What controller is it ?
Is this an old or new problem

joesam

Is it possible he is buying eBay (low voltage / cheaperino) sensors and is burning them up?

miker

the controller is a stock curtis 1510-5201 and the sensors come from redhawk, the cart is a stocker with a rear seat, she has had this cart for a while, ran great now this

jjance

Have you ever tried a new magnet. For my info. Does a speed sensor come with a new magnet.

Sergio

A welded solenoid contact would have the same symptom.

If the cart passes the speed sensor "push test", make sure the solenoid is OK.

miker

that's just it ,it does not pass the push test

Sergio

Since You have already replaced the controller and assuming You have a magnet under the sensor, perhaps it is just a harness issue on the sensor wires.

If You disconnect the 3-pin plug from the speed sensor, with the Tow/Run switch on "Run", You should get 15v between the black and Red wires at the 3-pin connector.

You should also get 5v between black and green wires.

If You do, You can test the output of the sensor "Green" wire by lifting one wheel and turning it by hand.

With the 3-pin plug connected and a wire piercing probe on the Green wire, the voltage will go from 0 to 5v - 24 times on a full wheel revolution.

so Sergio you were right I pulled the wire out just to find a stinking mouse ate through the black wire,spliced it and the cart runs fine . this is the best site thanks to all of you

Sergio has been a blessing here for quite a while - but who knew he was a mouse detective, too???
