Electrical systems?

[quackaddict1]

is there a website that shows what each of the different electrical parts do on an outboard? Such as rectifier, stators and such?

Also, what voltage should a 28hp motor put out at the terminals?

Re: Electrical systems?

no much, all it is designed to do is maintain the starting battery. not to charge for a trolling motor. although we use to use the same battery for both. 28 is not hard to pull start, if you kill the battery with a trolling motor. then charge as soon as you get home. charging immediately increases the life of the battery.

Do you mean what voltage should be at the battery when it's running? Usually in the 13v range but what I look for it just a higher voltage than the battery at static (non running) which is usually around 12.6v

Re: Electrical systems?

I should have stated, but yes when running, I get a reading of 12.2, which I suspect is the voltage of the battery. Reason I ask is the battery died on the lake the other day. I pull started it but I didn't have to crank on it unusually hard before it died.

12.2v is low. If it's 12.2v running and not running, you've answered your own question! It should be more...

Re: Electrical systems?

Will low voltage cause problems at high RPM? What kind of issues would that create?
