I recently added extra lighting on front of my low rider.I tapped into low beam of headlight works for awhile then fuse blows. Does anyone know a way around this problem?thanks

 

Too much draw on the circut - especially if ur runing driving or fog lights - need to be on their own circut. There are spares in your fuse box.

 

+ 1;

Here are some wiring diagrams showing how the aux lights should be connected, according to H-D's mounting instructions (=DOT regulations).

In this way the aux lights stay on only with lowbeam(spliced to the yellow wire).

If you want them to work with high beam, splice (6) to the highbeam wire (on my 2003FXD it's the white wire).


If you want them to work independently from high/low beam:
Splice (6) to the runing lights wire (see your manual for the color, on my 2003FXD it's the blue wire) or run the "unterminated wire" (6) (= wire to low beam in Fog Lamp Schematic) in the wiring harness back to the + on the battery or the aux fuse in the fuse box.

You can operate the switch (which comes with the H-D aux lights kit) to activate the coil in the relay which will turn on or off the fog lights/aux lights.

I have connected the passing lights on my FXD2003 in the same way and replaced the stock switch from the kit for the handlebar mounted aux switch kit and the chrome switch cap kit.








Here's a wiring diagram on how to wire aux lights using a relay:



Signal current from switch (86 ==> 85) activates coil; coil activates internal relay switch (30 ==> 87)

30 = + from battery (requires mim 2.5 mm2 wire)

87 = + to lamps (requires mim 2,5 mm2 wire)

86 = + from switch or headlight wire (to activate relay)

85 = ground


Here's an image of the l/h side switch kit on my FXD2003:

 

Good post (as usual) Rene.

I think the operative word here is USE THE RELAY and wire it in as per the instructions. You wont blow fuses that way. If you do, then you pinched a wire and you have a bit of backtracking to find it.
