2007-16 Yamaha G29/Drive - 48v Solenoid
Review:
MY CART (0)
Cart Subtotal:
The Yamaha Drive 48v Solenoid is an excellent unit for getting the power where it needs to be. Are you aware of what is actually happening internally to achieve that end? When you hit the pedal on your caddie, the controller sends signals to the two small terminals on the relay. This is at the total voltage of the batteries but only a few amps. When this happens, you will hear a click. That is because the signal that was received from the controller was used to create an electromagnetic field that forced a movable contact to join the two larger terminals. These have your large cables connected to them. Every time you hit the pedal, this happens. You can see why we consider this a high wear item.
This golf cart solenoid is not a difficult part to install by any means. You want to make sure you flip the run and tow switch to the tow position and disconnect the main battery positive and negative. Once you have done that, you have a couple of cables and wires, then you are done. Call Buggiews Unlimited and get one ordered.
I had the same problem you are having , I change all the little stuff first , But after changing the controller my clicking stop and thee intermitten stoppage quit . talk to these guys in support they are very helpful .
I don’t know a lot about Yamaha. The controller does control forward and reverse. I would check the wires from the controller to drive motor it has labels for forward and reverse to make sure they are in the correct locations.
i am not an expert, but the solenoid will only have voltage pass through it when it gets a signal from another source i believe, the small terminals. i would not replace until further investigation. check signal at the pedal. though the solenoid is the cheapest part to replace, good luck.
I'll bet you have a hotspot in that motor so unhook it from the electrical system and jump it directly in the cart and see if it surges like it does when you're driving if it does is that motor you buy past everything else
When my batteries get low mine will do the same thing. After the second click I can switch the ignition switch to the off position and then back on. The cart will then run, Don't know if this helps.
It needs a solenoid
