05 Precedent IQ, 48V
Pack Volt.: 51.4V
Curtis 1510 controller, 16-pin Cables clean and tight. Cart has intermittent run issues. Sometimes the solenoid will click and the cart will run, other times not. I've tested Pin 2 on the controller w/ key off and had a range of .3V(pedal up) and 4.5V(pedal down). The info I have states that this Pin should have a range of 0-5V. Does this prove a bad MCOR? If not, what is the correct way to test the MCOR on this cart? |

[QUOTE=Braswell_J;1828153] .... Does this prove a bad MCOR? .... /QUOTE]
The variable resistor part of the MCOR won't stop the solenoid from latching. There is an ON/OFF switch (Foot Pedal depressed) in the MCOR that needs to provide an input to the controller before the solenoid is latched along with a few other inputs. i would check all the inputs for a bad switch/connection/wire to find out why the solenoid is not always getting latched. Inputs needed by an IQ controller with 16 pin connector for it to latch the solenoid by grounding Pin #12 - Blue/White - Solenoid GND. Inputs are B+ : Pin #5 - Light Blue - Charge Interlock (OBC) - (not charging = B+) Pin #6 - Green - Foot switch (MCOR) - pedal down Pin # 9 - Gray - Tow/Run switch - Run Pin #10 - Tan - Key switch - On Pin #16 - Blue - Forward/Reverse switch - Reverse or Pin #8 - Brown - Forward/Reverse switch – Forward |

Re: 05 Precedent IQ, 48V
when the cart is dead ; (charger not connected) immediately check pin 5 at the motor controller for 48+ volts (light blue )
if you don't get 48+ then your on board computer (OBC) had gone bad. if you do get then you need to check other things. mine was intermittent for a long time and first i thought it was a micor problem. but then it died completely and was easy to find. if no voltage you could take a jumper from the plus of the battery pack to the controller (pin 5 ight blue) and just gently hit the gas while in reverse so the cart moves slower and less jump if it turns out to be a bad controller you might want to take my approach (mine is a 2005 precedent) https://www.buggiesgonewild.com/showthread.php?t=173863 |

If the OBC - Charger not connected input is missing the problem may not be the OBC. The +48v input to the OBC may be bad so it may not be able to supply +48v to the controller. The OBC gets +48v from a Red wire spliced to the Pink between the Tow/Run switch and the solenoid. The OBC also gets +48v from the White wire spliced to the Light Green from the Tow/Run switch. Not sure which of those is the one the OBC routes to the controller as I removed my OBC and didn't investigate further. If the Tow/Run switch or wiring/splices/connectins to the OBC are bad it could make it look like the OBC is bad. |

You can check to see if Foot Switch is working with KS off, in tow, pull 16 pin connector, check continuity from Pin 6 to light blue at solenoid. Press pedal to check continuity. I have also seen the magnet on the ADC motor broken into many pieces but all pieces still clinging to the mounting bolt causing intermittent or no running. Even the push test for speed sensor/magnet can get fooled, if magnet is shattered. Don't know why this happens but seen it 4-5 times. In case you don't have wiring diagram, see attached. That's my 2 or 3 cents worth. |
