Hi, I have a 97 ford ranger and the gauge lights and tail lights are not working. but when i hit the brake pedal it lights up. i know the bulb works because its the same bulb thats used for the running lights. Ive looked high and low on the internet and through the trucks fuses but all seems to be good there. No blown fuses, but i recently hooked up a volt meter to see what my DRL (daytime running lights) fuse inside the cab on the drivers side dash panel, and the fuse that controls both these actions is not getting any good voltage (like 0.346). I am not good with electrics but Im trying to learn. Could it be a relay, or is that only if the fuse is blown? And i know a short or bad ground would mean the fuse would be blown right? Lmk any help is greatly appreciated!
Load test your alternator and battery, Check the battery for corrosion and especially a good ground (negative terminal) connection.
