Requests for using power from 604884 DC/DC converter; green & black wires

Textron Label:

Model: RXV FROM ELEC

Date Code: E2812







Recently purchased this EZGO Freedom RXV; has turn signal bulbs but no mechanical switch to operate them. Installed Red Hawk LGT-113 Turn Signal Kit without any issues with the exception that the instructions states remove & re-install the flasher which turns out is no longer included in the kit as the electronics had been moved into the control box. Further inspection of the golfcart reveals the DC/DC converter as shown in the EZGO Electric RXV 48V Parts Manual listed as part number 604884, item #18. There is a multi-pin plug and 2 large terminated wires (Green & Black with white tracer) with the DC/DC converter. I measured something zero ohms from the Black wire to the “negative” terminal of the batteries via last battery in series. The Green wire measures 13.51 only when switched ON using the key. I have not been able to find information if this 13.51 is available for accessories and what the wattage/amperage might be. Any help on this matter would be greatly appreciated.

The 13.51V you're measuring from the Green wire is typically a result of the DC/DC converter stepping down the voltage from the battery pack to a usable 12V for accessories. This is normal and it should absolutely be used for your accessories like lights or the turn signals. The current available will depend on the specific load the converter can handle, but typically, these converters are designed to provide around 12V at around 10-20 amps depending on the specifics. If you're using it for low power accessories like lights you should be fine.

Great! I will be using another DC/DC 12 to 5volt for led lighting with projections of up to 5 amps. I was though hoping for a more detailed technical info as in something watts but thanks just the same.

In terms of wattage assuming the converter is providing around 12V that translates to roughly 120-240 watts depending on the load. At 12V, 10 amps would be 120 watts, while 20 amps would be 240 watts. With a 5A load for your LED lighting setup, you'd be using roughly 60 watts which is well within the capacity of the converter.

Watts (W) = Volts (V) x Amps (A)

So if you know the voltage (V) and the current (amps, A) your device is drawing, just multiply them together to get the power in watts. For example, if your converter is providing 12V and your LED lights draw 5A:

Watts = 12V x 5A = 60W

Thanks. Already had the Led lights & DC 12 to 5 converter, keeping checks on wallet vs what I already have. Found interesting statement during searching to check for label on installed converter, picture attached. Only found input fuse to converter so I will insert fuse on output which will serve 2 purposes. First: existing installed components & second that information will provide remaining available power. I am familiar with voltage x current = watts.
