Electrical issues - watch my voltmeter video

[SLCHOE]

What is your amp draw (mV) before and after pulling the RDO AMP fuse?

Those amplifiers do go bad and can cause a draw. I would like to see the data anyway.

And yes, alternators can cause a parasitic drain with the engine off.

Keep in mind that when you are doing amp draw measurements, you need to let the modules in the car go to sleep before you start. Usually on these trucks 5 minutes is plenty.

Also, did not watch your video as it was unavailable.

I checked the draw some time ago and it was substantial w/ that fuse in vis out.

Here is the video:

Bill, Meet @Bigbertha78.

You both have the same issue.

You both need a new alternator.

Thanks a lot, SLCHOE. That has always been in the back of my mind but I think I had it checked once and it was OK. Easy enough to replace so I'm going to do it.

BTW my transmission frequently feels like a slipping clutch - does that mean the torque converter is going out?

Well, where do I go now? :-/ Took it to AutoZone and removed the alternator so they could bench test it. Passed w/ flying colors.

 

[bldn10]

Seduced and abandoned.
Can the alternator be bad and pass the tests?

 

[bldn10]

Still have the problem.
Cameron says my idle is too low but how do you adjust the idle w/ an electronic ignition?

I also have a CEL that comes and goes. Codes are for lean condition. Could it be that when the voltage drops precipitously the fuel pump quits and the resulting mixture triggers the fault code?
