Throttle/Pedal Issues 2012 PH Series Precedent

[GeauxTigahs]

Hello everyone. I'm new to the world of golf cart ownership. I purchased a 2012 PH series 48v golf cart used from an individual. The speed controller was changed with a refurbished Golfarama 1515 around a week ago. One of my issues is that the cart will only start with the pedal pressed 10-15%. If you go past that the cart will not start. Also once it is going if you go past 50% throttle then cart will completely die. Any ideas on what this could be? I also did a load test with the batteries after a full charge and each one dropped around 1.5v. They are the PD plus batteries and just by judging the letter and date they appear to be 4 years old. Any help would be greatly appreciated!

After reading more on the MCOR issues I wanted to also state this is a 2nd gen pedal assembly

I am not an expert but I think you are explaining typical MCOR problems.

Try turning the key off and pumping the go pedal 20 times, and see if that has any affect on your issues.

As for the batteries they could be on their way out based on age, and what kind of care they received.

Check out this Battery information sticker if you have not already seen it:

Post up your individual and total pack voltages right after full charge and about 10-12 hours later.

No luck with the 20x pedal pump. What's strange is that you can hear the click but when you goto the floor with it, it kicks the solenoid out which makes a lot of sense saying it is the MCOR.

I'll get battery info as soon as I can. Thanks for the help

You may have an issue within the harness itself.

The Excel cart has 453Ω resistors in each of the throttle wires.

You can disconnect the 16-pin Connector from the Controller and the 3-pin connector from the MCOR and measure those resistors.

Controller Pin #1 to MCOR - White wire
Controller Pin #2 to MCOR - Yellow wire
Controller Pin #3 to MCOR - Purple/White wire

You should measure approximately 450Ω between each of those connections above.

I do apologize for my ignorance of using a multimeter. I finally got a reading from all three wires and they checked good at 450 each

I talked with another guy and he believes it's the controller too. So now to decide try to get them to warranty the controller and get out of it or get an Alltrax and call it good. Have 1400 in it right now. Batteries another 600 and allltrax 500. 2500 goal and needs a little front end work :(

On an Precedent Excel cart it is not a good investment to replace the Controller with another OEM controller, new or repaired.

The OEM Controller makes it harder to install many performance upgrades.

The best solution would be an Altrax Controller.

Thanks for all the help guys. Forums like this are an awesome tool thanks to good help like y'all. Think I'm going to consider the Alltrax
