New Switch boxes on Merc

[bigshrimpin]

I was so proud of myself for finding a deal on surplus UPS AGM batteries this spring. I got 4 super deluxe Northstar NSB100FT(list price was $468 each) brand new never used for $40 each gov. surplus from Big Hog batteries. I thought I was so smart :)

you're still ahead of the prie of new batteries, I don't think they had anythign to do with the ignition, just check the charging system output of your motor, its usually not problem with old school two strokes, just an issue on anything with a high output altenator. Personally, I can't findd a better battery than the Deka 24-M7 no maintance(same thing as the west marine 1000 MCA white battery), I have sold probably 50 of them in the past 5 years, I haven't seen one of them go bad form other than missuse or lack of use

Switch box would be my guess.

Thanks for the replies y'all. I have been out of touch for a while. My mom was in the hospital in Pittsburgh over the holidays, it was cold up there.

I still haven't swapped out switch boxes (chore # 1241524) but thats the next thing I plan to do. It sure acts like half the cylinders just drop out. I've had that happen with (i think) older mercs on work boats, the mechanic called it a power pack then.

As soon as I get those switch boxes on I'll let you know how it went.

BTW I've messed with al sorts of high tech batteries & I always come back to a deep cycle marine, it's the longest lasting & toughest battery.

Chasing old threads to fix this same (or similar) problem & see I didn't finish this thread up. It was the power pack, switched them both been running fine ever since. 7 years!

This time it has half the power it should but there was no intermittent stuff, it just never would run right, from startup. - new problem, new thread.
