87 cc wont go solenoids dont click
I have a modified 87 cc. im running 5 12volt batterys. a friend was driving it the other day & said he backed out of the garage and it wouldnt go forward. So i put it on jack stands checked the batterys they are all good checked my wiring its all ok when i checked the voltage at the main solenoid it read 0 untill i put it in reverse it then read 37+ volts but none of the solenoids click. No clue what the prob is it is really frustrating me. I also checked the small posts on the solenoids witth the negative hooked to #5 battery negative touched positive to small post voltage was normal 37+ volts then hooked positive lead of voltmeter to positive #1 batt and touched negative to other small post on solenoid and it was only 24volts?

Re: 87 cc wont go solenoids dont click
Let me confirm what you posted, as a stock 1987 CC came as 36 volts with a silver or white speed pedal control box with red ends and 5 micro swiches inside, 5 solenoids and 4 large coil resistors? Any voltage above 36 volts with resistors and without proper voltage solenoids will destroy itself fast?
#1 You are running on 5-12volt batterys ( 6 fill holes on each batterys ) which if in series is 70 volts is this correct? #2 What is pack voltage across all batterys ( from ground end to plus end is pack voltage ) 36-48-70-??? #3 Are you running this cart with 5 solenoids and 4 large coil resistors correct?? #4 Is cart using white or silver pedal speed control box with red ends and 5 micros inside is this correct? #5 Can you take some pictures of pedal speed control, solenoids,large coil resistors and F&R switch so we can have some idea of what you have? Often we find that old a cart has been messed with to the point of having many mixed year parts or some hokey made controlling that does damage to motor and all controls. |

Re: 87 cc wont go solenoids dont click
Yes 5 12 volt batterys that equal 60 volts
white speed control box with red end caps Voltage across battery pack is 62volts. I have 2 sets of 5 solenoids(equaling 10) with speed resistors on each set to split the voltage between the two sets of solenoids. i built this cart myself and have had it this way for almost three years. I have burned up some solenoids and wiring in the begining trying to figure out how to wire it correctly to handle the voltage but once i figured it out havent had a problem since that was almost three now. Other than your obvious replacing twelve volt batterys because they dont hold up as well as 6 volt. I will post what pics i have but not sure how to post them other than to my profile. I will get more pics up asap. Hope this helps. |

Re: 87 cc wont go solenoids dont click
Thanks for the clarification as my old brain said 70v when it is really 60v for some reason? I assume you have one pedal speed micro control set up to turn on both banks of 5 solenoids and 4 resistors in sequence as pedal is depressed, and if so what voltage are you running to the pedal control micros and solenoid small terminals?
On your F&R control are you using stock 36 volt unit with a single micro on back for neutral, and have you upgraded to a heavy duty set of contacts? I would love to see a wiring diagram of how your final build was done. |

Re: 87 cc wont go solenoids dont click
Yes im running 36volts to the one pedal speed controller micros and the small terminals on the solenoids. thtas the weird part tho when i test those with my voltmeter i hooked the negative of voltmeter to neg.#6 batt (#5 ill call it 6 just to make it easy lol) and touch the positive to the small terminal on the solenoid i get 36 volts. okoh reverse that & hook positive to #1 battery and touch neg. to other small terminal i get 24volts?
No i havent upgraded to anything heavy duty yet other than wiring. |

Re: 87 cc wont go solenoids dont click
When you hook digital meter postive to battery #1 and negative to the other small terminal on solenoid you are "including the windings inside solenoid with power to close contacts" so you would see a drop in voltage. The other way around you are only checking voltage to solenoid without coil windings so its 36 volts.
I wonder by having 36 volts going to one micro and then a pair of solenoids you will be pulling voltage down pretty low as you will always have 4 solenoids closed at a time? ( once pedal is pressed you will have 2 main power solenoids and 2 speed selection solenoids all at once? ) |

Re: 87 cc wont go solenoids dont click
i uploaded pics of my solenoids and center council & f/r switch to my profile if that helps. i have more pics just let me know what u need to c.
