mcor/ speed control

[johnnyreno]

just put in mcor 4 cci 105116301 part number and a new speed control part number 400a EZ NPX4844/0-5K NOW CART will only go full throttle or stop basically 1 speed mcor was adjusting speeds normally until the speed control went south BTW. THE SAME EXACT PART NUMBER SPEED CONTROLLER is what I installed. it will jump screech tires and take off and run as long as I keep feathering the pedal it will stay running and pick up speed or stop unless I keep feathering the accelerator or stop and when I press down about a inch same thing. happens rips out and I gotta let off pedal everything on the speed control was down to the tee 1 wire at a time pictures b4 and after while installing.

To scotty or TahoeDawg--For 95 micor, doesn't he need a 5k-0 throttle signal at the controller and what's the "EZ" about? Wrong controller??

Throttle Input (Factory Programmed):
•ITS (inductive)

•Resistive 0-5K ohm (+/-10%) (2-Wire)

•Resistive 5K-0 ohm (+/-10%) (3-wire)

Ordered wrong,

Plus no cart info, plus why are so many parts going bad,

1995 Elmco club car. 48 volt Did the mcor with the part Tahoe dawg said I needed. Just needed it sooner that's another story sending Tahoe dawg a silver dollar from our store for postage I o him Tahoe was very fair. Was working fine until speed control finally played out it was already known to be going bad, put in exact same speed control a new one same part. Now it's either on or off. When ya hit pedal. Btw it's not a programmable. Speed control. THX for the ideas. BTW. Mcor 4 was the conversion from the
Original that is no less Nio longer made

I was wondering if the controller needs to be sent to Alltrax to be reprogramed for the Micro 4 throttle input. It might explain a lot of trouble. TahoeDawg or ScottyB would know for sure. Or contact Alltrax phone 541-476-3565 email: info@alltraxinc.com

Turn off the key and press pedal to floor, turn on key and let up to see if it accelerates ,

glass you may be on to something here as I let up slowly it does work PROPERLY only bass ackwards if I let up to fast it screaches and tries to tear out THX

Switched the 2 center wires green yellow now goes barely half speed then dies after about half throttle any ideas thx

If You want to keep that controller You will need to use the correct side of the MCOR to get a 0-5kΩ range.

Looking at a previous thread it looks like You replaced a 3 wire potentiometer.

If You look at the MCOR, it has 3 wires, locate the purple wire, it should have been connected to B- before.

Connect the Purple to throttle 1.
Connect Yellow and Green together to throttle 2.

You can also measure the resistance off those wires to make sure I have the colors right.

From: Yellow to Green (Pedal up = 6kΩ - Pedal Down: 0.5kΩ)

From: Yellow to purple (Pedal up = 0.5kΩ - Pedal Down: 6kΩ)

From Green to Purple ( Pedal up = Pedal down = 6kΩ = no change)

If You post the actual resistance readings, we can use that to fine tune the range later if needed.

Sergio thank you very much. I just gps the cart at 31 mph The original owner was lee Trevino after researching it.
