    Tilt trim solenoids

    With fuses good than guess is you left a wire off The power comes from the battery to a the trim solenoids and to trim switch. The trim switch applies power to the solenoid when needed

    Looks like VP uses power from the key goes straight to coil when cranking and once started it comes from the ALT thru a ballast resistor item 22 So when the key is ON and not running power comes from both

    Over heat alarm

    Welcome To follow up on what Scott mentioned, look and see if the wires are on the correct sensors and have not been miss-wired. This usually won't happen because the sensor connections in most cases are different

    AQ131 Questions (Spark Issues)

    Welcome The ballast resistor is the wire it self and don't think there is anything wrong with your coil. Meters are hit/miss with their accuracy and it's hardly never the coil You should have 2 wires on the plus side of the coil. When cranking it should get full 12V and once started the...

    1990 mercruiser 4.3 no spark

    The sensor is just a switch. Striking the Wht/Grn is doing the same thing as the sensor. This is the reason it says to strike the wire to ground rapidly several times (not just once or twice) So if it sparks doing the wire and not the sensor, that just shouldn't happen Reason to do the coil...

    As you stated, it goes back to the sensor To verify, the spark gap tester is on the coil wire with both Wht/Grn wire and when cranking?

    1990 mercruiser 4.3 no spark

    Just to verify the issues With 12V on Wht/Red wire and striking Wht/Grn wire "rapidly" you have spark and it sparks many times and not just once or twice Rotor rotates and firing order is correct The ignition module does the same thing as striking the Wht/Grn wire rapidly to ground. So if...

    Welcome Is this a new to you boat, or did this just happen reticently? With distributor cap removed, crank the motor and does the rotor rotate Is the ignition module have 2 or 3 wires?

    SmartCraft: Help needed!!

    Most install using a J-box, and the reason is if something goes wrong and you need to scan for codes you only need to remove the dust cap on the box to read. If you don't use a J-box and just use a 10 pin cable from the motor then you need a resistor 10 pin CAN connector and just connect Gauge...
