Hey Mudders, can I tap into your experience and wiring expertise for a moment?
‘76 FJ40 mostly stock. Restomod style.
I have converted every bulb to LED except the headlights which are H4 with a relay harness. I am extremely happy with the improved lighting, especially on the dash and cluster.
There is an issue that I need to sort out though. When its raining the turn signal display in the guage cluster misbehaves. The indicators that is selected illuminates appropriately, but the bulb that should be off also lights up and flashes dimly.
My guess is that cracked wires or an exposed harness plug is “bleeding” voltage through the rain wet insulation to the other circuit and since LEDs require such low voltage to illuminate, I am seeing it on the dash. The wrong side exterior turn signals don’t appear to be illuminating when wet, just the dash. Although I haven’t pulled off the lease cover and looked close for dim illumination.
This phenomenon happens with both right and left turns. It resolves once dry.
My plan is, on a dry day, to have the blinker on, and sequentially wet down different areas of the rig until the issue appears.
Have you ever experienced this? And can you point me toward a connection or wear point that might be the likely culprit in this case if intermittent flasher missbehavior?
