I have a couple Cox pro controllers. I also have some resistors new in the package and some loose ones too. As you may or may not know these are quick change resistors, not standard type. My question is, How do I Ohm them out to check value on the loose ones? Easier to do in the handle or loose? Thanks.

Hey Joe would you have any old COX 25 or higher resistors. I will trade a 12/15 ohm? (can't remember so I will check) for one.... Also OHM check on the tabs with a cheap Radio Shack meter. You can do it in the handle but it will include the wires resistance so just open it and again check on the tabs. Make sure your are on measrue across the first band to the end band and not the brake band.

Barn, Are you talking about a standard Cox resistor? These ones for the "Pro" controller are different from the standard. I am going to post a pic of the resistor tomorrow so someone can tell me exactly where to put the probes. And by the way I still have my Fluke meter from my tech days. Don't say Radio Shack to me when doing such technical work :laugh2:

Here is a pic of the Pro resistors. How do I check the value of the loose ones. Stangely, Cox did not print the value on these.

Can someone also tell me about the standard Cox resistors so I can see if I have something for Barn,Thanks.

The ones out of the package look to be the same Joe. I'll show you one in a few thanks. I would like to find in 25 OHm if I can.

This is the old style Joe. This is what to look for on yours to check. Brake band will not be in the circuit... it's a dead band.

Are Cox controllers wired differently than MRC plunger or Parma/ Russkit controllers?

Robert, Can't say on the Parma's but I read somewhere that the hook up wires ( black and white ) should be reversed when you use an MRC controller. What say the experts?

trying to rewire and old one like in the pic, red and black were attached to the screws but the white was loose. Where should it be connected to? thanks I know this is an old post but hoping someone will see it.

Looks like it would be connected to the wiper. If I remember correctly these controllers were wired with the black wire as power.

Early Cox and MRC are consistently backwards.  RED brake wire always goes to brake band;  BLACK wire always goes to wiper arm.  White/in-power always goes to full ON band...in modern track wiring of commercial tracks.

 

I cannot say I have ever seen the 'Pro" Cox controller, but I doubt if more than the one ohm value resistor was ever made for it.  Too bad the wattage value is so low.

Just for info from the other side of the pond. I have the Pro Cox controller and the similar spare 7.5ohm resistor MIP. However, the instructions that came with the controller under Replacement Resistors are as follows:-

 

4746 2.5 Ohm Resistor       $1.50

4747 7.5 Ohm Resistor       $1.50

4763 5.0 Ohm Resistor       $1.50

 

From the writing on the Box lid and the inside tray of the box it would appear the Pro controller was fitted with a 5 Ohm Resistor as standard

Regards Allan
