electrical problems

The wires connecting the EGT probe wire to the little white connector came out and I need to re-attach, re-solder. Does anyone know the correct order of wires - I believe there are 4 and 4 pins. Here is a pic of where the white connector goes (arrow #2), and tonight I will post a pic of the...

While towing my enclosed trailer one night coming home from the dragstrip my trailer brakes pulsated on and off with the turn signal on. Craziest thing having the trailer brakes locking up and releasing in snyc with the blinker. On the way home trying to figure this out in my head I blamed it on...

This past weekend I disconnected both batteries, cleaned the terminals, re-connected everything then started the truck and drove fine. Yesterday I went to start the truck and it turns over but does not start. The WTS light starts flashing the moment it would normally turn off and the wire...

So here's the situation... The truck ('99 3500 4x4 auto 24v) has been sitting unused at my parents house for a about a year now because of a problem my dad found with it where he claimed it would randomly shutoff and he'd have to wait about 30 minutes before he could start and run it again. I...

Three days ago, I went to town (35 mi) with no indication of trouble. When I tried to start the truck later, the batteries were completely dead. I had a truck hooked up for about half an hour before the charge allowed me to start the truck. After starting there was no electrical service...

I noted a "check gauges" warning just as I pulled into my garage and noted low voltage just before I shut off the engine. Next time I went to use the truck, it was stone cold dead. After disconnecting the batteries, I used a continuity tester on the positive battery cable and found it at ground...

I am getting some weird electrical problems with my truck lately. The oddest of the bunch is occasionally I will come back to the truck and the Air conditioning blower is running when I get into the cab. Seems to do this more on really hot days (it was 104 today in San Antonio). No key in...
