    Overcharging?

    It is a brand new lead acid Die Hard 800 marine starting battery. The charging voltage gets up there when underway. I’ll keep an eye on it - I was just so happy to see it not pinned at 15 to 16. At first it was 14.2 to 14.5 and I thought it was still broken but it came down from there when at...

    Overcharging?

    Update- all fixed. Installed the new regulator rectifier and it is charging at 13.2 volts at idle. The tachometer was still not working. Installed a new one from off the shelf at West Marine. It idles at 900 :) took my daughter out on Lake Michigan in Chicago to watch the Thunderbirds air show...

    Overcharging?

    Can you tell me please if charging at 14 volts is okay. Where should it be? The impeller, battery and regulator are brand new and the water flow is good. If 14 is too high, what would you suspect next, to be the cause. Thanks in advance… Steve

    Overcharging?

    This makes good sense. I did replace the impeller, the damage may have already been done from before so I’m glad that I have a new one installed to accompany the new regulator. Is there a good method of testing for proper cooling of the rec/reg? I have not experienced any over heating issues.

    Overcharging?

    The tach is unfortunately still not working. The gage is holding steady at 14 volts, does this sound okay? I’m not really sure what is the acceptable range reading. I will try a new tach next but it is running well. Thoughts? (14 volts at idle on the hose)

    Vics, I installed the new refrigerator/rectifier Sunday.

    Overcharging?

    Thank you! I have the new rectifier and looking forward to pulling the flywheel. The connections are clean, it must have gone bad after 30 years :) from what I’m hearing, the tach not working is a sign of the problem. Fingers crossed because other than this this motor run and looks like new. It...

    Overcharging?

    Thank you! I did recently replace the impeller, could I have created this problem? I don’t recall if it was happening before that, I replaced it because it was old not because it had failed. How does the impeller affect the voltage? Thanks again?

    Overcharging?

    Volts :) Thank you! I replaced the battery with a new Die Hard and used stainless nuts righted up good - same problem. I ordered a new regulator/rectifier and will install. It’s the 89 model that requires the fly wheel to be removed, with the fly wheel off is there anything else that I may want...

    Overcharging?

    Greetings, knowledgeable engineers! I bought a 1989 Johnson GT150 late last summer, it’s on a same year 19’ Bass Cat. I’m not a big fisherman but I love the water - anyway, I rebuilt the carbs and changed the plugs, wires, filter etc. I have it running pretty nice (it had very low hours and...
