The lower access level handhelds don't show faults? I have always had the OEM level.

Yes, but they cannot be used to view and adjust the PWM settings if needed.

It is my understanding that the newest RXVs actually use a 48v solenoid now. And your conversion kit should have came with a matching solenoid. I bet it is just settings for the 48v solenoid that was supposed to be included with your kit.

When I did my conversion it came with a 48v solenoid and the 1206AC-5201 Curtis controller.

Even the -5201 can be set to 100% pull in and 78% hold in for Main. Nominal values for a 48V solenoid in an RXV.

It sure can, and this is my best description of why voltage was set too high, and heating.

Thank you all , I agree it's a control PWM signal problem . The manufacturer changed the default solenoid PWM to be activated with 48V .

Unfortunately , In Egypt ,where I'm located , There is neither EZGO supplier nor technicians that have an experience in EZGO.

So I had to wait for more than 2 weeks until the shipment of a new solenoid online .

So I want your opinions in these solution scenarios :

First: Use CLUB CAR 48 volt solenoid which I think it could be available here.

Second: Use a 36v voltage regulator on the (+) solenoid input . I know that the (-) solenoid input is the PWM controlled pin by the controller that is in my case ( 0V ) . (Am I right?)

Third : I know a technician that has 1311 curtis hand held , But It will be available next week . Also , I checked the manual of this handheld . And I didn't find anything about these PWM settings. So I'm not optimistic of this solution.
Here is the manual I saw : http://www.thunderstruck-ev.com/Manu...UAL%20revC.pdf

Fourth : I tried a year ago to access CAN BUS using a micro controller or a CAN device . Here is the topic I posted before: EZ-GO 2008 RXV openCAN not sending info

I don't know if Curtis controller has a better way to communicate with the CANopen protocol. If anyone can help.

The Curtis controllers used for the RXV do not support the CAN Bus like the Danaher controllers did. The Curtis controllers for the 2Five does support the Can Bus, and it is wired to the Run plug socket, just like on the Danaher RXV.

I know you can access the PWM values on an OEM handset, ie 1311-4401 or 1313-4401. I'll give you the menu structure of the 1313-4401 because I do not have a 1311-XX01 to guide you with.

Connect the handset using the E-Z-GO to Curtis adapter connected to the Curtis handset. Power on the RXV in Neutral and wait for the handset to power on and display the menu screen. Use the arrows to highlight Parameters and press the top right button to Select it. Arrow down to Drivers and hit the right arrow to dial down one level. It should land on Main... Press the right arrow to dial down into the Main options. On a 1206AC-52XX controller set for a 48V Solenoid, you should see...

Main Source 1
Main Pull In 100%
Main Holding 100%
Main Battery Voltage Compe.. Off
Main Checks Enable On

For a 36V Solenoid, arrow down once to select Main Pull In and press the right arrow to dial down...
Use the + or - buttons to adjust the value up or down until you get to 75%. Press the left arrow button to dial up one level, press the down arrow to select Main Holding, and press the right arrow to dial down. Press the + or - buttons to adjust the value to 60%. Press left arrow once, the down arrow once, the right arrow once. Press the + or - once to change Off to On in the Main Battery Voltage Compensated screen. Press the left arrow button repeatedly to dial all the way back out to the top menu. Turn off the key, the handset screen should shut off. Count 5 seconds, then turn the key back on. Repeat the above instructions and just go look to be sure that the values were changed to...

Main Source 1
Main Pull In 75%
Main Holdin 60%
Main Battery Voltage Compe.. On
Main Checks Enable On

If it matches, you're all set to operate a 36V Solenoid.

If you can't get the handset, you can build your own programming interface. Read this thread...
