Re: DCS solenoid non-activation saga continues
Yes I've verified it. Normally closed. Pedal holds it open until pressed and then it closes and gives continuity. I disconnected the wires from it as well to ensure it was functioning.

Re: DCS solenoid non-activation saga continues
Radioman,
These test were all performed with the precharge resistor installed and only a diode between the small posts. Does this matter? Also the pinout you quoted in your last post was checking from the pin on the controller to the negative post of the battery, not B- on the controller. The post from last night is where I checked all pins against the controller B- and B+ |

Radioman, Yes I agree that seeing voltage on pin 7/6 is showing the solenoid has voltage applied, what I think is still NOT happening is that pin7 is not providing ground through the "Repaired" controller. I believe this because as soon as I manually ground the small post of the solenoid that pin 7 is attached to, the solenoid activates. |

If your multimeter is trustworthy...which I'm starting to doubt, you need to go back to square one and make sure the batteries are installed correctly, and they are correctly hooked to the controller/solenoid. Something very basic isn't adding up here. |

Re: DCS solenoid non-activation saga continues
I'm starting to think pin 6, and the positive small post on the solenoid are not always getting B+. It may have some voltage through resistors and coil windings, but not a solid B+, and the voltage will disappear under any load..
Their B+ needs to pass through the interlock, the tow/maint switch, F/R switch and the key switch. All of those must be working correctly for there to be a true B+ at pin 6. You can bypass all of these for testing purposes by putting a jumper wire from B+ to the positive small solenoid terminal. This may make your results more repeatable. If you are testing with the charger plugged in, the interlock switch won't send B+ to the solenoid. The jumper will solve that. |

This is just not possible. We have a saying in the IT world...GIGO

The B- on the controller is hooked directly to battery B- The diode is installed correctly with banded end toward B+ Battery input. B+ cable Runs from controller side of solenoid to B+ on controller as well as A2 on motor A1 on controller runs to A1 on motor Also verified the multimeter resistance on known good wire off cart as well as battery in a seperate vehicle |
