Voltage reducer question
I recently installed a 25 amp voltage reducer from Carts Unlimited. It seems to work great but I have a question. There is a "5th" wire that is supposed to be wired to the ignition switch to turn the unit on an off. I have it connected to a constant 36 volt power source to retain my radio memory. I asked ScottyB if the reducer draws power even if it isn't in use and he says it does.
My question is I wondered just how much it draws? Is it enough to be concerned? My usual pattern of use is to use the cart and put it right back on the charger. Anyone have any experience on this? |

Re: Voltage reducer question
OK, just got a reply from ScottyB and he says the reducer should not be left on all the time. Question answered!!

Re: Voltage reducer question
In case anybody is wondering why - leaving the reducer on constantly will greatly reduce the reducers useful life as well as drain the batteries, thus reducing their life.

Re: Voltage reducer question
As a side note there are voltage reducers (like ScottyB 30 amps version) that have a constant low amp 12v output for radios.
You would wire the radio's red wire (switched power) to the 12v switched output and the radio's yellow wire (constant power) to the reducer's constant power output. That will allow you to turn the radio on/off with the key switch while preserving all settings. |

Re: Voltage reducer question
Never tried it, but a battery pack to get 12 volts can probably be wired to keep memory. I thought about these:

Re: Voltage reducer question
I thought about something like this but I think what little draw will be on 2 of the batteries I will just hook it up that way.

Wiring high current diodes or a relay to switch/isolate the power from converter to battery when the radio is off is more complicated than just using the proper converter or getting a radio with "non-volatile" memory for settings. |
