Need tips for testing generator 2014 presidente
howdy,
Generator quit charging, verified with a volt meter. Vehicle runs fine if the battery has juice. Does anyone have a diagram for this year? Some testing tips would be fine too. I suspect the wiring is damaged due to other things I've found from the previous "mechanic" like slicing wire insulation and taping an extra wire to them 😳 But this generator has at least 5 wires going to it. I want to figure out if it's the generator, regulator, or wiring. |

Re: Need tips for testing generator 2014 presidente
if I ground DF I get no increase (11.9v) until I hit the rev limiter and it jumps to 16-17 volts with a slight high pitched whine the whole time

That sounds like regulator to me

Re: Need tips for testing generator 2014 presidente
I put a new generator in this, I'm not convinced it's charging. Customer sourced the part and did not get a regulator as I recommended.
I have A1 jumped to F1. F2 Has the white wire to the solenoid NO terminal. A2 has the black wire which goes to battery ground. The white wire is factory spliced into the red wire to the regulator. 0 volts when off, only 2.7v when running. All connections are tight and clean. Something seems off to me, never see anything above battery voltage at the battery when running. |

Regulator is the most common no charge issue

The Yellow wire from the regulator should go to the small DF terminal on the SG. This is the field current wire to control voltage output. If you ground the DF terminal to case/chassis and run the engine to full rpm you should see voltage increase to over 15v output. This would show the SG is good, and the regulator is either wired incorrectly, has a bad connection to + or -, or the regulator is bad. |

Re: Need tips for testing generator 2014 presidente
Ok so this time I tried something different.
In order to eliminate the solenoid as the issue I ran it with everything hooked up as I found it. No charge. I hooked the NO white straight to battery, starter spins, pressed the pedal and it fires up, no charge. I disconnect DF terminal, hook up a cable to ground, touch white NO straight to positive, i get unregulated voltage increase over 15v. Reconnect NO white to the NO terminal of the solenoid, leave the ground to the DF, I get a bunch of whine from the generator when I press the pedal and it runs but no charge. Wtf |

Re: Need tips for testing generator 2014 presidente
should the regulator be fed from the NO terminal or constant power or switched ignition? Right now it's tapped to NO?
Also the solenoid doesn't have any labels on it. The small terminals have an orange and a blue wire on them, not sure if it matters but could it be installed backwards? |

Re: Need tips for testing generator 2014 presidente
Regulator gets power when the solenoid closes. The Red for the regulator should go to the same large post as the white cable for the SG. This is so the regulator is only powered while the cart is running.
If you ground the DF terminal and get no increase in voltage, the SG is at fault and will need to be tested further. Most likely the brushes are worn out or stuck. Those are inexpensive to fix, but it will need to be taken apart to verify. The rubber covers on the end can be removed for inspection of the brushes. |

Re: Need tips for testing generator 2014 presidente
Ive never seen brushes be the culprit for a non charging starter. bad field for me has been the culprit 100 percent of the time.
