I mistakenly left the canopy dome light on for a week in my 96 cummins/5 speed with 98,000 miles. As I drove to work each day, I unknowingly was keeping ahead of the discharged batteries, (the tinted canopy windows didn't help the situation. ) That was until I forgot my coffee on the way to work at 0530, stopped at McD's, shut if off at the drive up speaker, and tried to restart it with no luck. I lucked out and managed to push it out of the way. Called my buddy at work and after a jump start, I made it to work, after work a he again stood by to make sure it would fire off, after a couple clicks it did, then when I got home I charged the batteries all night figuring this would solve the problem. The next morning I heard the solenoid click and then it started the next try. When I got to work I searched this site and found that if you don't take care of the solenoid contacts and add a diode, you can have serious problems down the road at around 100k with the 94 to 98 1/2 trucks. I believe it can include(ie, burnt out fuel shutoff solenoid, which costs about $200 to replace, and possibly an engine fire if the starter hangs and can't be shut down) I ordered the parts, rolled the dice, and then drove the truck to work one more time. At 10 pm in the parking lot, it fired off after clicking a couple times and then the high pitched whine of a stuck on starter made me realize that driving it to work one more time was a mistake. I quickly turned the key off, to no avail as the fuel shut off solenoid was being fed from the stuck solenoid contacts. I knew I had to shut it down and quickly. Lucky for me the truck is a 5 speed so I put it into second, held the brake and let out the clutch, it wasn't pretty but it shut it down. I should have left it in the lot and fixed it later, but rolled the dice again and on the second try got it to fire off without the starter staying on. I now have the parts from
http://fostertruck.com/dodge/default.htm but haven't had the time to put them on. The dodge is in the driveway waiting for me. Total cost of parts from foster about $60. Their website states that most starters with the solenoid problem are still in good shape. Sorry for the long post, but hopefully I can save someone from the same situation I faced. Bob
