I have a '99 Dodge Ram 1500. I drove to my brothers house the other day and my truck ran awesome. (After changing the drive belt.) I tried to leave today, and the truck would not start at all. Not even a click. I had NO electricity. The interior lights would not turn on, no clock. I went to the battery and tried to mess with the cables, checked fuses, and tried to jump start it. Nothing simple worked. Where do I go from here?

Fetch a test light or inexpensive digital voltmeter and start at the battery. Measure the voltage between the two posts. A fully charged battery will read very near 12.6 volts. Move one probe at a time to the cable clamp then to the end of each cable. In particular, move the probe from the negative battery post to the other end of the small black wire where it bolts to the body. It might be helpful to have the light switch turned on because a voltmeter by itself may not draw enough current to make the bad connection show up. You're looking for the place where you no longer have 12 volts or the test light doesn't light. That's the point of the bad connection.

That sounds like a very good idea. But, since my truck is at my brothers house (an hour away) I would like to go with a couple ideas. If everything checks out fine, where should I go from there?

That's all there is on the negative side. Do the same for the positive cable. I seem to recall there will be one smaller red wire that goes to the under-hood fuse box and is bolted on there. The nut should be visible when the cover is popped off. Check that nut to be sure it's tight.

Use the test light or voltmeter to check for voltage on the fuses under the hood. At least some of them will normally have voltage with the ignition switch off. I'll dig up the correct service manual. If you tell me which fuses have voltage and which ones don't, I can figure out the next place to look. If you don't have computer access there, I'll give you my phone number but you'll have to tell me when to expect a call since I'm working outside a lot. You can call up to 1:00 or 2:00 a.M.
