Hey guys! I have a 1989 ford ranger 2.9 2wd. It ran perfect and everything was working as it should. I couple years ago I hooked up a OBD1 tester just out of curiosity and apparently it fried something? Fusible link? As soon as I plugged in the tester I heard a bunch of beeps and ticks in the engine bay, (Assuming testing all the connections and components) Anyways nothing popped up on the reader, figured I was good to go. Went for a drive and notice all my gauges stopped working at the same time. The truck still fires up and everything, just no warning lights or gauges. I have checked all the fuses (under the dash and in the engine bay). Swapped out the instrument cluster to see if that fixed anything, nothing. Even tried a different ECM, still nothing. Has anyone gone through this before? Can anyone tell me where a fusible link would be regarding this type of issue? Also to add on to the gauges, When I turn the ignition on no gauges move besides the voltage. The needle just flicks once and stays before the 8 volt mark.
