samowens44 welllll how about that! Key on and all flashers work- key off and no flashers work.
Did you put the resistor only on the hot wire? Or one on both the ground and hot going to the black box?
I added a 100 ohm (2 watt) in series with the with the turn signal wire going to the "black box".
I added a 100 ohm, 2 watt in series (inline) on the turn signal input to each black box. I will draw a picture and post up shortly.
All factory wiring to stock remains intact.
To expand a bit on what Sam has posted:
I hope this does not confuse anyone but.....
My added LED strips are "T-tapped" to the existing running and blinker lights.
Electrically, this is an added "parallel" circuit.
Adding anything in parallel drops total resistance of a circuit, thus increasing current.
The lower the resistance of the added parallel circuit, the greater the increase in current.
While I did not measure the impedance (resistance) of these "el cheapo" LED strips, I can assume they are quite low.
As Sam mentioned, when the key is off, battery voltage is slightly lower. Add that additional current caused by the added low impedance LED strip and "boom boom.......out go the lights".
Adding an additional resistor in a parallel circuit increases impedance but actually reduces the load and thus, reduces the current. Making the factory Slingshot circuit happy again.
My light strips are blinking at the same brightness as without the resistors. As Sam also mentioned, LED's are not like incandescent or halogen bulbs. LED's are lit by a chip that provides a constant voltage.
I would be willing to bet that larger value resistors will likely work. How big? That would depend on the minimum input voltage requirements of the LED strip.
Being a firm believer in "if it ain't broke, don't try to fix it"......
I will just thank Sam again for sharing the 100 ohm resistor mod.
It works for me.
