Hello!
Nice video and Good that you did a bench test,but be careful.
This is OK to check some level of functionality of the solenoid, under a very small load of a light bulb, maybe a few 100 mA?, however it does not really prove that the solenoid is fit for purpose.
Over many cycles over the lifetime of a boat, the main switching contacts arc, get pitted and dirty and can be really in rough shape. I just replaced both solenoids on a hydraulic trim pump with new ones. Even though both solenoids were “clicking and working” on the bench, I measured the resistance across the switching studs and this was anywhere between about 10 ohms and 150 ohms, randomly changing with each test( no not a loose connection)….just shows the nasty condition of the contacts after many years of use. Imagine the heating effect and losses in that contact due to the high resistance accelerating further deterioration.
So whilst I think it’s OK in an emergency to use an old solenoid to get the motor started, it’s really a false economy , when you can fit a brand new one for less than $20, and know that you will have many years of reliable service .👍
Awesome! Totally agree! Plus they are cheap enough nowadays to replace! Thank you again for watching and great information!👍😉
Your channel s great. I wonder if u can make more videos fixing boat
I am I have alot of videos that need to be edited! Thanks for watching!
Having an issue with my just purchased 470 panther 19 inboard 470 starts and runs good when it starts it doesn’t turn over I can hear clicking in the engine Bay Area when it’s cranked to start .Any suggestions it’s random may crank 10 times then the one time it won’t seems to happen more when warmed up any suggestions
Could possibly be a grounding issue or corrosion, check you cables and battery make sure you have nice shiny copper, or do you have points or electronic ignition?
I have 1980 470 Mercruiser and the motor turns over when you hold the key like it is started but as soon as you release the key it does not keep running. I thought it could be the solenoid but looking at the wiring diagram I dont think so. We have replaced the ignition switch. It is like key circuit is broke as soon as the momentary key switch is released. I thought maybe the solenoid was like a latch relay but now I dont believe so. Any thoughts on what it could be?
If you replaced the ignition switch did you reverse the wires by accident?
Well it was actually doing the same thing before we replaced the ignition switch. Found a wiring diagram on line and am thinking it could be the coil or circuit breaker. The starter is a momentary switch so after it is released it is like the electrical connection is broken.
Thanks for the video - if my starter works on my Mercrusier then I don’t need to test the solenoid - correct?
Correct because if you have a bad solenoid your starter motor wouldn't work! Thank you for watching!👍😊
@@WhitehouseFarmVet great what about the breaker red button - how to test that..?
@fredrikfabian9591 that's your main circuit breaker when your boat is running if you press it ,it should cease all operations it should be a 50 amp!
mine click but thats it i will try that to test it i just purchased it / starter
Let me know how you make out and thank you for watching!👍😊
Mine clicked too then I kept holding the key over & it ended up finally turning over. It was the starter & the solenoid went out right after.
Definitely needed to be replaced!
@@WhitehouseFarmVet having too much fun learning on this boat🥰
That's awesome!!!!🥰
