Started up the truck this morning and I started smelling burning electrical. I noticed the alternator was making a lot of noise like it was under a huge load but the voltage at the battery was only 12. 4 vdc at best(all accessories off and winch and compressor relays turned off). Then the output dropped off to only battery voltage and the check gauges light came on. I shut down the truck and let it sit for an hour, came back and started up the truck and all is working normally again. The alternator had gotten real hot and I am now concerned with reliability factor. I ran the codes and truck came back with a P1682 (low voltage), P1693 ( companion code) and P500(no input from the speedo). I can understand the first two codes being related but the last one has me confused.

I think I remember somewhere (could not find it in a search) that a problem with the starter could overload the charging system could cuase a similar problem (new aftermarket contacts will fix the problem). My starter did not sould like it was still engaged while the engine was running so I am at a loss to what was causing the power drain.

So any input or suggestions would be great, right now the truck will only be driven very short distances until I can locate the problem.

Also because of the overload, I am considering buying a 205 new amp alternator and needed wiring to replace the OEM alternator. The company is out of Texas and uses a new OEM altenator the is upgraded for 205 amps, has anyone tried using one of thier alternators?.

Sorry for the long post,

If one of the solenoids or the relay for the intake heater sticks it will put a tremendous draw on the system. That happened to me a few days ago, luckily I caught it before any harm was done. Apparently if the alternator can't keep up with the draw it will just shut off, at least that is what mine did. I disconnected the solenoid wires and every thing has worked fine for 3000 miles. Now I'm home and have a brand new set of Stancor solenoids in the garage... ... my next BOMB :D
 
So far there has not been a repeat of the charging failure. There is a new problem with the starter, I turned the key Monday and the starter just clicked a couple of times and then started. I have a new set of contacts/plunger and will install them this weekend. The new alternator is here and that will also install that this weekend. Of course we are going to have temps in the low teens and my truck will not fit into my garage :{ . I am going to check out the heater relays and its circuts. Anyone else have suggestions on how to test out the heater relays?
