g19 solenoid test
My wife's g19 is dead. When I switch the tow/run switch it would only "click" once and a while. When it did "click" it would run. I figured that this might be the solenoid. I wanted to test it so I hooked both of the battery leads together on one post (this should replicate the solenoid closing right?). When I first touched them there was a decent spark but I did it anyway. After connecting them together the cart would not run. What controls the solenoid and was I wrong to connect them together? Also what was clicking when I used the tow/run switch? Thanks for your help.

Re: g19 solenoid test
I did the same thing only i bypassed the switch and everything works now (except the tow feature)

Re: g19 solenoid test
It's really easy to "bench test a solenoid". Weather 12 /36 or 48 volts. There are 2 "small" wire leads and 2 big posts. The 2 small leads, (black ground and red positive) to activate the solenoid. Once activated, you should have continuity thru the 2 large posts. Just because you hear the solonoid "click", doesn't mean you have coninuity thru the large posts to let the current "flow".

Re: g19 solenoid test
If I bypass the solenoid and connect the two battery leads together it should work shouldn't it? Also, why the arc when I touch the wires together, what is drawing power when the cart is not moving? Thirdly, is the solenoid only controlled by the tow/run switch? Thanks

Re: g19 solenoid test
Hello Yamaha Comrades, fello club car'er here. I'm trying to help a friend out with his g19. It won't run and I suspected it was the solenoid, hence the reason I stubled across this thread. Here is what I've tried:
1. Tow/run switch operates. In tow, the back up buzzer doesn't work. In run, it does. 2. Forward reverse switch I assume works because it turns the reverse buzzer on and off 3. I tested the accelerator stop switch, it completes the circuit when test. 4. throttle sensor. gives me the correct readings according to what I found in this section 5. no click from solenoid 6. I have tried bench testing by disconnecting the positive battery lead, then depressed the pedal while reading the small wire voltage...nada 7. I assume the controller is functioning because of the reverse buzzer operability 8. I have not tested the motor. 9. I did place the positive lead from the batt pack to the other pole similar to muskydawg and also experienced a spark. this scared me so I quit. 10. On off switch operates because it turns the batt pack meter on and off when I turn it I am at a loss. Do I order a new solenoid and hope that does it or are there more tests I am not performing. Thanks in advanced for the help Yamaha riders! |

Re: g19 solenoid test
Small spark is totally normal, controller has a bank of capacitors, they are low & need filling, they accept power at a amazing rate to fill. Small spark is totally normal, welding arcs not normal.

Re: g19 solenoid test
Ok, thanks cgtech. I'll bolt the two together then hook the positive up to the batt post and see if I can, once and for all, determine if it is the solenoid.
