No Start, Electrical help needed

The truck sat for a long time. 4 months or so, only being started once every couple of weeks.

During that time, I recently added headlights, and bumper mounted 'fog' lights.

When I went to start it, it was completely dead. Added two new batteries. Started right up. Voltmeter gauge reads 0, check gauges light is on.

Sat for a few days. Went to start it again. Not completely dead, lights would turn on, and it would turn over, but not start. Put a jump pack on it, and it started right up. Voltmeter gauge still reads 0, and check gauges light is on.

Let it sit overnight and it is back to not starting. Will start to turn over, then just start clicking.

I think it is an alternator problem, but also maybe a slow drain somewhere.

My gameplan is to jump it to get it started. Take it up to Autozone to have the electrical system load tested, and see if it is the alternator. How should I go about seeing if it has a slow drain somewhere?

What do ya'll think? If it is the alternator, what should I replace it with? I'm ok with spending the money to get the best. Thanks for the help!

You can disconnect the positive battery cable from both batteries, hook a test light between the cable and battery post, if the light gets lit you have a draw. Leave the light in place, pull fuses until the light goes out, this will tell you which circuit is creating the draw.

Yeah sounds like one of the new accessories you added is the culprit. If those were set up with inline fuses or plugs then Id start by taking those offline and see if that helps.

Could just be a coincidence too... your batteries could have just rundown too low for too long and theyre dead.

Check for any ECM codes and/or EMIC(cluster) codes ?? will hopefully give clue to issue.
Should verify with real multimeter, 12.6 volts both batteries fully charged with truck off, seen new batteries have issues, Check good wires including grounds to batteries, generator and PDC (Fusebox), voltage drop test easiest, most accurate,should be same as B+ of batteries.
Then check both batteries with truck, running should be 14-15 volts from generator.
DC power alternators IMO way better then OEM.

So...the crossover cable that connects the two batteries was disconnected. I connected it, and no more issue, but the voltmeter gauge is still not working. Is that something that needs to be reset or possibly a fuse?
