Yamaha G19 Not Moving

[equiprepairsv]

Hello. I have a G19 in my shop. After replacing a well corroded solinoid, the unit will sound like it is engaging then will shudder slightly then trip off. Is this a bad motor, bad computer or something else?

Welcome to the forum.

Start with checking that ALL the cable connections are clean and tight. Also what is your battery pack voltage and individual battery voltages?

I have gone through all connections and cleaned then. All the batteries are new and read 6.2-6.8V. The A1 - F1 leads read 51 V, same w/A2 - F2

Hi, I am haveing the same problem. The cart will start like it wants to run but shuts off before it can even move. I have checked all of the wiring and it is all good. I have 6 good batteries with a total voltage of 50.4 volts. It all happened after I replaced the solenoid. The throttle has a 0-5k varible resistor. I checked it and it starts at about 4.7K and all the way down is about 500 ohms. To me, that is good. Is there some sort of sensor installed that I dont know about? the box under the floor seems to be a little bent.... I know that I should hear the solenoid click when I energize the solenoid but it makes no noise at all. I manually tested the new solenoid and it energized. it made the clicking sound and shorted across the post. It is starting to sound like the controller is bad to me. I hope someone can give me some advice on what else to look for. It is a G19E. Thanks in advance for any help!

Its before the solenoid somewhere. The solenoid should be clicking in, so its either a bad solenoid, wired wrong, or its somewhere in the wiring before the solenoid. I'm not a yamaha man so I couldn't help you out with what it could be before the solenoid.

 

[Mr. Lonely]

in looking at the wiring diagram, the only thing before the solenoid is the controller. that is on the ground side anyway. The solenoid should energize when one steps on the acellorator. the micro switch is good. I can manually ground the solenoid and the cart runs fine. If there was a DPDT switch that would fit the micro switch under the accelorator, I would install it and run a seporate ground. Has anyone ever had a problem like this??????

Hi, I'm new. I found this forum cause I am having this same issue. 97 G19E. Even on full charge. Hit the pedal and it lunges, then shuts off.

No mechanics around here. Dont know what to do.

Mr. Loony you said (I can manually ground the solenoid and the cart runs fine.)

You have a bad solenoid if you ground it and your cart runs.

Replace your solenoid that is your problem.

Glad to Help

thanks. I'll put on a new one. It's got corrosion all over it anyway. That cant be good.
