03:35 Incorrect: Sensor resistance does NOT go up as pressure goes up. Sensor resistance goes DOWN as pressure goes up. As this resistance goes down, it allows more current to flow through the pressure gauge. This increase in current causes the needle deflection to indicate a higher pressure. 06:23 Incorrect: Zero resistance is NOT an "Open"; zero resistance is a SHORT, which provides maximum current flow. When you see zero at the 20KΩ scale, you have your scale set too high to see the actual resistance. You should turn the scale down to find out what the resistance really is.
@American-OutdoorsNet7 ай бұрын
The 78-87 trucks used sending units designed with a positive pressure coefficient, meaning the sender's resistance is directly related to pressure. So in this case the video is correct. As pressure increases, so does the resistance.

thank, you Chad for you're helpful video. I've. got a 1987, chevy surburban R20 4x4 350 throttle body 400 trans. my problem is I notice every time I check the oil every time before starting I would always be a quart low or a half a quart low I took notice of the right back side of the engine was wet and oily then I looked under the truck and notice was a mess of oil all over the bottom of the oil pan all over the starter and on the exhaust y pipe and all over the bottle of the trans pan. I, thought it was the right back side of the value cover gasket but looking forward in to it I found the problem. correct it was the sending unit that had gone bad so I bought a new one I have not irreplaceable it yet but I'm going to this weekend before driving it again. This sending unit has a single blade hook up. I, was wondering how does the sending goes bad I asume when one goes bad correct it starts leaking I guess it goes bad were it's put togather at. Lol you're dog snoring that's cool. now after I fix the problem I'm going to have to degrees the bottom of the truck and power wash it. no more leaking oil and no more buying and keep adding oil every time. Again Chad thank, you again friend for you're helpful video. ✌
