2002 ds lights out

[antique man]

Headlight problem on 2002 DS club car. 48V. It appears that the headlight system
was aftermarket, because the positive line is taken off battery #5 and the negative
wire was attached to the frame (ugh). Was working ok for many years, but suddenly
No lights. I get 17v on one side of the switch, and 17V on the other when switch activated.
At the front left light..(first stop past the switch) I get 17v on the incoming prong .... and
surprize (to me) 17v on the negative prong. When the bulb holder is reconnected I get
17v on one side of the actual bulb ....and surprize (to me) 17v on the other..
and yet the bulb is not lit....an ohm test on the bulb show bulb OK ....???????.
Any suggestions....other than replace all the wiring and use a volt reducer????

17 volts on either side is zero volts across the lamp so it won't light. You are missing the negative connection somewhere.

thanks for the reply.....I don't quite understand.....How does 17v end up
on both the negative and positive prongs.....is there a "cross-over" somewhere
I did check all wiring and could not see anything that looked abnormal
Obviously I am not an electrician..I appreciate your time

I think I get it now.
If I run a wire (aligater clip) from the "out" side of the lamp to the frame,
would that cause a problem.??...and should the lamp lite up
I would then check the negative wire for a disconnect or replace it from the
negative post of battery #6...

Once again .. thanks for your time

Do you have a high/low beam foot switch? I had the same problem and this was the problem.

Using a voltmeter, find the 2 posts(one negative and one positive) on the battery bank that gives you 16-17volts.

You will be 2 different batteries to get the 16-17 volts. Red wire to positive. Black wire to negative. That should be the fix.

No high beam/low beam switch
Tried routing the negative line to the proper battery post instead of to the
frame ... made no difference
Looks like the negative line is snagged somewhere
Will probably replace the line come springtime
Does the rear movement alarm run off the same 17v system.....?
It has been working sometimes ..and not at others
