What is make and model? Is this Yamaha Gold cart, G16 from earlier ? What is the output from the generator to the regulator? Has to be above 14 volts DC, or the regulator will not have enough voltage to send to the battery terminal.

Customer reply replied 1 year ago
the cart is a G 16 model
Technician: Curtis B., Technician replied 1 year ago

Check the output of the generator, with engine running at half throttle, you will need to raise the rear wheels so you can check it. If generator is putting out at least 14 volts, the regulator should have output of 14 volts. If not, replace the regulator.

Customer reply replied 1 year ago
can you suggest i try something else
Technician: Curtis B., Technician replied 1 year ago

It is normal for the voltage to drop off when battery is fully charged. Does the battery stay charged or does it get so low it will not crank?

the battery goes so low it will not crank.
Technician: Curtis B., Technician replied 1 year ago

I would replace the regulator, it has to cut in and out for the battery to be charged.

sometimes i can go 4 or 5 rounds of golf before battery goes dead do you still think its the regulator.
Technician: Curtis B., Technician replied 1 year ago

With generator already replaced , yes bad regulator. They stick and do not let the current flow to the battery.

Customer reply replied 1 year ago
is there any way to test the regulator before i order a new one i think they cost about $80.00
Technician: Curtis B., Technician replied 1 year ago

You can test the input from the generator,with a voltmeter, and the output voltage. If generator is putting out more than battery voltage, and it is not getting to the battery, the regulator is not working.

I replaced the voltage regulator and the same problem is there the battery lasts for so long then is dead when gas peddle
is pressed when battery low cart will not start and amp gage goes to hard discharge could there be a short somewhere.
Technician: Curtis B., Technician replied 1 year ago

Yes, can be a short, or key can not be shutting everything off. If you turn key off and remove the negative cable, and touch it to the battery do you get sparking? Should be no sparking. If it sparks, something is on or drawing current.

Customer reply replied 1 year ago
I tried your suggestion to check for a short there was no spark at the battery post looks like I will have to take the cart to
the yamaha dealier for service unless you can come up with else.
Technician: Curtis B., Technician replied 1 year ago

This is new battery? New generator and new regulator. Dos the battery show more than battery volts when the cart is running?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
the volts show normal at times then it will show discharge it seems to run better when cart is cold also generator gets hot to touch.
Technician: Curtis B., Technician replied 1 year ago

Are you looking at voltmeter in dash or a test meter? the generator is going to get hot to the touch. It will get at least as hot as the engine. The voltage regulator should turn on and off, charging battery when voltage drops below settings. It will not stay steady.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
I don,t know what to try next I think I will take to the yamaha dealier.
Technician: Curtis B., Technician replied 1 year ago

Is this a new battery? I see no mention of you replacing the battery.??

I am going to take my cart to the dealier in the next 2 or 3 days i know it my cost me 2 or 3 hundered
but what can i do sorry you were unable to find the problem..
Technician: Curtis B., Technician replied 1 year ago

Did you ever try polarizing the generator?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
no I don,t think so.
Technician: Curtis B., Technician replied 1 year ago

To polarize an "A Circuit" system, connect the FIELD, ARMATURE, and BATTERY leads to the regulator. Connect the battery. Then, momentarily connect a jumper wire between the ARMATURE terminal and the BATTERY terminal at the regulator.
