How do i check the amperage on my jd gx335 garden tractor

Hi Stacy:
I'd be suspicious that it's not getting fuel, but considering the age of the machine............ probably time for a methodical maintenance check.
Spark plugs (if gas). condition and check for spark.
Did this only happen once, or if you leave it for a while, will it start again and then die?
You may be able to find a forum of owners of these machines.
Here's a link that may assist.

it could either be a charging system issue ~ check for above 13volts at the battery with engine running at more than 1/2 throttle

or

suspect your battery light is stupid :-)

The safety switches, one or more not closing

you may need to check that your blade engage sensor is working properly, and that the one on the seat is working properly. if not that, then check the ignition fuse connections. they may seem to be connected properly, and still not be seated properly. good luck.

Hi, if it has a fuel shut off solenoid in the bottom of the carby bowl check that it is getting 12 volts with the key in both the start and run positions. If so check that the solenoid is clicking when you turn the key on and off. If not you will need to replace the solenoid. Hope this helps, regards Phil.

Try cleaning the vent hole in the gas cap. I had a similar issue and this worked great. Good luck.

i have the same thing a tractor shop told me thats ok they are slowed dowm for saftey

when you turn the key on to the run positon do you hear a clicking sound coming from the carburator? this tractor is equipped with a fuel shut off solenoid on the carburator if you dont hear the clicking sound solenoid is either not getting 12vdc or it is defective.
