I had a similar episode with my 6AL...........
Unfortunately it was wired HOT all the time when the '88 was built......In a short time it burnt out.......
Called Paul had him come with the trailer and take it to his shop.Jason found the problem immediately.Paul suggested we just send it to MSD to see what might happen.4 days later what arrives........
a brand NEW 6AL for no charge..........
Think they found a problem and shipped a new one anyhow.......
None the less.....I was thrilled and Paul was completely shocked........
