MSD ignition box repair

Here is a shot of my MSD 6A. As You can see the 2 resistors are blown. MSD has refused to fix this even though this box has never been used. (out of warantee) I even offered to pay for the repair but they said they don't do this.

I forgot to take a picture of the whole board but this is at the end where the wires come out.

I can do this kind of soldering but I'm not real sure of the value of the resistors. ie what to ask for when I go to get them. Allied electronics and Radio shack may have them.

Somewhere I saw a post where a guy had done this or a similar repair but I couldn't find it here with search..

what do y'all think??

as best that I can tell those resistors are 19k ohms

and look to be about 1 amp units.

I would go for it, what can it hurt?

You had best look at their website - they, according to the site most certainly will do out of warranty repairs. They also have an on-line RMA section - but it isn't free for those repairs. I wouldn't try a fix - something caused those resistors to blow. From their site:

"Service

In case of malfunction, your MSD component will be repaired free of charges according to the terms of the warranty. When returning MSD components for warranty service, Proof of Purchase must be supplied for warranty verification. After the warranty period has expired, repair service is charged based on a minimum and maximum charge rate. (Contact Customer Service for current rate)"

Another repair service - Tech West: http://www.techwestracing.com/

I sent this unit in for warantee as it had never been used. They replied that it could not be repaired. I even offered to pay for the repairs...not knowing at the time what was wrong. They said that the board was toast. I see nothing wrong what so ever with the board except these 2 resistors.

This unit was installed exactly per their instructions. I even called with a question about the magnetic pickup distributor. An MSD unit.

I've done electronics repairs for years. I personally think I would be hard pressed to repair that board. I would just get another box, but BEFORE hooking it up, correct any wiring errors you might have.

My .02, even for myself I would just get another box. I really hate walking.

I agree, the board is burnt and you dont know what other components are blown. Resistors dont fail on their own. Something else is shorted. Once a board burns it is going to be problems, they really cant be fixed for reliable usage.

I agree on the Mallory & Crane boxes, top notch. MSD=Must Service Defective. MSD=May Shut Down I've had nothing but bad luck with, after the 3rd MSD box I gave up. 6yr old Mallory box still going strong. 8yr old Holley Strip Annihlator no problems.

This raises the question - will either the Mallory (Mr Gasket!!) or Crane boxes work with my MSD 8479 Pro Billet small diameter distributor?

Any experience?

After being inside of the dist. to change springs, there really doesn't seem to be much more of an electronic pickup then a standard Ford, and with the major difference being a GM appearing top mounted advance plate.
