Blown Motor?

[robertbritt]

I've been playing with a 2004 TXT. 10 months ago I put more of a load on it than it should have been pulling. I thought I had smoked the controller, but the cart was still operational. Over the months I have used it regularly and noticed a smell when crawling at slow speeds. I figured it was the controller and knew it would eventually go. Last week I thought it did. I had an Altrax 400 sitting around and put it on. I still don't have any movement forward or reverse....have I blown my motor? Thanks for any input.

Sounds like you might have a series cart with the f&r switch by your leg. If so you are probably smelling the f&r switch. There are heavy duty switches available.

That is true. I thought that, but figured since I had mobility it was more the motor the culprit. Thanks so much.

If it's a series motor, you can put it on jack-stands, and connect 12 volts across one rotor and one stator, with the remaining rotor and stator connected - sorry, I can't remember the letter designations, but you get the point - one letter and another letter in series and 12 volts across the remaining two. On a series motor, you can't connect it wrong as far as polarity - it just changes the rotational direction. I've never done this, but I wouldn't let it spin too fast. It either works or it doesn't.

The FNR can overheat and the contacts will sink into the plastic, until one set of contacts no longer "contacts".

I have been tempted to do that with a motor in the past Yurtle. That is a quick down & dirty way to see if the motor is blown. Thanks.
