I will check that out. It should be easy to tell if the wire is saturated with coolant. Thank you

The company i work for has just purchased a 2001 mack ch613. We purchased it in Houston TX and i drove it to our shop in Nebraska. On the way out of town the instrument cluster started dropping all the gauges to zero and then would stay off for awhile. Now it only does that here and there but the electronic malfunction light is on. I have not had it give the blink codes yet. Also on the 1200 mile drive back i fueled up about half way and the truck ran terrible for 200 miles, wouldnt pull hills, 55mph max and you could not here the turbo spool up. I changed the fuel filters and added stabilizer and about 100 miles after that it would run good on and off. It seems to be running good now but i have not drove it any kind of distance since the trip. I am wondering if the light and gauges and sluggishness are related? What do you guys think?
