Re: power wise problems
When you say it comes on fine, does that mean there is the normal 2-5 second delay before the relay energizes after the cable is plugged into the cart?
Does charger have standard PowerWise plug or something different? If different, where is Battery sense wire connected? When you unplug it from the cart and it stays on, what is the voltage between the + & - pins on the output cable? The control board needs 44-46 volts or so for auto shutoff. Do you continue to get a reading on ammeter after it is unplugged from cart? |

The two board setup might have been replaced with a single board upgrade kit, which may or may not have been installed correctly and is now not working correctly. Unless the relay is bypassed or the control board isn't doing what it is supposed to, there should be a few seconds delay before the charger comes on. Then the charger should turn off when the battery voltage reaches 44-46 volts, or after about 12-16 hours when back-up (safety) timer times out. The battery sense lead connects to B- either via the Aux. contact in a PowerWise type plug or hardwired to it in a two wire plug. The charger will not turn on automatically unless the battery sense wire is connected to B-. If I were in your shoes, I'd order the upgrade kit, which comes with instructions, install it from scratch and provide the customer with and properly working automatic charger. |
