    3.0L Mercruiser TKS turn key start no ground

    It's an "active" ground it appears........Meaning something (a switch/sensor) completes the ground when active. e.g., a one wire oil pressure sender after the engine starts AND it reaches pressure(say 5 psi), closes a internal switch that completes a ground connection through the body of the...

    Overvoltage error on Kohler Generator

    So it appears the design uses a particular dedicated winding off the stator for a feedback(control) voltage to the VR and in-turn, the VR uses this feedback voltage to control rotor current, the amount of rotor current then determines the magnetic field strength of the rotor, which then...

    Battery Switch question

    Curious.....Why have the pump/s on the battery that being the sacrificial lamb w/could be most likely to be killed? e.g, the stupid dog left the audio/sound system and/or cockpit lights on and killed batt #2 flat......No pumps now? Ya fire up the motor on safe batt #1 to of course get power to...

    Switches

    So yes, the cig lighter socket and acc's are two different circuits, the acc's switch is probably not wired to anything, mine wasn't either........... Now you have come come up with something, right? Mine was handy dandy used for on/off control of a 200A SSR that energizes 4 twist-lock outlets...

    Mercruiser 3.0 hot coil

    I don't think the problem(over heating) is being caused on the secondary side (plugs, wires etc)think you're chasing ghosts there!.........The heat is probably being created on the primary side of the coil because you've and/or a PO have modified things beyond the stock setup and the coil's...

    Can electrical power be pulled from a 25hp Merc outboard?

    Agreed, solder makes for a rigid mend and if flexed will break, butt splices would work as well however considering the solder joints here are more or less mid wire/down some distance from the replacement connectors, these are pigtails, no soldering is being done at the housed connectors and/or...

    Can electrical power be pulled from a 25hp Merc outboard?

    Nah, just try not to buy anything "Genuine Merc" and it becomes much more affordable. At Merc, they evidently sprinkle magic dust in their parts for the extra high cost. It's actually re-branded Chinese stuff with some shelf dust, but we let them think we don't know otherwise....... So, your...

    Quality Bullet Connectors

    Use 4 flats tons of times, work well and not that I'm pushing Dorman for any picticular reason but...........Choices choices are always nice https://www.amazon.com/Dorman-91443-Electrical-Pigtail/dp/B005GN0WOA https://www.amazon.com/Dorman-Conduct-Tite-91442-Auto-Part/dp/B004IYYFI2

    Quality Bullet Connectors

    Not "Marine" per se and Deutsch probably bit higher quality per similar cost........I found the Dorman's (both single and dual) on shelf at Autozone and well as Amazon.......... https://www.amazon.com/gp/product/B005GN0WD6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

    Quality Bullet Connectors

    Don't think there is one..........None that I ever found over like ??? (data sheet) or 3M or Molex (data sheet) in that form factor anyway, just found that most Chinese GB made stuff got really really cheap and tried to stay away from it. FWIW, I switched over to Dorman (some spec's)to replace...

    Audio Warning system disable with Key on engine off for Radio?

    I wouldn't recommend adding a switch to shut off the alarm, I'd just wire the radio to work always unless the main battery switch is off...........Does the key position not have an accessories position? Just off and on and start? Assuming not.......you could always get a ig. switch that does...

    Alternator failures

    I assume you have a clamp-on current meter or inline amp gauge with the battery? While running those current readings sound a bit low somehow, esp right after starting up, I'd think, the charge current would jump higher then 3 amps.......... Also, to re-fry an alternator, normally it would...

    Can electrical power be pulled from a 25hp Merc outboard?

    @Crazy_Pilot D.B. makes a good point, is Dads fishing stop and go bass type fishing? What type of runtime while on water are we talking? I'm 99% trolling/motor running these days seems so my perspective is more in that area.

    Can electrical power be pulled from a 25hp Merc outboard?

    Actually, if your alternator is able to provide 2 amps @ 1000RPM or greater for example, which then is of course more current then the example load is consuming (0.75 amp), then any excess current will be made available for charging the battery, this is in perpetuity. This is the case because...

    Can electrical power be pulled from a 25hp Merc outboard?

    My Honda 9.9HP w 12A alt (rated @ 3K) at a whooping trolling speed 1-2MPH (guessing 1000 RPM) puts out around 2-3 amps............Would/DOES run a 0.75A FF easily and leaves any AH battery topped off indefinitely. Guessing a MERC 25HP would be close/similar

    Can electrical power be pulled from a 25hp Merc outboard?

    Does your motor on this side look anything like the same side of the motor below? Three yellow wires leading into vertical finned rec/reg? Red wire coming out of rec/reg with a inline fuse? Can you snap a pic of this side of your motor?
