Help please. the 6012 box only lasts from 4 months to 10 days in my car. Has any one had this problem? car runs great and starts great until the box poops to bed. MSD says they have no problems with them.

The 6012 box and ls3 motor is in my 1950 chevy and has been modified some (cam and pistons) the car runs 6.90 in the 1/8th mi and drives very good on the street.

Surely it couldn't be too hard to take these things to an electronics technician to fix them, and upgrade whatever is proving unreliable within the units?

either a power surge, too high a voltage, arcing, or bad grounding is all that comes to mind to cause electrical issues.

What have you checked so far ?

Do you have it mounted in the engine compartment? If you do. Get it out of there. Put it inside away from the heat. It could be getting too hot. Haven't really heard of anyone having problems with the 6012. Unless it was self inflicted. Especially 3 in a row. Make sure your grounds are right. Make sure your power wire is not going into the wiring harness. Dedicated ground and power. Put star washers under all grounds to make sure the are biting in good. A bad chassis ground or bad ground going to the block can cause a back feed through the box. Which will eventually burn it up. Best of luck to you.

I had the same problem with 6aL msd boxes . Its not the 6012 but I do have the 6010 and never had a problem .Mine is in the engine compartment . The fix for my problem was I added grounds to everything . Core support to frame , frame to engine , frame to body , body to engine , battery to frame and then some . Never had a problem again . Must be if you dont have good grounds to everything the system is searching for one and most likley its going thru the 6012 . Being you have had a few boxes burn up my money would be on this being the problem .

The advise above is what input in the FAQ section. I'm at zero 6010/6012 failures personally and I have used a ton of them.

As for being able to fix the MSD 6010 or 6012, not possible. They build them, put all the wiring and electronics in the box and seal it with some crap that is not coming out or off of the components.

Well over the past 10 months and 3 boxes they keep telling me it is a ground problem, The battery ground is hooked to a 3/8 stud welded to the roll cage in the trunk area, I have a cable from cage to the motor and one to the body also the body is mounted solid no rubber . the ground from the 6012 is on a stud welded to the roll bar. the odd thing is that I take it to the track 2 or 3 times and make 4 or 5 passes with no problems. the car runs 6.90s 1/8th mi every time the box goes bad the car has been in the drive way.
just had the alternator checked today and it is just fine . MSD. says any thing under 18 volts.

ZONES89RS, That's true there not repairable. they tell me the third new box is on the way to me.

Run a ground for the box straight to the battery. And ground from the batter to the rolls cage and a ground from the battery to the engine.

streetrod56

ZONES89RS , I have all that and the box is inside the car under the dash, so very dry.

What size/volt battery are you using . Asking due to the 18 volt comment? I would toggle the box to the battery and ground it there also. Follow MSD's recommended grounding procedure.

you said every time it dies its been sitting, do you put a charger on the car when its been sitting?

yup, they're dipped in an epoxy, so no getting into them to repair. the fact that MSD continues to say they have no problems with these boxes (6012 AND 6010) is baffling, and quite frankly, maddening! the box is flat out the most unreliable component on my car. I'm on box number 4 myself.

I'm starting to think that there must be good and bad batches of these boxes. I've had a 6010 in my car for almost 3 years, not one problem. But I do know of others that have had bad experiences with them.

IF my box takes a dump...I'm looking at a Daytona Sensor box and an adapter (I hate wiring)

i'm looking heavily towards a Holley HP and keeping the carb.

streetrod56

Had my car to the 1/8 mi strip tonight and car ran very good. won a race with a friend for $20. made 4 motor passes and tried to shoot 150 hp nos at it but the car never mover, blew the tires off.
so now I guess I just wait until it goes bad again.

I've been on the same 6010 box since 2007.

Your ground for the box should not be hooked to the cage. Proper grounding is to run a dedicated ground straight from the battery to one of the heads. Not the block. At that point is where the box is supposed to be grounded. Then run another ground from that point to the other head. Everything else is to be hooked to the cage or chassis so nothing can back feed through the box. Leave the ground you have going from the block to the cage also. And make sure the power is cut to the box when it is sitting.
