MSD Digital 7 Ignition Advice.....

[Sparky]

In the past week I have had 3 different isolated incidences of Digital 7 Ignitions experiencing unexplainable problems.

The 3 different Digital 7 Ignitions were exposed to welding on the car with either the Ignition in the car and/or welding on the car while the Ignition was still hooked up.

With the ease of convenience that MSD has built into these Ignitions for removal, I would highly recommend that if you’re going to weld on the car, disconnect and remove the ignition from the car.

I have discussed this before in other post and I can’t stress enough how welding on a car can really mess up electronics.
I don’t think anyone here likes to go out and spend hard earned money on electronics due to neglect while welding on a car.

Don’t gamble on learning about the adverse effects of welding on your car while the electronics were still in the car and installed, at the next race.
Just follow a very simple rule: If you’re going to weld on the car remove the electronics.
That way when you’re done the car it will work as it did prior to welding.

The choice is yours.

Maybe some of the individuals that have been subject to this will speak up and share their experiences.

Great advice.
I too remove mine when doing any welding, always have and always will.

Electricity follows basic laws, with electronics it should not be necessary. But if it gives you comfort, just disconnect the ground wire.

The above mentioned Ignitions were disconnected, including the ground.

The best practice is to just remove the ignition and/or other sensitive electronics while welding.
Why is this even questioned and/or so hard to do? Seems simple enough. :confused:

One of the said ignitions was completely disconnected. It was suspected that the ground clamp on the welder came in contact with the Ignition and caused Ignition failure.

I understand electricity real well and the path electricity travels. But I have seen far too many times that when it comes to sensitive electronics and welders, the electronics end up failing

If there is question on how electricity travels and/or the adverse effects on sensitive electronics while welding. The next time you weld, connect the ground clamp to your tongue and strike an arc......
