Default So your Yami won't turn over

Been seeing alot of posts about carts not turning over/starting. You will need a volt meter! The starting circuit consistes of: battery/battery cables/fuse or fuses/wire harness/key switch/stop switch (at accelerator pedal)/solenoid and starter/generator. On G16's and up there is also a "stop relay". Jack up the cart or put it in neutral. I recommend cleaning the battery posts and cable ends back to clean/brite lead. Put your volt meter on the battery. Try to start the cart, battery voltage should not drop below 10 volts (cart will hesitate to start with low voltage), did you hear the solenoid click? If battery checks ok and you heard a solenoid click bypass the next steps and go to solenoid output test. Take the brake/accelrator acsess panel out, the "stop switch will have 2 wires (brown and red) disconect the brown wire, you should have battery voltage all the time, if not,battery/fuse/wireharness problem. if battery voltage present, reconect and check for battery voltage on the red wire comeing out of the stop switch. You should only have voltage when you "press" the accelrator pedal. Try it several times (you may have a intermitent stop switch). If tests good, the red wire goes to the solenoid (to "energize" it),reconect the red wire, now put your volt meter on the (small) red wire at the solenoid and push the accelerator pedal. You should have battery voltage. Check the voltage at the (small) black wire at the solenoid, you should have battery voltage at all times (if not, bad ground wire). If you have ground (black wire)and 12 volts positive (red wire) when pedal pushed, your solenoid is bad. Test solenoid output (the 2 big posts), you should have battery voltage at the post that the positive battery cable attatches to, put your meter lead on the post that goes to the starter/generator, push the pedal. You should hear the solenoid click and battery voltage should be present. If not bad solenoid, if good the starter/generator should be checked. Remember to check the negative batter cable the the starter for voltage also, there should be battery voltage reading at all times. Hope this helps anyone with a starting problem. Dave
