    Wiring a kill switch to 85h chrysler magnapower

    No The kill switch does the same thing as the key switch. To start the motor the key removes the ground from the magneto. To stop the motor the key grounds the magneto. Place the kill switch across the same 2 contacts of the key switch (2 mag terminals)

    Thermostat Housing Rebuild

    Thanks Personally I wouldn't use any adhesive on anything. Only place I might use is the paper gasket but that would only be used if the surfaces were not smooth

    Alarms

    I'm not a expert on OB, but all alarms work off a ground. Look for a Tan/Blue stripe wire. This wire applies a ground which turns the alarm on. Disconnecting the connection will stop alarm unless the wire itself is chuffed and grounding

    Alarms

    Might just be one of the switches bent bad, happens quite often. With it running pull the lead off to see if alarm stops, or pull the switches and test them

    90EFI mercury model 1F904531D S/N 2B185185. Changed the low pressure fuel pump in the FSM. Will not fire off, it’s getting fuel.

    Check connections on the injectors. Need to know if something is keeping them turned ON The ECM fires injectors with a ground being switched. With key ON and motor not cranking should see 12V on both pins. If 0V is seen on one side this means a ground is applied and keeping it turned ON A...

    Mercruiser 4.3 injection without any ignition

    Your slave solenoid is bad Having less then 5V on the Gray to Blk/Pink means one of the sensors is pulling to much current or the ECM has an issue. With key ON, disconnect the CPS and see if 5V comes up. If it doesn't reconnect the CPS and one by one disconnect the seawater pressure, oil...

    Which States/Provinces Enforce Registration Numbers Requirements

    Guess I should have phrased the question better, as in which states don't enforce the 3 inch block letters. All good just the same

    90EFI mercury model 1F904531D S/N 2B185185. Changed the low pressure fuel pump in the FSM. Will not fire off, it’s getting fuel.

    Something isn't adding up for the parts list. Post list S/N is 2B185185 and when it is used it shows the diagram shown in post 1, but the hose going in at the bottom of the FSM comes from supply. This hose should not go to anything that connects it to the motor where it would come out the...

    Seeing fuel out the exhaust would tell me there is to much pressure or the injectors are stuck open. Don't know what the pressure should be

    Mercruiser 4.3 injection without any ignition

    The slave relay may be clicking but it's most likely not making good contact inside, so it's not passing enough current to energize the starter. Turn key ON and then use something to go across the top contacts, this will energize the starter. If starter does not energize when contacts are...
