    1986 MCM 140 wont return to idle speed

    Ohm out the 10 pin connector. The pic below uses DDIS ignition but otherwise should be the same. The helm wiring is a bit different also but the wire colors are the same

    Mercruiser 3.0 engine ignition wiring issues

    Using the connector from the old DDIS unit, attach the Red to the purple, and White to the White/Green. Then disconnect the Black wire from the **** interrupter switch and attach a new wire to it going to Purple

    97 volvo penta 4.3 gl multiple problems

    The key switch. The key should have power on the purple wire when key is turned to ON and keep power on the wire when cranking.

    Ignition Module Bad

    I'm at a loss because of having trouble following. I would say if the TBV (same but better for TB-IV) does not show what the problem is, then need someone smarter then me, which isn't hard to find

    Mercruiser 3.0 early to mid 1980s - Another No Spark

    Its not the coil The purple wire coming from the choke is a resistance wire and feeds the coil when the key is ON (engine running). The yellow/purple should come from the outside terminal on the starter solenoid. This wire supplies a full 12V to the coil when starting Did you replace the...

    Drive Ratio

    Just realized this is a VP, so instead of a slave solenoid, you have an assist relay. Probably easiest way is to remove the relay and jump across pins 30 and 87

    89 3.0 mercruiser starting issues

    Check the slave solenoid. Cross the top 2 contacts and if it cranks over when before it didn't then its either wiring or key issue, or most likely the slave is dying 89-96054T

    Baja NO Trim!! NO Power @ Solenoids

    The 90 amp is on the starter post, and looks like the one on the trim pump. This isn't you motor, just where the fuse is Follow the red wire from the trim pump to the starter and see if there is 12V at that end. It might go the the square block on the starter post (90 amp fuse)

    Spark Plug Wires for 1979 Mercruiser 260 Mallory Ignition

    They look correct, and from the Sierra catalog it also confirms the part number 18-8803 (also agree the -02 appears to be revision). Also matches your serial number range Put the arrow on the wrong line, its the one below it :facepalm: I also checked the boot types in the first pages of the...

    Its the round 10 pin connector on the rear of the motor (in most cases) that connects the motor wiring to the Helm

    Baja NO Trim!! NO Power @ Solenoids

    It can be the 110amp fuse, 90amp fuse on the starter or the 20 amp inline fuse. Suggest checking the 20 fuse first by following the smaller red wire to the inline fuse. The 110 amp fuse is the square block that connects to the starter

    Oil cooler woes

    Making a stab at a possibility, just guessing/spit ball Some have different size bolts. The ones which are used on the flywheel housing that hold spark plug wire holder can be a bit longer on the block size due to the support. Others that are not used for these but still used to hold ground...

    97 volvo penta 4.3 gl multiple problems

    With the motor only starting and not running I don't see it being the fuel pump. Once a carb is full of fuel it should run for a few minutes just idling. Since it starts and immediately dies, this sounds like an electrical problem. The ALT is not the current issue unless its shorted...

    94 mercruiser 350 low idle after thermostat change

    No, the ECM controls IAC and the ECM gets info from the TPS as to where the throttle plate. All must have good connections. Connections from ECM to IAC along with grounds and 12V power

    "chirping" noise coming from outdrive when in gear

    Not hull stringers, I'm saying a stringer drive (the ones with ball gears) like yours The exhaust manifolds you have might be the bat wing type, and if that is true they need to be replaced. Many engines have hydrolocked from them. But then again the pic is not exactly like the batwing (yours...
