A brief (well maybe not so brief) explanation of the electrical hook-up on the Bobcat attachment system is presented. It explains the options and how they work, or do not work. This confusing mess has been verified with Bobcat engineers directly and not the ill informed Bobcat dealers. Now you too will understand this totally confusing system.
1. - Bobcat 7 to14 pin (P/N 6706392), and 14 to 7 pin (P/N 6706391), pigtail converters. These converters exist as Bobcat part numbers but are used for older systems using the old style 7 pin "trailer connectors", not the newer 7 pin digital connectors as used today. For all practical purposes they are of no value in hooking up any type of attachments except perhaps series 40 and 50 loaders.. The reason will become clear as you read on.
2. - Bobcat 7-pin connector kit system. This stock connector kit consists of Bobcat P/N 7128426 kit which costs about $152 at dealer cost. This connector works in conjunction with the Bobcat attachment mounted solid state controller card. The connector carries ground, a pin of 12 volts, and digital data only to the attachment mounted proprietary and programmable Bobcat controller card. It is of no value to anything other than Bobcat engineered attachments since it must work in conjunction with the proprietary attachment mounted Bobcat controller card. The physical control of the 6-way (3 cylinder) blade is a cab mounted 3 position selector switch and a single 2 position rocker spring loaded to a center no contacting detent. It is a 2 switch system which the controller card on the blade decodes to the proper valve (of 6, 2 per valve) from digital data.
3. Bobcat 14-pin connector kit system alone. Consists of Bobcat P/N 6733136 kit which cost about $345 at dealer cost. This connector/system works in conjunction with non-Bobcat attachments, all of which do not have a Bobcat proprietary attachment mounted controller card but rather do have 12 volt mounted solenoids alone (6 [2 per valve] for a three cylinder attachment). This kit consist of both a cable and more importantly a Bobcat mounted controller/converter card (a sealed black unit with three connectors on it). This Bobcat mounted (not attachment mounted) controller, converts the digital signal intended for the standard 7-pin system into numerous 12 volt signal outputs only. They call it a digital to analog converter for lack of a better name. There are no digital signals on this system beyond this included Bobcat mounted (not attachment mounted) sealed black controller/converter . This kit is thus intended to interface cab mounted controls to 12 volt outputs only on specific receptacle pins, for control of the attachment through direct 12 volt (only) outputs. There are actually 5 receptacle or plugs on this unit, three of which connect to the Bobcat mounted controller (converter) card. This is why it costs $345 dollars.
This will not work with the newer 7 pin systems, nor is there a simple pigtail converter. This unit carries 12 volt signals only and does not interface to the attachment mounted Bobcat controller card on Bobcat implements.
4. Bobcat 7-pin and 14-pin connector kit system. Consists of Bobcat P/N 6727739 kit which costs about $400 at dealer cost. This kit contains both item 2 (cable alone) and item 3 (cable and controller/converter) above, and also interconnects to itself to self-detect if one is using a 14 pin direct 12 volt solenoid control on the attachment, or the Bobcat digital controller card system on the attachment. This is the grand daddy of interfaces.
====================
The 14 pin connector/converter system as described in items 2 and 3 above is intended for third party attachment providers who need complete direct 12 volt actuation control. At this time there does not exist any "pin-out" drawings for this system within Bobcat, but they suggest using a voltmeter and actuating various switches in the cab to determining which pin gets "hot" (12 volts) in relationship to the particular pin being read by the voltmeter. A simple 12 volt test light will also work.
In effect, both Bobcat and non-Bobcat attachments can thus be interfaced to the cab mounted Bobcat controls. These kits install to all skid steer and track type Bobcats manufactured to date.
In my case I am purchasing the dual pin-out (7 &14 receptacle) unit w/ controller/converter (Item 4 above, P/N 6727739 kit) on a new T650 so that I can use all attachments made whether Bobcat made or third party made, while still controlling the attachment with internal Bobcat cab mounted controls alone. In my case they are the premium joystick controls
Regardless of what the dealers tell you (which is mostly wrong), according to the Bobcat engineering department, this is now the system is intended to work, and the hardware offerings provided to do this job. Items 2, 3, &/or 4 takes about 40 minutes to install yourself, so I'm told.
Frankly, I would have rather of had a root canal, as to pry all this out of Bobcat. In fairness, one person Mr. Robert Osborne at Bobcat, a District Rep. was very helpful at getting to the bottom of all of this. Even he too, had to do some research and then properly explain all this to his dealers who are about as much in the dark as you and I.
The bottom line.... You must either have a Bobcat attachment mounted controller (which only comes with Bobcat attachments) and a 7 pin Bobcat attachment kit system, or you must have a 14 pin kit which includes both the cable(s) and a Bobcat (on the machine) mounted controller/converter, in order to get cab controlled 12 volt outputs to that 14 pin connector. And for about 400+ bucks you can buy both in one package ( P/N 6727739 kit) !!!
Whew !!!!!!!! No wonder people buy Case and Caterpillar, etc. No where that I can find does Bobcat explain any of this.
