Golf cart charger relay wiring

I have a Lester II Model 14100 Battery charger that I need to replace the relay on,I am not a wiz on electrical wiring. The new relay is not labeled like the old one, so I do not know which wire goes were, the new one is not numbered for the wires as the old one, It just has the same number of wiring slots, one labeled COM and another labeled NO, but nothing on other 2. Need help wiring relay.

You did not tell us what relay you have and there are hundreds or thousands of different types. Including photos of the old and relays will help up tell you how to hook it up. Here are instructions for posting pictures.

The diagram I used is from the link below. I labeled the COM and NO terminals. The other two can be connected in either direction. If it's a DC relay..... the orange would be + and the brown would be - .

Just some additional words of wisdom...... the relay is activated by the battery it's charging. If that battery voltage is too low...... the relay won't activate. That means after you change the relay you'll most likely have the same problem unless the old relay was burned or melted.

To verify charger is good and problem is a dead battery, do the following. With the charger plugged into an outlet and connected to the battery, momentarily jumper the relay's COM and NO terminals.Use an insulated jumper wire and be careful as the wire connected to COM terminal should be at 120 vac potential. The relay should energize and the ammeter should indicate current to battery. If not the charger has a malfunctioning part(s). Schematic shows a fuse assembly. Looks like a fusible link. Check that.
