Fuse blows between CDI pack , replace fuse but now engine bogs and slowly picks up speed

Replace blown fuse but lost top end

CDI's are not fused, you mean the rectifier/regulator?

 

[bluebear57]

Could be there is one running along both of them , my temp gauge shorted out and after that the engine would not start and I replaced this fuse and it would run except now has very weak top end, dogs out and takes a while to get up to speed, was sure what I messed up, replaced all electrical last year stator chi trigger etc, thanks for looking at my problem

It’s a 89 mariner 150 ,SN OB117411, I’m afraid I might have damaged the top end of the new stator I just put on, completely redid this motor last year, and because of health issues would like to have a idea where to start looking , thanks again for your time

This is the fuse that was blown , and then the motor would not start,replaced fuse, motor would Run great but the top end would bog down but slowly pic up rpm’s and speed Thanks again

that fuse has nothing to do with tha way it runs... you really need an oem manual for it.. way to many reasons as to why its doin' what its doin.. need ta be able ta actually see and hear whatcha trying ta describe.... sorry, jmo.

I know the fuse has nothing to do with how in runs, but I think the power sure that blew the fuse shorted something out Thank you , I think I might have damaged the high in coil on the stator , or maybe the trigger, something was damaged when things shorted out , guess when I can I’ll get my ohm meter out a begin to try and check everything electronical ,thank you for you time and input

Hi. I can’t just remember, but either that fuse holder or the other just forward of it on my 150 merc was intermittently failing. It caused the engine to run poorly and a couple of times, fail to start. I had to cable tie it securely that day, for it to stop its issues.

Thank you I’ll check that out

Disconnect the yellow wires at rectifier and retest

Thank you , hope it only the rectifier, will that cause a loss of top end power? A bad rectifier, thanks again

Thank you for all your help , had some health issues, so I haven’t been able to look at it for a while, but looking today I found where the fuse blew out. The rectifier was melted to so replace rectifier and things seem fine. Thank you very much.
