LED dash lights, parasitic draw?

[xsaylr]

Recently replaced dash bulbs w LEDs, then over the next few days realized there's a parasitic draw. Found a guide that had me connect a multimeter between the negative cable & negative terminal, then pull fuses n watch for a big milliamp drop. Got 1 when pulling the instrument panel fuse, so now I'm wondering if the LEDs are the culprit. Anyone else seen this happen on these trucks? 97 XLT

That's strange. I would not expect a parasitic draw just from replacing instrument panel lights with LEDs. The circuit should be dead when the key is turned off and removed.

I think, in 97, you have a GEM module and possibly a "battery saver" timer and relay circuit. That can make the parasitic draw test a bit more complicated. When you did the test, were all doors shut and key removed from ignition?

No key but the door was open. Forgot to tape the door chime button closed. The milliamps are at 25, and the test suggests that 20-50 mA is normal, so it appears to be in spec. Maybe that's what the issue was
