    Oil pressure gauge maxed out

    My oil pressure gauge is maxed out even at idle. I was thinking of substituting the sender with a pot to check the gauge. Does anyone know what the resistance range is for a typical 80 lb pressure sender? Merc 2.5L

When I connect the sender side to ground, I get no movement (this is how I checked my fuel gauge, I do not...

    Fuel Guage Problem

    My fuel gauge shows empty. The tank is nearly full. I took out the sender and measured a fluctuation of approx 26 O to 260 O. After reinstallation it measures 40 O. At the gauge it is also 40 O to ground. The voltage at the Gauge to ground is Source = 12V, From Sender = 7V. Thats 5V across the...

    I am thinking about adding an electronic ignition to an 87 MCM 2.5 liter (GM 4 cylinder). I have seen the kits that replace the points with a pickup. I have also heard that some of these burn up when the key is on and the motor is not running. How do I know which one to buy? Any suggestions or...
