

Hi Guys,

Anyone got a remote for the crane on the MK15A1 Wrecker or MK17A1 trailer cranes?

I need to know what the max resistance of the control sticks are - they are linear potentiometer joysticks for proportional control. I need someone to measure one for me so I can build a controller for my trailer. If someone is willing to help I will post a build thread to help out others in the same boat. I know a lot of the wrecker trailers were scavenged and came without the remotes.

Anybody willing to help out?

Thanks!

I can this weekend. I was going to do the same thing for a M18A1 but I found wireless remote system easier, cheaper and....well....wireless.

Jeff, It would be great if you can help out.

what wireless system did you convert to - what did it run? Hard to justify $$$ for me on this thing as it is just a toy.

My control for the MK15A1 is for the winch only ( I think ) and has buttons only no joy stix. I will measure if this is of some help.

I have a Mk16 (semi trailer) winch controller that works, I need a joystick control to find the values of the potentiometer in the stick. They are a proportional control (I believe) so the further you push the stick the more it opens the valve.

Someone correct me if I'm wrong because a on/off joystic operator is cheap and easy to get

I used the Scanreco 8 Button Pocket. I got it through: http://www.ohiopowersys.com/radio-remotes.html
It is an on/off function but it didn't matter in the hook loader function I was using it for. They have systems for cranes but they get pricy. I was able to control the fast idle on the engine which gave the hydraulics two speeds.

I looked at my controller. It has 70 some pin outs and w/o a wiring diagram it would take days to find the right combination to test. I don't want to open it up and risk breaking the seal if not necessary.
