Alltrax XCT Update 2/15/2018

scottyb · 02-15-2018, 12:01 PM

The issue is the chance of this occurring:

While regening down a hill if the user shuts off the key, or the key loses power for some reason the controller will go into freewheel mode, it will also turn the motor into a small generator and build the pack voltage up over the Over Voltage limitations of the controller. So once you finally come to a halt the car twill no longer start until the total voltage has sagged back down. (This issue can also happen on club cars, which we just found out a day or two ago, so all of the CC IQ schematics will be getting re-updated to show that regen diode again.)

Maybe they should check with BGW next time

I think I will wait until I have a reason to work under the cart again, perhaps a new motor

before I add that Regen diode

If had installed your controller like I did you would not need to get under the cart to install it.

I can see that now

This is an interesting turn of events. I wonder if the Yamaha is also in need of the diode?

I think the Ezgos are particularly susceptible to this problem since changing direction with the FNR will drop the Solenoid.

That is a lot more likely to happen while still moving (right before stop) than turning the key OFF on Ezgo or any Club Car while still moving.

Sergio, correct me if I’m wrong but didn’t we discover that the AllTrax has a built in mechanism to prevent damage from rolling regen??? On the XTC models that is. I thought we determined we didn’t need the diode on the solenoid via the information via Alltrax themselves.

Just curious friend.

It appears that Alltrax has changed their mind. I have a couple of them laying around. If you want one let me know. I'll gladly send you one.

It appears that this diagram, revision F dated 042017, shows:

1. The added Regen diode#5

2. The revision to reflect the correct F1 & F2 wire colors...no longer bassackwards.

Thanks for making us aware.

Call Alltrax and inquire if your install requires a regen diode. If they say yes, request they send you one. Call 541-476-3565
I started sending them out with every IQ controller yesterday
