Hi There... and I hope someone can help. I have owned a 1991 350SD for many year.. but recently it sat for about 6 weeks unused. As always it started first turn, but as soon as I touched the brake to put it in gear the alarm went off. Took off battery leads to re set computer but as soon as I put them back alarm went off.. door locks shut off alarm but as soon as I touch the brake the alarm sounds.. Any ideas .. Thank you Paul R
