Gauges acting up

[sandcobra164]

My deuce's gauges are acting a little funny right now. This all started when I ran the truck yesterday and left the flashers on. The flasher seems to have died as they just stay on constant now. At the same time, the oil pressure and temp gauges started reading incorrectly. When you turn the turn signal switch now, the oil pressure gauge drops to 0 and the temp to 160. When you turn the turn signal switch off, they start reading normal again. How would turning the turn signal switch effect the oil pressure gauge reading?

Thanks,

Joseph

Problem with the ground wires is my first thought.

My blinkers also quit working ( constant on , but no blink ) after I forgot to turn them off after making a turn . No problem with my other gauges though .

Check the grounds at the flasher box first.

I have to agree with a bad ground somewhere, On DC circuits it will backfeed through something else and drive you nuts. Sometimes you can use a jumper from a known good ground to the part in question.

Might be your flasher controller up on the inside of the engine compartment on the left wheel well area.
