I'm trouble shooting my tail light issues on my 1994 st. So my rear tail light flashers (the 194/T10 bulbs not the 1157s) are giving me ~47mV then ~65mV then ~78mV every 3 flashes, In that order. I assume they should be between 12-14v. Please correct me if I'm wrong on that. Also if those are part of the dome light circuit, please let me know. (I don't have a spare 10Amp fuse since I blew it trying to wire some extra LEDs and forgetting to put string tubing over the connection, "testing" it, then bam blown fuse because I'm dumb.

If anyone could verify for me that those should be giving 12-14v, before ripping apart my interior to figure out why I'm not getting that, (I might just cut the wires and steal some current from the 1157 flashers since I swapped them to LEDS.

Wow Noah, Good question, voltages sound really weird, like the meter is on the wrong range, test leads are bad, not implying anything, just a ton of years measuring voltages. Without knowing what the symptoms are that you're experiencing, quickest check would be to put all the 1157's back in, and see if that fixes the problem. I'm not sure about the domelight fuse, I'll have to look in my manual for my old '90 ST -since departed I don't know where you're measuring the volts at but, I would expect to see 12v on one leg/pin to Frame ground (any good sheet metal close by(not the trunk lid) scratched down to bare metal. And 0V to Frame ground on the other leg/pin. Measuring across the two legs/pins with the LED in the socket could give really strange readings due to the circuitry inside the assembly. (LED could have a lot more stuff that just a "current limiting resistor" wired in series with it. Hope this helps, TerryE

Noah, checked my BGB, DOME light fuse is for that, plus courtesy door lights, luggage compartment light, etc.
TAIL fuse is for rear flashers and marker lights. TerryE

Thanks Terry, much appreciated, haven't had time to work on electrical work on my car since I'm doing ALL the body work and priming before i get it painted (i may end up painting it myself in my schools paint booth since I've got some skills with painting, but not much )

good to know i don't have to cut the wires! haha

Gotta hunt down that short in my dome light circuit so i can reclaim those flashers!
