TROUBLESHOOTING

Every MSD Ignition undergoes numerous quality control checks including a four hour burn-in test. If 

you experience a problem with your MSD, our research has shown that the majority of problems are 

due to improper installation or poor connections. 

The Troubleshooting section has several checks and tests you can perform to ensure proper installation 

and operation of the MSD. If you have any questions concerning your MSD, call our Customer Support 

Department at (915) 855-7123, 7 - 5 mountain time.
