Relay Needed AFTER the 12V Reducer?
OK, I'm probably mish-mashing several wiring diagrams that either address fuse boxes OR relays, but am I correct that you do not need a relay AFTER a 12V reducer, in that the relay powers the reducer, correct?

Re: Relay Needed AFTER the 12V Reducer?
Why do you want another contact in your circuit?.....What will you use to trigger the coil on your relay?....Make sure any relay is rated for the proper current, and voltage.

Re: Relay Needed AFTER the 12V Reducer?
my reducer only pulls <10mah and the supplier told me yesterday that I don't need to worry about it. The batteries drain faster by sitting than it pulls. So right now I have no reducer and the pack is still at 51.1 volts off charge sitting for a few days.
After the reducer I don't see a need at all. |

If people are worried, put in relay, and tie the coil to the switch...Every time we add to a circuit we add one more place for failer. |

Re: Relay Needed AFTER the 12V Reducer?
There are two reasons to use a relay on the 12v side of a converter (assuming 48v cart):
1) Your voltage reducer does not have a "trigger wire" and You would like to have all of your 12v accessories turned OFF when you turn the key switch OFF.In this case you would use a 48v coil relay wired to the key switch and run the +12v output of the converter through the relay N.O. contacts. |

Is there a more comprehensive wiring diagram that show every inline fuse, representative relays on either side of the reducer and fuse box, and representative toggle switches, main switch, radio and lights ? It's probably lot for one schematic sheet, but these are common combos that are often asked about and might be a candidate for a sticky. It seems I'm having to join up two or more schematics taken from the forum and I don't want to screw it up. |
