new mcor4 conversion, no go

OLDESTCOWBOY

just installed mcor4 conversion kit AM293101, does not work and gives
code on led on alltrax of 3 red blinks. (indicates high pedal disable,throttle has
not gone to zero during this power on cycle). I disconnected mcor4 from rail and tried to make it work, but I still get the trouble code from controller.
Does anybody have any ideas how to bypass this?

You can disable HPD in the Alltrax software. (if you have the DCX model) It sounds like the micro switch in the MCOR might be stuck closed. Put your ohmmeter across the connector with the two pins(the male connector end) and see if the sw opens and closes as you depress the go pedal.

The new style MCOR3 and 4 are hit and miss with the Alltrax. The signals on most of them are just not stable enough for that controller to process. If you have any access to any older carts for parts and can find an MCOR2 that is the best option other then going back to a Curtis.

Not being a smart-*** or anything but do you have a reference for this.

Is your cart a series cart now?

What are the blinking led counts (indicates throttle type) when you first power the AXE controller?

How do You have the MCOR wires connected to the rest of the cart?

My reference is experience...I have seen them work perfectly with a MCOR2 and not function at all with a brand new MCOR3. Its no secret that many of the mcor3 have inconsistent ohm signals compared to the mcor2. THAT is why people are having so many throttle problems since mcor3 came out. You can verify it easily yourself with meter on ohms and leads on purple and yellow and see the signal does not respond exactly to pedal movement but bounces all around even when pedal is not moving.
