48 to 12v converter frustration

churchman · 06-18-2014, 01:26 PM

I bought a light kit for my 2003 DS 48 volt. The converter model number is a
SWTF-4812/18A. The problem is it's a 5 wire system and the systematic is showing stub ends to nowhere as the following:
Large yellow wire output
Black Wire Thick, output ground
Black wire thin input ground
Red White control trigger line
Red wire input (With Fuse)
All this and no shown connection points

Any insight would be help full
Thanks

LOL- They are all pretty much the same, this will give a general picture of what you are about to install.

Looks like you have only negative 12v output, correct?
If yes, then the 12v positive comes from the battery pack main.
You can test this with your meter to be sure before connecting anything 12v.
The switched wire is usually to the key switch - provided your keyswitch is the correct polarity.

You will need a standard DMM (meter) to safely install this one I think.

Black wire thin input ground -48v Input
Red White control trigger line +48v from keyswitch
Red wire input (With Fuse) +48v constant input from pack

It has an unconventional trigger wire color, but the gauge of the wires give away the functionality.

Thank You Sergio! Why Couldn't they they have written it that way

scottyb · 06-18-2014, 05:09 PM

I copied the part of the post that had the wire definitions, run thru a chinese translation then back to english.

This is how it would read if it came in the box:

Quote:

Large +12 v Output yellow wire
Thick black wire, the output of land-12V output
Entry fine ground-48v input Black wire
Red White Line trigger control +48 v selector switch
Check Red wire (fused) +48 v constant input packet
