'08 Precedent Beeping dash

[Mikeyjohnston]

Batteries check ok, charger won't come on, charger checked with other cart, worked fine. Cart seems dead, won't move at all, no rev beeping or any other sign of normal operation. Initially when pugged into charger, beeping in dash area until flipped to tow mode. That silences the beeping. This is NOT rev beeping. Getting the dash area to beep doesn't happen every time. Mostly when charger is plugged in there is nothing but silence, charger never activates. Any ideas?

The beeping you’re hearing is probably related a safety feature that prevents the cart from moving and alerts you if it detects an unintended movement like the cart starting to roll away on its own. When activated, the system alerts by beeping so the cart doesn't move unexpectedly.

Given that you're experiencing this beeping intermittently and for unknown reasons, we need to figure out why the roll away protection is being triggered. The first step is to check the overall battery voltage, as the charger typically won't activate if the voltage is too low. Use a digital voltmeter to measure the voltage across the entire battery pack, it needs to be within the required range for the charger to kick in. If the voltage is sufficient and the charger still won’t engage, the issue could be elsewhere.

I’ve seen cases where the roll away protection system activated unexpectedly, even when everything seemed fine, and it often turned out to be a bad solenoid. For instance, there was a time when the cart's batteries were load tested and found to be in good condition, yet the cart wouldn’t move. After some investigation, it was discovered that the solenoid was failing intermittently which caused the system to think the cart was in a roll away situation.

However, we don't want to just replace the solenoid and hope for the best, first there are some tests to run. Typically youd start by putting the cart in TOW mode, then label the wires and disconnect it from the cart. Then, use a multimeter to check for continuity across the two large terminals; when the solenoid is off, there should be no continuity. Next, apply proper voltage to the small terminals, this should activate the solenoid and produce a "click", and you should see continuity across the large terminals.

If the solenoid does not click when activated, it means that it's not engaging to connect the battery power to the motor. This could indicate a faulty solenoid, an issue with the activation circuit, or a problem with the power supply to the solenoid. Without the solenoid clicking, the cart won't receive power to the motor, and it won't move. More tests will be needed to figure it out.
