msd
 

I think my msd blew yesterday, we were putting a new starter back in, and I left the batts on:eek:. was told there was a spark. now no spark when we tried to start it. does msd re build these, its brand new like everything else on this boat.

Yes, I think I paid 75. almost 2 yrs ago. I keep a spare now.

...you should have a spare if you're running MSD. (May Soon Die) :drink:

Been there too many times with that junk, not a fan.

They only rebuild the automotive ones, not the marine ones. Due to the fact the marine ones are filled with epoxy.

So are the car ones :drink:

The 6AL "N" and 6an are, but not the 6A or 6AL. The "N" is for nascar guys I think. Talked to MSD last week about this, as one of my marine ones took a crap. Says Im SOL. They will rebuild the 6A or 6AL ones he said. :drink:

"N" series potted with epoxy

i dont know what u guys do, i have never had a problem with my MSD marine box !:party-smiley-004:

School is in session! :drink:

what everybody is telling you is right-on.always carry a spare box and cap/rotor.after 7yr,s w/about 300-400 hrs on it ,i had a failure,box/cap/rotor,i do not know what failed,everything toast,and yea,i had a box[brand new],no cap/rotor.hows that for luck????oh,did i tell you i was 78 miles from home?carry spares,its good stuff,and it works,but chang in china is only going to make it but so good.

make sure you check your coil , cheaper than new box

oops...double post

I know the older stuff was BRUTAL, I had several
MSD7AL2's that would "sit" over the winter and in the Spring suddenly not work? I had good luck with the 7AL3 for the brief time I had it, then switched to a MSD 10 and it worked awesome, but, wasn't all that great on the "street".

I seem to remember years ago being able to wire a "bypass" in my MSD6A so that I could just run without the box if I was ever stuck, cant remember how I wired it, but, could look it up.

I dont know if the new "Digital" stuff is marine certified? But, its probably much more reliable than there old stuff

Just my .02

they must have changed it then,,the 6al on my sub is full of it..i can get the solution that disolves the epoxy, i also may have a place that will fix it..

ART go to the "Testing an MSD" or the - trouble shooting section of the MSD web site, good luck !

If the MSD stuff is so failure prone, then why do people continue to run it?

I have a 6AL part #6420 brand new,never used. You are welcome to try it until you get a marine version.You can pick it up at my shop in Brockton. Jeff 508 400 7413

The one that took a crap on me this summer was a 6M-2 marine box, purchased in 1999. 12-13 years out of it, Im not complaining. I think the main key with these boxes, is mounting them on the transom, or away from the engines, or if you have to mount on the engine, use the rubber feet MSD sells to isolate them from vibrations.

Vibration :eek: what vibration ???:lolhit: been using MSD for years with good luck ,we keep a spare under the seat just incase very cheap insurance :drink:

I've had mine go bad several times. Everytime it would go bad is after the battery had been drained. One time I ran the stereo til the battery was very low. The last time we had a power inverter hooked to a battery to run a lap top which Eddie was using to tune the ECM's. I think one of the things that kills them is Alternators trying to recharge a very discharged battery. They always go out the next time you use them after the incident.

One reason i use the MSD 6T box....it can be fixed. The last one cost 35.00 bucks. Just takes 4 weeks to get back.

No one mentioned the pro comp box. I've had on in my 19' for 4 years now. Not bad for the money.

thanks I got a new one from jim ried right away, thanks though. Artie done for the season well until march, might have to pull the motor to do some work.

Not to sounds like a complete idiot, but why run these boxes, aren't they overkill for most of these engines? I just run the stand alone distributor and cranked out close to 550 horse with it...

My case I always had issues with the Merc chips with the cams i run so I went to a pro comp dist and box. Picked up 200 rpms and made idle perfect. On the race boat I found 2 MSD 6 T boxes on eBay for less then a 100 each. Just cheaper buying the Merc's.
