2003 Sable GS I tried to replace my parking lamp/blinker lamps with LED equivalents. Now, I have very rapid signals (like when you have a burnt bulb). Not a big fan of rapid signals. Is this due to resistance of LED vs filament, ..or a lack there of perhaps??
LEDs draw MUCH less current than incandescent bulbs, and the electronics reads this lower current as a burned out bulb, and trigger the flasher to flash rapidly to let you know there is a problem. You need to put a 5 ohm 20 watt resistor in parallel with the brake/turn filament at each corner to fool the electronics into thinking current drain is normal.
Flasher relay in 03 is part of the SJB/GEM and can not be modded. The G3 Taurus electrical system is 100% different. Nearly everything except the engine in the 03 is computer controlled via the SJB/GEM.
As I stated above, the flasher relay is part of the GEM/SJB. SJB monitors current drawn by the bulbs, and "hyperflashes" if it detects too low a current draw to alert the driver of burned out bulb. The flasher relay in the SJB is just a regular Ford relay.... the flasher timing is computer controlled via a microprocessor in the SJB.
So, NO, you CAN NOT get rid of the hyperflash without using resisters at each LED. The video above refers to the prior generation Taurus/Sable that did not have the microprocessor controlled GEM/SJB. The guy who posted the video apparently is not familiar with the vastly different electrical system in the G4+ Taurus.
I know there are similarities between the gens (almost bought G4 front struts before finding Konis), but wasn't aware that FMC took this away by 03. I put in led front turn signals on a later model Town & Country, which also doesn't have the flasher, so had to install the resistors. I was going to do the rears too but realized it's kinda pointless. For me, it isn't so much the cosmetic aspect of LED's that I find desireable.
One side of the resistor goes to a ground wire running to the bulb.............the other end of resistor goes to + (These connections are at the loom to each blinker lamp in all four corners.)
Resistors are being shipped. Trying to make sure I understand the connections
Was told to use a 5 ohm 20 Watt resistor on each corner lamp. QUESTION: My local Radio Shack store is clearing their shelves as the company faces closure of 100 stores. The only ones they had were 8 ohm 20 Watt. Will these work or is this rather important for 'em to be @ 5 Ohm??
