Help. I am being driven nuts by my jeep. I have a 2001 Jeep Cherokee XJ/ I replaced my turn signal and brake lights with LED bulbs and they flashed way too fast. I then bought a LED flasher unit that is designed for LEDs (EP27-L) since I was told that there is no such thing as a heavy duty flasher to replace the stock one. That cured the flashing speed problem and the lights work fine now. I really like the way the LEDs look.
Now the problem - Today I plugged in my utility trailer and for some reason the left turn signal causes both tail lights to flash. The right turn signal works normally. Brake works ok as does the running lights. The trailer wiring is ok and bulbs are fine. Checked the trailer ground and its ok. Checked the voltages at the connector and when the left turn signal is on there is voltage at both left and right turn connectors. When the right turn signal is on, only the right connector has voltage. I have a factory installed tow package and everything worked fine before the LED conversion. And the question is..... What could cause this and how do I fix it? Any ideas would be appreciated.
