Switched on/off power
We are installing the eco battery voltage reducer in a 2015 ydrex6 AC, looking for a 48 volt switched power source. I don't want to embarrass myself but so far it seems to be the large terminal on the solenoid. Any help, suggestions greatly appreciated. Thanks.

Re: Switched on/off power
So if I am looking at the right diagram for the right converter it shows an orange wire can be run to the key switch to use as a trigger to turn on and off the reducer.

just under 5 volts not pack B+ voltage. Will 5 volts activate the converter? |

Re: Switched on/off power
You may have to add a relay to switch the power to the converter if the key switch isn't at 48V. I don't know anything about the newer Yamaha drives. My two are 2009 and 2012 and they have 48V on the key switch.

Re: Switched on/off power
Thank you rstacy, Can I activate a relay switch by connecting to switch wires?
Any suggestions where to grab switched pack voltage other than main cart relay? |

Re: Switched on/off power
I don't know what voltage your relay is looking for but please careful when attaching a relay to the 5-volt line. Be sure to use a diode to prevent damage to the controller. The diode will absorb the energy stored in the relay coil when you shut the current off.
