Alltrax field map for amd7144

[w4rwf]

Wondering if anyone knows the correct field map number from alltrax for an AMD 7144? That's what I asked for and what I got was GGI-4402-V6. Motor is getting extremely hot and smoked yesterday and I have not had that problem till a couple of weeks ago when I put the new Alltrax XCT 500 in. What the motor says on the data plate is GGI-4002.

Tried calling Alltrax today but not open due to the wildfires.

Question for those that probably know, the motor has that sickly sweet smell of motor burn. Continuity test check out fine. I pulled the motor off and several chunks of plastic(?) fell out of it from the armature end. I blew the motor out with an air hose and got all kinds of crap out of it. Dirt, more plastic and normal motor dust.

Should I just reinstall and see if it will run or what should I do with it.

Also, could that field map do that to it if it is the wrong map?

I'm not aware of a GG1-4402 AMD motor. Is this a typo on your part? A GG1-4002 is a recognizable AMD motor. Here is the 7144 map I've been running, along with many other cart owners, for years.

If this is a typo, and you determine what the difference is between V5 and V6, please post it here.

OK, here is where the confusion for me came at. The text file that was sent to me from Alltrax was labeled Fieldcurve_GGI_4402_V6. I just dug out the computer and hooked it up to the alltrax. The field map label on the alltrax controller screen is GGI_4002_V6. I don't know if there is or what is the difference between the V5 and V6.

question about motor temps, i pulled the motor, blew it out real good. found the motor b+ cable had come out from the ring terminal. I re soldered that and crimped it. Hooked everything back up. did about 7 or 8 miles of riding. Highest temp after returning to the house was 220F at the b+ motor connection. That was varied riding speeds from low and slow to about 35 mph but mostly around 25 mph. is that temp to high? i ordered a set of 2 gauge weld wire cables but am really curious if motor should go ahead and be replaced.

Thoughts, opinions please.

Post #21 for internal motor temperature comments.

Without actual testing, it might be wise to assume the internal motor temperature is 100F higher inside compared to outside.

thanks 1sharphook. if internal temp is assumed to be 100F higher then according to post 21 then my temp was not out of place. it was at 160C after a 7 or 8 mile ride running about 25mph for the majority of the ride.

my temps were derived by using an infrared thermometer shooting numerous areas around the external case and the temp at the battery + post was the warmest of all.
