    Mercruiser 3.0 TKI engine crank half time - never starts

    I live in Sweden but not sure it was proper winterized. However its closed cooling system. But what you see is a weird picture due to sunlight and it’s actually oil but it doesnt appear to leak.

    Mercruiser 3.0 TKI engine crank half time - never starts

    This is how it’s all connected. Bottom of picture I cant see because it goes between engine compartment. Only tried meter reading on batteries and they showed 12,4 and 12.64. When I do circuit tracing - do I need to worry about which battery ground pool I connect the mentimeter to when testing...

    Mercruiser 3.0 TKI engine crank half time - never starts

    Yea, checked connections at start motor and battery but looka fine. But I could actually try to disengage the m-acr and isolate on battery ti use the same for both start motor and accessories. Only thing is that is wired strangely with the m-acr.

    Filling coolant reservoir 3.0 TKS?

    Ouch! This was in complete cold condition. Any suggestion what to do? It’s already in water so want to avoid draining it. Just refill up to the top with new coolant liquid and then change everything after season?

    Filling coolant reservoir 3.0 TKS?

    Thanks for the patience 🙏 I think I start to understand. I will open the thermostat on expanion tank to take a look later today but looks like reservoir then may function properly. If expansion tank is full then no need for refill? Dunno about the color though (see pictures) 🤨
